belt lower anchor, front passenger's seat belt outer lap tensioners in the front passenger's seat belt lower anchor, side
curtain airbags in the sides of the roof, and side airbags in the front seat-backs. Information necessary to safely service
the SRS is included in this Service Manual. Items marked w i t h an asterisk ( * ) on the contents page include or are
located near SRS components. Servicing, disassembling, or replacing these items require special precautions and
tools, and should be done only by an authorized Honda dealer.
• To avoid rendering the SRS inoperative, which could lead to personal injury or death in the event of a severe frontal
or side collision, all SRS service w o r k must be performed by an authorized Honda dealer.
• Improper service procedures, including incorrect removal and installation of the SRS, could lead to personal injury
caused by unintentional deployment of the airbags and/or side airbags.
• Do not b u m p or impact the SRS unit, front impact sensors, or side impact sensors w h e n the ignition switch is ON (II),
or for at least 3 minutes after the ignition switch is turned OFF; otherwise, the system may fail in a collision, or the

Lift and Support Points
NOTE: If you are going to remove heavy components
such as the suspension or the fuel tank f r o m the rear of
the vehicle, first support the front of the vehicle w i t h tall
safety stands. W h e n substantial weight is removed
f r o m the rear of the vehicle, the center of gravity can
change causing the vehicle to tip forward on the hoist.
Frame Hoist
Floor Jack
1. When lifting the front of the vehicle, set the parking
brake. W h e n lifting the rear of the vehicle, put the
shift lever in reverse for manual transmission, or in
the P position for automatic transmission.
2. Block the wheels that are not being lifted.
1. Position the hoist lift blocks (A) under the vehicle's'
front support points (B) and rear support points (C).
3. Position the floor jack under the front jacking
bracket (A) or the rear jacking bracket (B). Center
the jacking bracket in the jack lift platform (C), and
jack up the vehicle high enough to fit the safety
stands under it.

2. Raise the hoist a f e w inches, and rock the vehicle
gently to be sure it is f i r m l y supported.
3. Raise the hoist to its full height, and inspect the lift
points for solid contact w i t h the lift blocks.
Safety Stands

4. Position the safety stands under the support points,
and adjust t h e m so the vehicle is level.
5. Lower the vehicle onto the stands.
To support the vehicle on safety stands, use the same
support points (B and C) as for a frame hoist. Always
use safety stands w h e n working on or under any
vehicle that is supported only by a jack.

General Information
Towing
If the vehicle needs t o be t o w e d , call a professional
t o w i n g service. Never t o w the vehicle behind another
vehicle w i t h a rope or chain. It is very dangerous.
Emergency Towing
There are three popular methods of t o w i n g a vehicle.
Flat-bed Equipment — The operator loads the vehicle
on the back of a truck. This is the best way of
transporting the vehicle.
To accommodate flat-bed equipment, the vehicle is
equipped w i t h a front t o w i n g hook (A), front tie d o w n
hook slots (B), rear t o w i n g hook (C), and rear tie d o w n
hook slots (D).
The t o w i n g hook can be used w i t h a winch to pull the
vehicle onto the truck, and the tie d o w n hook slots can
be used to secure the vehicle to the truck.

Front Towing Hook Installation
1. Remove the cover (A) f r o m the front bumper.
Wheel Lift Equipment — The t o w truck uses t w o
pivoting arms that go under the tires (front or rear) and
lift t h e m off the ground. The other t w o wheels remain
on the ground. This is an acceptable w a y of towing the
vehicle.
Sling-type Equipment — The t o w truck uses metal
cables w i t h hooks on the ends. These hooks go around
parts of the frame or suspension and the cables lift that
end of the vehicle off the ground. The vehicle's
suspension and body can be seriously damaged if this
method of t o w i n g is attempted.
If the vehicle cannot be transported by a flat-bed, it
should be t o w e d w i t h the front wheels off the ground. If
the vehicle is damaged, the vehicle must be t o w e d w i t h
the front wheels on the ground.
2. Remove the t o w i n g hook (B) f r o m the tool kit.
3. Screw the t o w i n g hook into the bolt hole (C) in the
bumper and tighten it securely by hand.
Manual Transmission
• Release the parking brake.
• Shift the transmission to neutral.
• Leave the ignition switch in the ACCESORY (I)
position so the steering wheel does not lock.
Automatic Transmission
• Release the parking brake.
° Start the engine.
• Shift to the D position, then to the N position.
• Turn off the engine.
• Leave the ignition switch in the ACCESORY (I)
position so the steering wheel does not lock.
It is best to t o w the vehicle no farther than 50 miles
(80 km), and keep the speed below 35 mph (55 km/h).
NOTlCEl
• Improper t o w i n g preparation will damage the
transmission. Follow the above procedure exactly. If
you cannot shift the transmission or start the engine
(automatic transmission), the vehicle must be
transported on a flat-bed.
• Trying to lift or t o w the vehicle by the bumpers will
cause serious damage. The bumpers are not
designed to support the vehicle's w e i g h t
General Information
Parts Marking
To deter vehicle theft, certain major components are marked w i t h the vehicle identification number (VIN). Original
parts have self-adhesive labels. Replacement body parts have generic self-adhesive labels. These labels should not be
removed. The original engine or transmission VIN plates are not transferable to the replacement engine or
transmission.
NOTE: Be careful not to damage the parts marking labels during body repair. Mask the labels before repairing the part.

Resetting the Maintenance Information
Display
NOTE;
• The vehicle must be stopped to reset
• If the required service is performed and the display is
not reset, or if the display is reset w i t h o u t performing
the service, the system will not show the proper
maintenance t i m i n g . This can lead to serious
mechanical problems because there will be no record
of w h e n maintenance is needed.
• The engine oil life and the maintenance items may be
reset independently only w i t h the HDS.
1. Turn the ignition switch ON (II).
2. If oil life is more than 15 %, press the Select/Reset
Knob repeatedly until the engine oil life is
displayed.
3. Press the Select/Reset- Knob for about 10 seconds.
The engine oil life and the maintenance item
code(s) will blink.
NOTE: If you are resetting the display w h e n the oil
life is more than 15 %, make sure the maintenance
items requiring service have been performed
before resetting this display.
4. Press the Select/Reset Knob for another 5 seconds.
The maintenance item code(s) will disappear, and
the engine oil life will reset to " 1 0 0 . "

Spark Plug Inspection.
1. Inspect the electrodes and the ceramic insulator.
• Burned or w o r n electrodes may be caused by:
- Advanced ignition t i m i n g
- Loose spark plug
- Plug heat range too hot
- Insufficient cooling
• Fouled plugs may be caused by:
- Retarded ignition t i m i n g
- Oil in combustion chamber
- Incorrect spark plug gap
- Plug heat range too cold
- Excessive idling/low speed running
- Clogged air cleaner element
- Deteriorated ignition coils
Replace the plug at the specified interval, if the
center electrode is rounded (A), or if the spark plug
gap is out of specification. Use only the listed spark
plugs.
NOTE: Do not adjust the gap (B) of iridium tip plugs.

Engine Compression Inspection
NOTE: After this Inspection, you must reset the engine
control module (ECM)/ powertrain control module
(PCM), otherwise the ECM/PCM will continue to stop
the injectors f r o m functioning. Select ECM/PCM reset
using the Honda Diagnostic System (HDS) (see page
11-4).
1. W a r m up the engine to normal operating
temperature (cooling fan comes on).
10. Open the throttle fully, then crank the engine w i t h
the starter motor and measure the compression.
Compression Pressure:
Above 980 kPa (10.0 kgf/cm ,142 psi)-250 rpm
2
11, Measure the compression on the remaining
cylinders.
Maximum variation:
Within 200 kPa (2.0 kgf/cm ,28 psi)
2
2. Turn the ignition switch OFF.
3. Connect the HDS to the data link connector (DLC)
(see step 2 on page 11-3).
12, If the compression is not w i t h i n specifications,
check the following items, then remeasure the
compression.
4. Turn the ignition switch ON (II).
5. Make sure the HDS communicates w i t h the vehicle
and the ECM/PCM. If it doesn't, troubleshoot the
DLC circuit (see page 11-174).
6. Select PGM-FI, INSPECTION, then ALL INJECTORS
OFF function on the HDS.
7. Remove the four ignition coils (see page 4-21).
8. Remove the four spark plugs.
9. Attach the compression gauge to the spark plug
hole.
NOTE: Use a compression gauge of which
connecting length (between the edge and the
flange) is less than 23 m m (0.9 in.).

same procedure can be done using the special tool
and a conventional hammer.
5. Working f r o m the camshaft side, use the driver and
an air hammer to drive the guide about 2 m m
(0.1 in.) towards the combustion chamber. This will
knock off some of the carbon and make removal
easier. Hold the air h a m m e r directly in line w i t h the
valve guide to prevent damaging the driver.

Cylinder Bore Honing
Only a scored or scratched cylinder bore must be honed.
1. Measure the cylinder bores (see page 7-16).
If the engine block is to be reused, hone the
cylinders and remeasure the bores.
2. Hone the cylinder bores w i t h honing oil and a fine
(400 grit) stone in a 60 degree cross-hatch pattern
(A). Use only a rigid hone w i t h 400 grit or finer
stone such as Sunnen, A m m c o , or equivalent. Do
not use stones that are w o r n or broken.
3. When honing is complete, thoroughly clean the
engine block of all metal particles. Wash the
cylinder bores w i t h hot soapy water, then dry and
oil t h e m immediately to prevent rusting. Never use
solvent, it will only redistribute the grit on the
cylinder walls.
4. If scoring or scratches are still present in the
cylinder bores after honing to the service limit,
rebore the engine block. Some light vertical scoring
and scratching is acceptable If it is not deep enough
to catch your fingernail and does not run the full
length of the bore.

malfunction indicator lamp (MIL) on the dash does not
come on, check for poor connections or loose pins at all
connectors related to the circuit that you are
troubleshooting. If the MIL was on but then w e n t out,
the original problem may have been intermittent.
2. If the MIL stays on, connect the HDS to the data link
connector (DLC) (A) located under the driver's side
of the dashboard.
Opens and Shorts
" O p e n " and " s h o r t " are c o m m o n electrical terms. An
open is a break in a wire or at a connection. A short is
an accidental connection of a wire to ground or to
another wire. In simple electronics, this usually means
something w o n ' t work at all. With complex electronics
(such as ECMs or PCMs) this can sometimes mean
something works, but not the w a y it's supposed to.
How to Use the HDS (Honda Diagnostic
System)
If the MIL (malfunction indicator lamp) has come on, do
this:
3. Turn the ignition switch ON (II).
4. Check the diagnostic trouble code (DTC) and note it.
Also check the freeze data and/or on-board
snapshot data, and download any data found. Then
refer to the indicated DTCs troubleshooting, and
begin the appropriate troubleshooting procedure.
1. Start the engine, and check the MIL (A).
NOTE; If the ignition switch is turned ON (II), and
the engine is not started, the MIL stays on for
15—20 seconds (see page 11-53).
NOTE:
• Freeze data indicates the engine conditions w h e n
the first malfunction, misfire, or fuel t r i m
malfunction was detected.
• The HDS can read the DTC, freeze data, on-board
snapshot, current data, and other engine control
module (ECM) or powertrain control module
(PCM) data.
• For specific operations, refer to the user's
manual that came w i t h the HDS.
5. If no DTCs are f o u n d , go to MIL troubleshooting
(see page 11-173).
If the MIL did not stay on
If the MIL did not stay on but there is a driveability
problem, do the s y m p t o m troubleshooting.
If you can't duplicate the DTC
Some of the troubleshooting requires you to reset the
ECM/PCM and try to duplicate the DTC. If the problem is
intermittent and y o u can't duplicate the code, do not
continue through the procedure. To do so will only
result in confusion and possibly, a needlessly replaced
ECM/PCM.

HDS Clear Command
The ECM/PCM stores various specific data to correct the
system even if there is no electrical power such as
when the battery negative terminal or No. 14 IGP (15 A)
fuse are disconnected. Stored data based on failed
parts should be cleared by using the "CLEAR
C O M M A N D " of the HDS, if parts are replaced.
The HDS has three kinds of clear commands to meet
this purpose. They are DTC clear, ECM/PCM reset, and
CKP pattern clear. DTC clear c o m m a n d erases all stored
DTC codes, freeze data, on-board snapshot, and
readiness codes. This must be done w i t h the HDS after
reproducing the DTC during troubleshooting.
The ECM/PCM reset c o m m a n d erases all stored DTC
codes, freeze data, on-board snapshot, readiness codes,
and all specific data to correct the system except CKP
pattern. If the CKP pattern data in the ECM/PCM was
cleared, you must do the CKP pattern learn procedure.
The CKP pattern clear c o m m a n d erases only CKP
pattern data. This c o m m a n d is for repair of a misfire or
the CKP sensor.
ECM/PCM Reset
1. Reset the ECM/PCM with the HDS while the engine
is stopped.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON (II), and wait for
30 seconds.
4. Turn the ignition switch OFF, and disconnect the
HDS f r o m the DLC.
5. Do the ECM/PCM idle learn procedure (see page
11-268).
Crank (CKPJ Pattern Clear/Crank (CKP)
Pattern Learn
Clear/Learn Procedure (with the HDS)
1. Connect the HDS to the data link connector (DLC)
(A) located under the driver's side of the dashboard.
Scan Tool Clear Command
If you are using a generic scan tool to clear c o m m a n d s ,
be aware that there is only one setting for clearing the
ECM/PCM, and it clears all commands at the same t i m e
(CKP pattern learn, idle learn, readiness codes, freeze
data, on-board snapshot, and DTCs). After you clear all
commands, you then need to do these procedures, in
this order: ECM/PCM idle learn procedure (see page
11-268); CKP pattern learn procedure;
Test-drive to set readiness codes to complete (see page
11-53).
DTC Clear
1. Clear the DTC w i t h the HDS while the engine is
stopped.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON (II), and wait for
30 seconds.
4. Turn the ignition switch OFF, and disconnect the
HDS f r o m the DLC.

2. Turn the ignition switch ON (II).
3. Make sure the HDS communicates w i t h the ECM/
PCM. If it doesn't, go to the DLC circuit
troubleshooting (see page 11-174).
4. Select CRANK PATTERN in the ADJUSTMENT
MENU w i t h the HDS.
5. Select CRANK PATTERN LEARNING w i t h the HDS,
and f o l l o w the screen prompts.
Learn Procedure (without the HDS)
1. Start the engine. Hold the engine speed at
3,000 r p m without load (in Park or neutral) until the
radiator fan comes on.
2. Test-drive the vehicle on a level road: Decelerate
(with the throttle fully closed) f r o m an engine speed
of 2,500 rpm d o w n to 1,000 rpm w i t h the A/T in
2 position, or MfT in 1st gear.
3. Repeat step 2 several times.
4. Turn the ignition switch OFF.
5. Turn the ignition switch ON (II), and wait for
30 seconds. The CKP pattern learn procedure is
complete.
How to End a Troubleshooting Session
(required after any troubleshooting)
1. Reset the ECM/PCM w i t h the HDS.
2. Do the ECM/PCM idle learn procedure (see page
11-268).
3. Turn the ignition switch OFF.
4. Disconnect the HDS f r o m the DLC.
NOTE: The ECM/PCM is part of the immobilizer
system. If y o u replace the ECM/PCM, it will have a
different immobilizer code. In order for the engine
to start, y o u must rewrite the immobilizer code w i t h
the HDS.

ECM/PCM Updating and Substitution for
Testing
1. Turn the ignition switch ON (II), but do not start the
engine.
Special Tools Required
• Honda diagnostic system (HDS) TDSGDS2200 *
• Honda interface module (HIM) EQS05A35570 *
°HDS pocket tester TDSS3557011401
• Available through the Honda Tool and Equipment
Program
2. Connect the HDS to the data link connector (DLC)
(A) located under the driver's side of the dashboard.
Use this procedure w h e n y o u have to substitute a
known-good ECM/PCM or update the ECM/PCM in a
troubleshooting procedure.
Updating the ECM/PCM
NOTE:
• Make sure the HDS/HIM has the latest software
version.
• Before you update the ECM/PCM, make sure the
battery in the vehicle is fully changed.
• Never turn the ignition switch OFF during the update.
If there is a problem w i t h the update, leave the
ignition switch ON.
• To prevent ECM/PCM damage, do not operate
anything electrical (headlights, audio system, brakes,
A/C, power w i n d o w s , door locks, etc.) during the
update.
• To ensure the latest program is installed, do an ECM/
PCM update whenever the ECM/PCM is substituted or
replaced.
• You cannot update an ECM/PCM with a program it
already has. It will only accept a new program.
• If y o u need to diagnose the Honda interface module
(HIM) because the HIM's red ( # 3 ) lamp came on or
was flashed during the update, leave the ignition
switch in the ON (II) position w h e n you disconnect the
HIM f r o m the data link connector (DLC). This will
prevent ECM/PCM damage.
3. Make sure the HDS communicates w i t h the ECM/
PCM. If it doesn't, go to the DLC circuit
troubleshooting (see page 11-174). If you are
returning f r o m the DLC circuit troubleshooting, skip
steps 4 and 5, then clean the throttle body after
updating the ECM/PCM (see page 11-306).
4. Select the INSPECTION MENU w i t h the HDS.
5. Select the ETCS TEST, then select the TP POSITION
CHECK, and f o l l o w the screen prompts w i t h the

7. If the software in the ECM/PCM is the latest
disconnect the HDS/HIM f r o m the DLC, and go back
to the procedure that you were doing. If the
software in the ECM/PCM is not the latest, f o l l o w
the instructions on the screen. If prompted to
choose the PGM-FI system or the A/T system, make
sure you update both.
NOTE: If the ECM/PCM update system requires y o u
to cool the ECM/PCM, f o l l o w the screen prompts. If
you run into a problem (programming takes over
15 minutes, status bar goes over 100 %, D4 or
immobilizer indicator flashes, HDS tablet freezes,
etc.) during the update procedure, f o l l o w these
steps to minimize the chance of damaging the
ECM/PCM:
• Leave the ignition switch in the " O N (II)" position.
• Connect a jumper battery (do not connect a
battery charger).
• Shut d o w n the HDS.
• Disconnect the HDS f r o m the HDS.

Fuel and Emissions Systems
S f s t e m Description
Electronic Control S f stem
The fuel and emission control systems are managed by the engine control module (ECM) on vehicles w i t h manual
transmissions or the powertrain control module (PCM) on vehicles w i t h automatic transmissions.
Self-diagnosis
The ECM/PCM detects a failure of a signal f r o m a sensor or f r o m another control unit and stores a Temporary DTC or a
DTC in erasable m e m o r y (RAM). Depending on the failure, a DTC is stored in either the first or the second drive cycle.
W h e n a DTC is stored, the ECM/PCM turns on the malfunction indicator lamp (MIL) by supplying ground to the MIL
circuit
• One Drive Cycle Detection Method
W h e n an abnormality occurs in the signal f r o m a sensor or f r o m another control unit, the ECM/PCM stores a DTC for
the failure in the RAM and turns on the MIL immediately.
- T w o Drive Cycle Detection Method
W h e n an abnormality occurs in the signal f r o m a sensor or f r o m another control unit in the first drive cycle, the
ECM/PCM stores a Temporary DTC for the failure in RAM. The MIL does not come on at this time. If the failure
continues in the second drive cycle, the ECM/PCM stores a DTC in erasable-memory and turns on the MIL.
Fail-safe Function
W h e n an abnormality occurs in the signal f r o m a sensor or f r o m another control unit, the ECM/PCM ignores that signal
and substitutes a pre-programmed value for them that allows the engine to continue running. This causes a DTC to be
stored and the MIL to come on.
MIL Bulb Check and Readiness Code Condition
W h e n the ignition switch is turned ON (II), the ECM/PCM supplies ground to the MIL circuit for about 15 to 20 seconds
to check the bulb condition. If any readiness codes are not set to complete, the MIL flashes five times. If all readiness
codes are set to complete, the MIL goes off.
Self Shut Down (SSD) Mode
After the ignition switch is turned OFF, the ECM/PCM stays on (up to 25 minutes). If the ECM/PCM connector is
disconnected during this t i m e , the ECM/PCM may be damaged. To cancel this mode, disconnect the negative cable
f r o m the battery or j u m p the SCS line w i t h the HDS after the ignition switch is turned OFF.

Fuel and Emissions Systems
S y s t e m Description (cont'd)
PGM-FI System
The programmed fuel injection (PGM-FI) system is a
sequential multiport fuel injection system.
Crankshaft Position (CKP) Sensor
The CKP sensor detects crankshaft speed and is used by
the ECM/PCM to determine ignition t i m i n g and t i m i n g
for fuel injection of each cylinder as well as detecting
engine misfire.
Air Conditioning (A/C) Compressor Clutch Relay
When the ECM/PCM receives a demand for cooling
f r o m the A/C system, it delays the compressor f r o m
being energized, and enriches the mixture to assure
smooth transition to the A/C mode.
Air Fuel Ratio (A/F) Sensor
The A/F sensor operates over a w i d e air/fuel range. The
A/F sensor is installed upstream of the TWC, and sends
signals to the ECM/PCM which varies the duration of
fuel injection accordingly.

Ignition Timing Control
The ECM/PCM contains the m e m o r y for basic ignition
t i m i n g at various engine speeds and manifold absolute
pressures. It also adjusts the t i m i n g according to engine
coolant temperature and intake air temperature.
Injector Timing and Duration
The ECM/PCM contains the m e m o r y for basic discharge
duration at various engine speeds and manifold
pressures. The basic discharge duration, after being
read out f r o m the m e m o r y , is further modified by
signals sent f r o m various sensors to obtain the final
discharge duration.
By monitoring long term fuel t r i m , the ECM/PCM
detects long term malfunctions in the fuel system and
sets a diagnostic trouble code (DTC).
Intake Air Temperature flAT) Sensor
The IAT sensor is a temperature dependent resistor
(thermistor). The resistance of the thermistor decreases
as the intake air temperature increases.
TERMINAL
Knock Sensor
The knock control system adjusts the ignition t i m i n g to
minimize knock.
Malfunction Indicator Lamp (MIL) Indication (In relation
to Readiness Codes)
The vehicle has certain "readiness c o d e s " that are part
of the on-board diagnostics for the emissions systems.
If the vehicle's battery has been disconnected or gone
dead, if the DTCs have been cleared, or if the ECM/PCM
has been reset, these codes are reset. In some states,
part of the emissions testing is to make sure these
codes are set to complete. If all of them are not set to
complete, the vehicle may fail the test, or the test
cannot be finished.
To check if the readiness codes are set to complete,
turn the ignition switch ON (II), but do not start the
engine. The MIL will come on for 15—20 seconds. If it
then goes off, the readiness codes are complete. If it
flashes five times, one or more readiness codes are not
complete. To set each code, drive the vehicle or run the
engine as described in the procedures (see page 11-53).
Manifold Absolute Pressure (MAP) Sensor
The MAP sensor converts manifold absolute pressure
into electrical signals to the ECM/PCM.

Secondary Heated Oxygen Sensor (Secondary H02S)
The secondary H02S detects the oxygen content in the
exhaust gas downstream of the three w a y catalytic
converter ( T W O , and sends signals to the ECM/PCM
which varies the duration of fuel injection accordingly.
To stabilize its output, the sensor has an internal heater.
The ECM/PCM compares the H02S output w i t h the A/F
sensor output to determine catalyst efficiency. The
secondary H02S is located on the TWC.

Electronic Throttle Control System
The throttle is electronically controlled by the electronic
throttle control system. Refer to the system diagram to
see a functional layout of the system.
Idle control: When the engine is idling, the ECM/PCM
controls the throttle actuator to maintain the proper idle
speed according to engine loads.
Acceleration control: When the accelerator pedal is
pressed, the ECM/PCM opens the throttle valve
depending on the accelerator pedal position (APP)
sensor signal.
Cruise control: The ECM/PCM controls the throttle
actuator to maintain set speed w h e n the cruise control
is operating. The throttle actuator takes the place of the
cruise control actuator.

Vehicle Speed Sensor (VSS) (M/T)
The VSS is driven by the differential. It generates a
pulsed signal f r o m an input of 5 volts. The number of
pulses per minute increases/decreases w i t h the speed
of the vehicle.
11-34
Accelerator Pedal Position (APP) Sensor
As the accelerator pedal position changes, the sensor
varies the signal voltage to the ECM/PCM.
Throttle Body
The throttle body is a single-barrel side draft type. The
lower portion of the throttle valve is heated by engine
coolant f r o m the cylinder head to prevent icing of the
throttle plate.
idle Control System
W h e n the engine is cold, the A/C compressor is on, the
transmission is in gear, the brake pedal is pressed, the
power steering load is high, or the alternator is
charging, the ECM/PCM signals or communicates w i t h
the throttle actuator to maintain the correct idle speed.

Fuel Cutoff Control
During deceleration w i t h the throttle valve closed,
current to the injectors is cut off to improve fuel
economy at engine speeds over 900 rpm (1,050 rpm on
Canada models). Fuel cutoff also occurs w h e n the
engine speed exceeds 6,700 r p m , regardless of the
position of the throttle valve, to protect the engine f r o m
over-revving. W h e n the vehicle is stopped, the ECM/
PCM cuts the fuel at engine speeds over
5,000 rpm (A/T), 6,700 rpm (M/T). The engine speed of
fuel cut is lower on a cold engine.
Fuel Pump Control
W h e n the ignition is turned on, the ECM/PCM grounds
PGM-FI main relay 2 (FUEL PUMP) which feeds current
to the fuel p u m p for 2 seconds to pressurize the fuel
system. With the engine running, the ECM/PCM
grounds PGM-FI main relay 2 (FUEL PUMP) and feeds
current to the fuel p u m p . When the engine is not
running and the ignition is on, the ECM/PCM cuts
ground to PGM-FI main relay 2 (FUEL PUMP) which cuts
current to the fuel p u m p .
PGM-FI Main Relay 1 (Fl MAIN) and 2 (FUEL PUMP)
PGM-FI main relay 1 (Fl MAIN) is energized whenever
the ignition switch is ON (II) to supply battery voltage to
the ECM/PCM, power to the injectors, and power for
PGM-FI main relay 2 (FUEL PUMP). PGM-FI main relay 2
(FUEL PUMP) is energized to supply power to the fuel
p u m p for 2 seconds w h e n the ignition switch is turned
ON (II), and w h e n the engine is cranking or running.

The ECM/PCM detects whether the fuel fill cap is loose
or missing under certain conditions and alerts the
driver by showing the information in the information
display. If the ECM/PCM detects a small v o l u m e leak,
the MIL may come on during the third drive cycle and
store a DTC.
First drive cycle
During the first drive cycle after a cold start, the ECM/
PCM alerts the driver to check the fuel fill cap by
showing a "CHECK FUEL CAP" message in the
information display (A), and it stores Temporary
DTC P0457 "Evaporative Emission (EVAP) System Leak

Procedure
1. Tighten the fuel fill cap until it clicks.
2. Turn the ignition switch OFF.
3. Start the engine, and drive at a steady speed over
28 mph (45 km/h), without moving the accelerator
pedal, for about 1 minute. Do step 2 and 3 several
times.
Second drive cycle
During the second drive cycle after a cold start, if the
fuel fill cap is still loose or missing, the ECM/PCM alerts
the driver to check the fuel fill cap by showing a
"CHECK FUEL CAP" message in the information display
the same as the first drive cycle. Tightening the fuel cap
does not make the message go off immediately.
Third drive cycle
During the third drive cycle after a cold start, if the fuel
fill cap is still loose or missing, the ECM/PCM stores
DTC P0457 "Evaporative Emission (EVAP) System Leak

How to Set Readiness Codes
Malfunction Indicator Lamp {MIL) Indication
(In relation to Readiness Codes)
Catalytic Converter Monitor and Readiness
Code
The vehicle has certain "readiness c o d e s " that are part
of the on-board diagnostics for the emissions systems.
If the vehicle's battery has been disconnected or gone
dead, if the DTCs have been cleared, or if the ECM/PCM
has been reset, these readiness codes are reset to
incomplete. In some states, part of the emissions
testing is to make sure these codes are set to complete.
If all of them are not set to complete, the vehicle may
fail the emission test, or the test cannot be finished.
NOTE:
• Do not turn the ignition switch off during the
procedure.
• All readiness codes are cleared w h e n the battery is
disconnected, if the DTCs have been cleared, or if the
ECM/PCM is reset w i t h the HDS.
• Low ambient temperatures or excessive stop-and-go
traffic may increase the drive t i m e needed to switch
the readiness code f r o m incomplete to complete.
• The readiness code will not switch to complete until
all the enable criteria are met.
If a fault in the secondary H02S system caused the
MIL to come on, the readiness code cannot be set to
complete until you correct the f a u l t
To check if the readiness codes are set to complete,
turn the ignition switch ON (II), but do not start the
engine. The MIL w i l l come on for 15—20 seconds. If it
then goes off, the readiness codes are set to complete.
If it flashes five times, one or more readiness codes are
not set to complete. To set readiness codes f r o m
incomplete to complete, do the procedure for the
appropriate code.
To check the status of a specific DTC system, check the
OBD status in the DTC MENU w i t h the HDS (see page
11-9). This screen displays the code, the current data list
of the enable criteria, and the status of the readiness
testing.
9
Enable Criteria
• ECT at 158 T (70 °C) or more.
• Intake air temperature (IAT) at 20 T ( —7 °C) or more.
Vehicle speed sensor (VSS) above 25 mph (40 km/h).
e
Procedure
1. Connect the HDS to the vehicle's data link
connector (DLC), and bring up the READINESS
CODEs screen for Catalyst in the DTCs MENU.
2. Start the engine.
3. Test-drive the vehicle under stop-and-go conditions
w i t h short periods of steady cruise. After about
5 miles (8 km), the readiness code should switch to
complete.
4. If the readiness code is still not set to complete,
check for a Temporary DTC w i t h the HDS. If there is
no DTC, one or more of the enable criteria were
probably not met; repeat the procedure.

ECM/PCM is reset w i t h the HDS.
Enable Criteria
• Battery voltage is more than 10.5 V.
• Engine at idle.
• ECT sensor 1 and 2 between 176 °F (80 °C) and 212 °F
(100 ^C).
• MAP sensor less than 46.6 kPa (14 in.Hg, 350 m m H g ) .
• Vehicle speed 0 m p h (0 km/h).
• I AT sensor between 32 °F (0 °C) and 212 T (100 <C).
Enable Criteria

Procedure
1. Start the engine.
Procedure
1. Connect the HDS to the DLC.
2. Start the engine.
3. Select EVAP TEST in the INSPECTION MENU w i t h
the HDS, then select the FUNCTION TEST in the
EVAP TEST MENU.
• If the result is normal, readiness is complete.
• If the result is not normal, go to the next step.
4. Check for a Temporary DTC. If there is no DTC, one
or more of the enable criteria were probably not
met; repeat the procedure.
2. Test-drive the vehicle under stop-and-go conditions
w i t h short periods of steady cruise. During the
drive, decelerate (with the throttle fully closed) for
5 seconds. After about 3.5 miles (5.6 km), the
readiness code should switch f r o m incomplete to
complete.
3. Check the readiness codes screen for the AIR FUEL
RATIO (A/F) SENSOR in the DTCs MENU w i t h the
HDS.
• If the screen shows complete, readiness is
complete.
• If the screen shows not complete, go to the next
step.
4. Check for a Temporary DTC. If there is no DTC, the
enable criteria was probably not met. Select the
DATA LIST MENU. Check the ECT in the ALL DATA
LIST w i t h the HDS. If the ECT is less than 140 T
(60 °C), run the engine until it is more than 140 °F
(60 °C), then repeat the procedure.

Procedure
Misfire Monitor and Readiness Code
• This readiness code is always set to available
because misfiring is continuously monitored.
• Monitoring pauses, and the misfire counter resets, if
the vehicle is driven over a rough road.
• Monitoring also pauses, and the misfire counter
holds at its current value, if the throttle position
changes more than a predetermined value, or if
driving conditions fall outside the range of any
related enable criteria.
Fuel S f stem Monitor and Readiness Code
• This readiness code is always set to available
because the fuel system is continuously monitored
during closed loop operation.
• Monitoring pauses w h e n the catalytic converter,
EVAP control system, and A/F sensor monitors are
active.
• Monitoring also pauses when any related enable
criteria are not being met. Monitoring resumes w h e n
the enable criteria is again being m e t
ECT at 176 T (80 °C) or more.

100 km/h) or above for more than 10 seconds.
4. With the A/T in D position or M/T in 4th gear,
decelerate f r o m 62 m p h (100 km/h) or above by
completely releasing the throttle for at least
5 seconds. If the engine is stopped during this
procedure, go to step 3 and do the procedure again.
5. Check the OBD status screen for DTC P0401 in the
DTCs MENU with the HDS.
• If it is passed, readiness is complete.
• If it is not passed, go to step 3 and retest.

Canada models:
M/T
8 5 0 ± 5 0 rpm
8 5 0 ± 5 0 rpm (in Park or neutral)
A/T
7. Let the engine idle for 1 minute with high electric
load (A/C switch o n , temperature set to max cool,
blower fan on High, and headlights on high beam),
Idle speed should be:
M/T
8 5 0 ± 5 0 rpm
8 5 0 ± 5 0 rpm (in Park or neutral)
A/T
NOTE: If the idle speed is not w i t h i n specification,
do the ECM/PCM idle learn procedure (see page

E C I V S / P C M Idle Learn Procedure
The Idle learn procedure must be done so the ECM/PCM
can learn the engine idle characteristics.
Do the idle learn procedure whenever you do any of
these actions:
•
•
•
•
Replace ECM/PCM.
Reset ECM/PCM.
Update ECM/PCM.
Replace or clean the throttle body.
NOTE: Erasing DTCs w i t h the HDS does not require you
to do the idle learn procedure.
Procedure
1. Make sure all electrical items (A/C, audio, lights, etc.)
are off.
2. Reset the ECM/PCM with the HDS.
3. Turn the ignition switch ON (II), and w a i t 2 seconds.
4. Start the engine. Hold the engine speed at
3,000 rpm without load (in Park or neutral) until the
radiator fan comes on, or until the engine coolant
temperature reaches 194 °F (90 °C).
5. Let the engine idle for about 5 minutes w i t h the
throttle fully closed.
NOTE: If the radiator fan comes o n , do not include
its running time in the 5 minutes.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS) (if automatic transmission maintenance is
required)
The Fit SRS includes a driver's airbag in the steering wheel hub, a passenger's airbag in the dashboard above the
glove box, seat belt tensioners in the front seat belt retractors, driver's seat belt outer lap tensioner in the driver's seat
belt lower anchor, front passenger's seat belt outer lap tensioners in the front passenger's seat belt lower anchor, side
curtain airbags in the sides of the roof, and side airbags in the front seat-backs. Information necessary to safely service
the SRS is included in this Service Manual. Items marked w i t h an asterisk ( * ) on the contents page include or are
located near SRS components. Servicing, disassembling, or replacing these items require special precautions and
tools, and should be done only by an authorized Honda dealer.
• To avoid rendering the SRS inoperative, which could lead to personal injury or death in the event of a severe frontal
or side collision, all SRS service work must be performed by an authorized Honda dealer.
• Improper service procedures, including incorrect removal and installation of the SRS, could lead to personal injury
caused by unintentional deployment of the airbags and/or side airbags.
• Do not bump or impact the SRS unit, front impact sensors, or side impact sensors w h e n the ignition switch is ON (II),
or for at least 3 minutes after the ignition switch is turned OFF; otherwise, the system may fail in a collision, or the
airbags may deploy.
• SRS electrical connectors are identified by yellow color coding. Related components are located in the steering
column, front console, dashboard, dashboard lower panel, in the dashboard above the glove box, in the front seats,
in the roof side, and around the floor. Do not use electrical test equipment on these circuits.

H o w to C h e c k f o r DTCs w i t h t h e SCS Mode
(retrieving t h e f l a s h c o d e s )
If the D indicator and the MIL come on at the same time,
or if a driveability problem is suspected, do this;
NOTE; The preferred method Is t o use the HDS to
retrieve the P-code.
1. Connect the HDS to the DLC. (See the HDS user's
manual for specific instructions.)
When the PCM senses an abnormality in the input or
output system, the D indicator (A) in the gauge control
module (B) will usually blink.
2. Turn the ignition switch ON (II), select SCS mode,
then observe the D indicator in the gauge control
module. Codes 1 through 9 are indicated by
individual short blinks. Codes 10 and above are
indicated by a series of long and short blinks. One
long blink equals 10 short blinks. Add the long and
short blinks together to determine the code.
7-position
NOTE; If the HDS does not communicate w i t h the
PCM, troubleshoot the DLC circuit (see page
11-174).

3. Record all fuel and emissions DTCs and A/T DTCs.
When the D indicator has been reported o n , connect the
HDS to the DLC (A) (located behind the driver's
dashboard lower cover). Turn the ignition switch ON (II),
select SCS mode, then the D indicator will indicate flash
the DTC.
4. If there is a fuel and emissions DTC, first check the
fuel and emissions system as indicated by the DTC
(except DTC 70, DTC 70 means there is one or more
A/T DTCs, and no problems were detected in the
fuel and emissions circuit of the PCM).
5. Clear the DTC and data.
6. Drive the vehicle for several minutes under the
same conditions as those indicated by the freeze
data, and then recheck for DTCs. If the A/T DTC
returns, go t o the DTC troubleshooting index. If the
DTC does not return, there w a s an intermittent
problem w i t h i n the circuit. Make sure all pins and
terminals in the circuit are tight.

2. Turn the ignition switch OFF.
3. Turn the ignition switch ON (II). Wait 30 seconds.
2. Inspect the circuit at the PCM, according to the DTC
troubleshooting, w i t h the special tools and a digital
multimeter.
3. Connect the backprobe adapters (A) to the stacking
patch cords (B), and connect the cords to a
multimeter (C).
4. Turn the ignition switch OFF, and disconnect the
HDS f r o m the DLC.

This c o m m a n d clears stored specific data f r o m the PCM
such as DTCs freeze data, and readiness codes. It does
not clear CKP PATTERN data.
1. Reset the PCM w i t h the HDS w h e n the engine is
stopped.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON (II), and wait
30 seconds.
4. Turn the ignition switch OFF, and disconnect the
HDS f r o m the DLC.
5. Do the PCM idle learn procedure (see page 11-268).
4. Using the wire insulation as a guide for the
contoured tip of the backprobe adapter, gently slide
the tip into the connector f r o m the wire side until it
touches the end of the wire terminal.
5. If you cannot get to the wire side of the connector
or the wire side is sealed, disconnect the connector

PCM Updating and Substitution f o r Testing
Special Tools Required
• Honda diagnostic system (HDS) TDSGDS2200
- Honda interface module (HIM) EQS05A35570
• HDS pocket tester TDSS3557011401
These special tools are available through the Honda
Tool and Equipment Program 1-888-424-6857
1. Turn the ignition switch ON (II), but do not start the
engine.
2. Connect the HDS to the data link connector (DLC)
(A) located under the driver's side of the dashboard.
Use this procedure w h e n you have to substitute a
known-good PCM or update the PCM in a
troubleshooting procedure.
Updating the PCM
NOTE:
• Make sure the HDS/HIM has the latest software
version.
• Before you update the PCM, make sure the battery in
the vehicle is fully changed.
• Never turn the ignition switch OFF during the update.
If there is a problem w i t h the update, leave the
ignition switch ON.
• To prevent PCM damage, do not operate anything
electrical (headlights, audio system, brakes, A/C,
power w i n d o w s , door locks, etc.) during the update.
• To ensure the latest program is installed, do an PCM
update whenever the PCM is substituted or replaced.
• You cannot update an PCM w i t h a program it already
has. It will only accept a new program.
• If you need to diagnose the Honda interface module
(HIM) because the HIM's red ( # 3 ) lamp came on or
was flashed during the update, leave the ignition
switch in the ON (II) position w h e n you disconnect the
HIM f r o m the data link connector (DLC). This w i l l
prevent PCM damage.
3. Make sure the HDS communicates with the PCM. If
it doesn't, go to the DLC circuit troubleshooting
(see page 11-174). If you are returning f r o m the
DLC circuit troubleshooting, skip steps 4 and 5,
then clean the throttle body after updating the PCM
(see page 11-306).
4. Select the INSPECTION MENU w i t h the HDS.
5. Select the ETCS TEST, then select the TP POSITION
CHECK, and follow the screen prompts with the
HDS.
NOTE: If the TP POSITION CHECK indicates FAILED,
continue this procedure.
6. Exit the HDS diagnostic system, then select the
update mode, and follow the screen prompts to
update the PCM.

7. If the software in the PCM is the latest, disconnect
the HDS/HIM f r o m the DLC, and go back to the
procedure that you were doing. If the software in
the PCM is not the latest, f o l l o w the instructions on
the screen. If prompted to choose the PGM-FI
system or the A/T system, make sure y o u update
both.
NOTE: If the PCM update system requires you to
cool the PCM, f o l l o w the screen prompts. If y o u run
into a problem (programming takes over
15 minutes, status bar goes over 100 %, D or
immobilizer indicator flashes, HDS tablet freezes,
etc.) during the update procedure, f o l l o w these
steps to minimize the chance of damaging the
PCM:
• Leave the ignition switch in the " O N (II)" position.
• Connect a jumper battery (do not connect a
battery charger).
• Shut d o w n the HDS.
• Disconnect the HDS f r o m the HDS.
• Reboot the HDS.
• Reconnect the HDS to the DLC, and try the
update procedure again.
8. If the TP POSITION CHECK failed in step 6, clean
the throttle body (see page 11-306).
9. Do the PCM idle learn procedure (see page 11-268).
(cont'd)
Substituting the PCM
MOTE: Use this procedure w h e n substituting a knowngood PCM during troubleshooting procedures.
1. Connect the HDS to the data link connector (DLC)
(A) located under the driver's side of the dashboard.
2. Turn the ignition switch ON (II).
3. Make sure the HDS communicates w i t h the PCM. If
it doesn't, go to the DLC circuit troubleshooting
(see page 11-174). If you are returning f r o m DLC
circuit troubleshooting, skip steps 4 thru 8, then
clean the throttle body after substituting the PCM
(see page 11-306).
10. Do the CKP learn procedure (see page 11-4).
4. Select the INSPECTION MENU w i t h the HDS.
5. Select the ETCS TEST, then select the TP POSITION
CHECK and f o l l o w the screen prompts.
NOTE: If the TP POSITION CHECK indicates FAILED,
continue this procedure.
6. J u m p the SCS line w i t h the HDS.
14-8
7. Remove the passenger's dashboard under cover
(see page 20-78), the side kick panel (see page
20-52), and the glove box (see page 20-77).
8. Disconnect the connectors (A), and remove the
bolts (B), then remove the PCM (C).
10. Turn the ignition switch ON (II).
NOTE: DTC P0630 " V I N Not Programmed or
M i s m a t c h " may be stored because the VIN has not
been p r o g r a m m e d into the PCM; ignore it, and
continue this procedure.
11. Manually input the VIN to the PCM w i t h the HDS.
12. Update the PCM if it does not have the latest
software.
13. Select the IMMOBI SYSTEM w i t h the HDS.
14. Enter the immobilizer code w i t h the PCM
replacement procedure in the HDS; it allows you to
start the engine.
15. Reset the PCM with the HDS.
16. If the TP POSITION CHECK failed in step 5, clean
the throttle body (see page 11-306).
17. Do the PCM idle learn procedure (see page 11-268).
18. Do the CKP pattern learn procedure (see page 11-4).

S f stem Description
General Operation
The automatic transmission is a combination of a 3-element torque converter and a triple-shaft electronically
controlled unit which provides 5 speeds forward and 1 reverse. The entire unit is positioned in line w i t h the engine.
Torque Converter, Shafts, Gears, and Clutches
The torque converter consists of a pump, turbine, and stator assembly in a single unit. The converter housing (pump)
is connected to the engine crankshaft and turns as the engine runs. Around the outside of the torque converter is a
ring gear which meshes w i t h the starter pinion w h e n the engine is being started. The entire torque converter assembly
serves as a flywheel while transmitting power to the transmission mainshaft. The transmission has three parallel
shafts; the mainshaft, the countershaft and the secondary shaft. The mainshaft is in line w i t h the engine crankshaft,
and includes the 3rd and 5th clutches, and gears for 3rd, 5th, reverse, and idler. The mainshaft reverse gear is integral
w i t h the mainshaft 5th gear. The countershaft includes the gears for 1st, 2nd, 3rd, 4th-5th, reverse, park, and the final
drive. The countershaft 4th-5th gear enables the shared use of the secondary shaft 4th gear and the mainshaft 5th gear.
The countershaft 4th-5th gear and the countershaft reverse gear can be locked to the countershaft providing the 4th,
5th or reverse gear, depending on which way the selector is moved. The final drive gear is integral w i t h the
countershaft. The secondary shaft includes the 1st, 2nd, and 4th clutches, and gears for 1st, 2nd, 4th, and idler. The
idler gear shaft is located between the mainshaft and secondary shaft, and the idler gear transmits power between the
mainshaft and the secondary shaft. The gears on the mainshaft and the secondary shaft are in constant mesh w i t h
those on the countershaft. When certain combinations of gears in the transmission are engaged by the clutches,
power is transmitted through the mainshaft, to the secondary shaft, then to the countershaft to provide drive.
Electronic Control
The electronic control system consists of the powertrain control module (PCM), sensors, and seven solenoid valves.
Shifting and lock-up are electronically controlled for comfortable driving under all conditions. The PCM is located
behind the glove box.
Hydraulic Control
The valve bodies include the main valve body, the regulator valve body, and the servo body. They are bolted to the
torque converter housing. The main valve body contains the manual valve, cut valve B, shift valves A, C, and D, the
relief valve, the lock-up control valve, the cooler check valve, the servo control valve, and the ATF p u m p gears. The
regulator valve body contains the regulator valve, the torque converter check valve, the lock-up shift valve, the 1 st
accumulator, and the 3rd accumulator. The servo body contains the servo valve, shift valve B, cut valve A,
accumulators for 2nd, 4th, and 5th, and shift solenoid valves A, B, C, and D. Fluid f r o m the regulator passes through
the manual valve to the various control valves. The 2nd, 3rd, and 4th clutches receive fluid f r o m their respective feed
pipes, and the 1st and the 5th clutches receive fluid f r o m the internal hydraulic circuit.
Shift Control Mechanism
To shift gears, the PCM controls shift solenoid valves A, B, C, and D, and automatic transmission (A/T) clutch pressure
control solenoid valves A, B, and C, while receiving input signals f r o m various sensors and switches located
throughout the vehicle. The shift solenoid valves shift the positions of the shift valves to switch the port to send
hydraulic pressure to the clutch. The A/T clutch pressure control solenoid valves A, B, and C regulate their respective
pressure, and pressurize to the clutches to engage it and its corresponding gear.
Lock-up Mechanism
The lock-up mechanism operates in the D position or S position in sequential shift mode (2nd, 3rd, 4th, and 5th), and
D3 position or S position in automatic shift mode (2nd and 3rd). The pressurized fluid is drained f r o m the back of the
torque converter through a fluid passage, causing the torque converter clutch piston to be held against the torque
converter cover. As this takes place, the mainshaft rotates at the same speed as the engine crankshaft. Together w i t h
the hydraulic control, the PCM optimizes the t i m i n g and volume of the lock-up mechanism. When shift solenoid valve
D is turned on by the PCM, shift solenoid valve D pressure switches the lock-up shift valve lock-up on and off. The A/T
clutch pressure control solenoid valve A and the lock-up control valve control the amount of lock-up.

Automatic Transmission
S f stem Description (cont'd)
Clutches and Gears
The 5-speed automatic transmission uses hydraulically-actuated clutches to engage or disengage the transmission
gears. When hydraulic pressure is introduced into the clutch d r u m , the clutch piston moves. This presses the friction
discs and steel plates together, locking them so they don't slip. Power is then transmitted through the engaged clutch
pack to its hub-mounted gear. Likewise, when the hydraulic pressure is bled f r o m the clutch pack, the piston releases
the friction discs and steel plates, and they are free to slide past each other. This allows the gear to spin independently
on its shaft, transmitting no power.

Grade Logic Control: Ascending Control
When the PCM determines that the vehicle is climbing a hill in the D, D3, and S positions, the system extends the
engagement area of 2nd gear, 3rd gear, and 4th gear to prevent the transmission f r o m frequently shifting'between
2nd and 3rd gears, between 3rd and 4th gears, and between 4th and 5th gears, so the vehicle can run smooth and

NOTE; Shift commands stored in the PCM between 2nd and 3rd gears, between 3rd and 4th gears, and between 4th
and 5th gears, enable the PCM to automatically select the most suitable gear according to the magnitude of a gradient.

Grade Logic Control; Descending Control
W h e n the PCM determines that the vehicle is going d o w n a hill in the D, D3, and S positions, the shift-up speed f r o m
4th to 5th gear, 3rd to 4th gear, and f r o m 2nd to 3rd (when the throttle is closed) becomes faster than the set speed for
flat road driving to widen the 4th gear, 3rd gear, and 2nd gear engagement areas. This, in combination w i t h engine
braking f r o m the deceleration lock-up, achieves smooth driving w h e n the vehicle is descending. There are three
descending modes w i t h different 4th gear driving areas, 3rd gear driving areas and 2nd gear driving areas according
to the magnitude of a gradient stored in the PCM. When the vehicle is in 5th or 4th gear and you are decelerating while
applying the brakes on a steep hill, the transmission will downshift to a lower gear. When you accelerate, the
transmission will then return to a higher gear.

D-Steering Shift and Sequential Shift Modes - 5-position A u t o m a t i c Transmission
The transmission has t w o manual shift modes; the D-steering shift mode w h e n the shift lever is in the D position, and
the sequential shift mode w h e n the shift lever is in the S position. Both modes are entered by pulling the steering
wheel downshift or upshift switch while driving. The shift indicator, located in the gauge control module, displays the
selected gear number while in the manual shift modes.

D-Steering Shift Mode - 5-position Automatic Transmission
W h e n y o u are driving in the D position, you can manually shift the transmission up and d o w n by pulling the steering
wheel downshift or upshift switch. W h e n you pull either steering wheel shifter switch, the transmission enters the Dsteering shift mode, and the shift indicator shows the current gear number. To shift up or d o w n , pull one of the
steering wheel shifter switches while the transmission is still in the D-steering shift mode (shift indicator on), and the
selected gear number will be displayed on the shift indicator. However, w h e n a lower or higher gear is requested
before engine speed reaches the lower or upper limit for that gear, the transmission will not shift, and the shift
indicator flashes the requested number several times before returning to the original gear. The transmission w i l l stay
in the shift mode if the steering wheel downshift switch is pulled w h e n going downhill and engine braking is being
used. The system monitors the accelerator pedal and the driving conditions, and turns the shift mode and indicator off
w h e n it senses that the driver is driving under normal conditions or w h e n the vehicle comes to a complete stop.
Sequential Shift IVtade - 5-position Automatic Transmission
When you are driving in the S position, you can manually shift the transmission up and d o w n by pulling the steering
wheel downshift or up shift switch. When y o u pull either steering wheel shifter switch, the transmission enters the
sequential shift mode and the shift indicator displays " M " along w i t h the current gear number. The transmission will
no longer automatically shift and must be shifted d o w n or up (before the engine speed reaches the tachometer's red
zone) by pulling the appropriate steering wheel shifter switch the shift indicator will display the selected gear.
However, w h e n a lower or higher limit for that gear, the transmission will not shift, and the shift indicator flashes the
requested number several times before returning to the original gear. W h e n driving in 4th or 5th gear, the
transmission shifts to the lower gear if the vehicle slows d o w n to the programmed speed, or by depressing the brake
pedal. The transmission shifts d o w n to 1st gear w h e n the vehicle comes to a complete stop. The vehicle can start off in
2nd gear by pulling the steering wheel upshift switch while at a stop. The transmission stays in the sequential shift
mode until the shift lever is moved to the D position.

Clutch Pressure Control
-.
The PCM actuates A/T clutch pressure control solenoid valves A, B, and C to control the clutch pressure. W h e n shifting
between gears, the clutch pressure regulated by A/T clutch pressure control solenoid valves A, B, and C engages and
disengages the clutch smoothly.
The PCM receives input signals f r o m the various sensors and switches, processes data, and outputs current to A/T
clutch pressure control solenoid valves A, B, and C.

Lock-up Control
Shift solenoid valve D controls the hydraulic pressure to switch the lock-up shift valve and lock-up ON and OFF. The
PCM actuates shift solenoid valve D and A/T clutch pressure control solenoid valve A to start lock-up. A/T clutch
pressure control solenoid valve A applies and regulates hydraulic pressure to the lock-up control valve to control the
amount of lock-up.
The lock-up mechanism operates in the D or S position in sequential shift mode (2nd, 3rd, 4th, and 5th), and in the D3
or S position (2nd and 3rd).

Regulator Valve
The regulator valve maintains constant hydraulic pressure f r o m the ATF p u m p to the hydraulic control system. While
also furnishing fluid to the lubrication system and torque converter. Fluid f r o m the ATF p u m p flows through B and C.
Fluid entering f r o m B flows through the valve orifice to the A cavity. This pressure of the A cavity pushes the regulator
valve to the spring side, and this movement of the regulator valve uncovers the fluid port to the torque converter and
the relief valve. The fluid flows out to the torque converter and the relief valve, and the regulator valve returns under
spring force. According to the level of the hydraulic pressure through B, the position of the regulator valve changes,
and the amount of fluid f r o m C through the torque converter changes. This operation is continued, maintaining the
line pressure.

Increases in hydraulic pressure according to torque are performed by the regulator valve using stator torque reaction,
The stator shaft is splined to the stator in the torque converter, and its arm end contacts the regulator spring cap.
When the vehicle is accelerating or climbing (torque converter range), stator torque reaction acts on the stator shaft,
and the stator arm pushes the regulator spring cap in the direction of the arrow in proportion to the reaction. The
stator reaction spring compresses, and the regulator valve moves to increase the line pressure which is regulated by
the regulator valve. The line pressure reaches its m a x i m u m w h e n the stator torque reaction reaches its m a x i m u m .

Hydraulic Flow
Distribution of Hydraulic Pressure
As the engine turns, the ATF p u m p starts to operate. Automatic transmission fluid (ATF) is drawn through the ATF
strainer (filter) and discharged into the hydraulic circuit. Then, ATF f l o w i n g f r o m the ATF p u m p becomes line pressure
that is regulated by the regulator valve. Torque converter pressure f r o m the regulator valve enters the torque
converter through the lock-up shift valve, and it is discharged f r o m the torque converter. The torque converter check
valve prevents torque converter pressure f r o m rising.
The PCM controls the shift solenoid valves ON and OFF. The shift solenoid valve blocks line pressure f r o m the ATF
p u m p via the manual valve w h e n the shift solenoid valve is OFF. W h e n the shift solenoid valve is turned ON by the
PCM, line pressure changes to shift solenoid valve pressure at the shift solenoid valve, then the shift solenoid valve
pressure flows to the shift valve. Applying shift solenoid pressure to the shift valve moves the position of the shift
valve, and switches the port of the hydraulic circuit. The PCM also controls A/T clutch pressure control solenoid valves
A, B, and C. The A/T clutch pressure control solenoid valves regulate hydraulic pressure, and apply the pressure to the
clutches to engage smoothly. The clutches receive o p t i m u m clutch pressure w h i c h is regulated by the A/T clutch
pressure control solenoid valves for comfortable driving and shifting under all conditions.

Lock-up System
The lock-up mechanism of the torque converter clutch operates in the D position or S position in sequential shift mode
(2nd, 3rd, 4 t h , and 5 t h ) and D3 position or S position in automatic shift mode (2nd and 3rd). The pressurized fluid is
drained from the back of the torque converter through a fluid passage, causing the torque converter clutch piston to be
held against the torque converter cover. As this takes place, the mainshaft rotates at the same speed as the engine
crankshaft. Together w i t h the hydraulic control, the PCM optimizes the t i m i n g and amount of the lock-up mechanism.
When shift solenoid valve D is turned ON by the PCM, shift solenoid valve D pressure switches the lock-up shift valve
lock-up ON and OFF. A/T clutch pressure control solenoid valve A and the lock-up control valve control the amount of
lock-up.
Torque Converter Clutch Lock-up ON (Engaging Torque Converter Clutch)
Fluid in the chamber between the torque converter cover and the torque converter clutch piston is drained off, and
fluid entering f r o m the chamber between the p u m p and stator exerts pressure through the torque converter clutch
piston against the torque converter cover. The torque converter clutch piston engages w i t h the torque converter cover;
the torque converter clutch lock-up is O N , and the mainshaft rotates at the same speed as the engine.
MAINSHAFT
Torque Converter Clutch Lock-up O F F (Disengaging Torque Converter Clutch)
Fluid entered f r o m the chamber between the torque converter cover and the torque converter clutch piston passes
through the torque converter and goes out f r o m the chambers between the turbine and the stator, and between the
p u m p and the stator. As a result, the torque converter clutch piston moves away f r o m the torque converter cover, and

pressure (94) enters into the back of the torque converter, and discharges into the circuit f r o m the front of the torque
converter. Torque converter pressure enter into back the of the torque converter and is discharged f r o m the front side;
this disengages the torque converter clutch piston and the torque converter cover. Under this condition, the torque

Lock-up S f stem (cont'd)
Partial Lock-up
As the speed of the vehicle reaches the programmed value, the PCM turns shift solenoid valve D ON. Shift solenoid
valve D pressure (SD) is applied to the right end of the lock-up shift valve to switch the torque converter pressure port
leading to the front of the torque converter. Torque converter pressure (91) enters into the front of the torque
converter to engage the torque converter clutch piston. The PCM also controls A/T clutch pressure control solenoid
valve A to regulate A/T clutch pressure control solenoid valve A pressure (55), and A/T clutch pressure control
solenoid valve A pressure (55) is applied to the lock-up control valve. Torque converter pressure (94) drained from the
back of the torque converter is applied to the right side of the lock-up control valve, and torque converter pressure (90)
is applied to the left side of the lock-up control valve. The lock-up control valve controls the amount of the lock-up by
receiving these pressures. The torque converter clutch is engaged partially when torque converter pressure (90) in the
left side of the lock-up control valve is higher, and the torque converter clutch is engaged securely according to the
amount of pressure in the right side of the lock-up control valve. Under this condition, the torque converter clutch is
engaged by pressure entering into the front side of the torque converter; this condition is-partial lock-up.
NOTE: When used, "left" or "right" indicates direction on the hydraulic circuit.

Full Lock-up
. • •
••
. . . . . . .
When the vehicle speed further increases, the PCM controls A/T clutch pressure control solenoid valve A to increase
A/T clutch pressure control solenoid valve A pressure (55). A/T clutch pressure control solenoid valve A pressure (55)
is applied to the lock-up control valve, and the lock-up control valve is moved t o the left side to release torque
converter back pressure (94). Torque converter pressure (91) enters into the front of the torque converter, and the
torque converter clutch piston is securely engaged w i t h the torque converter cover by torque converter pressure.
Under this condition, torque converter back pressure is released fully, causing the torque converter clutch to be fully
engaged; this condition is full lock-up.
NOTE: W h e n used, " l e f t " or " r i g h t " indicates direction on the hydraulic circuit.
