HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles by
dividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the power
source is received from the battery as far as each ground point. (All circuit
diagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuit
where the problem was detected (see System Circuit section), the power source
supplying power to that circuit (see Power Source section), and the ground points
(see Ground Point section). See the System Outline to understand the circuit
operation.
When the circuit operation is understood, begin troubleshooting of the problem
circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing
sections to find each part, junction block and wiring harness connectors, wiring
harness and wiring harness connectors, splice points, and ground points of each
system circuit. Internal wiring for each junction block is also provided for better
understanding of connection within a junction block.
Wiring related to each system is indicated in each system circuit by arrows
(from__, to__). When overall connections are required, see the Overall Electrical
Wiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL
[N]
System Outline
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows
through the rear lights warning light to TERMINAL 4 of the light failure sensor.
Stop Light Disconnection Warning
When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current
flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the
disconnection and the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights
warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning
circuit on and holds the warning light on until the ignition SW is turned off.

E GLOSSARY OF TERMS AND SYMBOLS
GROUND
The point at which wiring attaches to
the Body, thereby providing a return
path for an electrical circuit; without a
ground, current cannot flow.
BATTERY
Stores chemical energy and
converts it into electrical energy.
Provides DC current for the auto’s
various electrical circuits.
CAPACITOR (Condenser)
A small holding unit for temporary
storage of electrical voltage.
CIGARETTE LIGHTER
An electric resistance heating
element.
HEADLIGHTS
Current flow causes a headlight
1. SINGLE
FILAMENT filament to heat up and emit light. A
headlight may have either a single
(1) filament or a double (2) filament
2. DOUBLE
FILAMENT
CIRCUIT BREAKER
Basically a reusable fuse, a circuit
breaker will heat and open if too
much current flows through it.
Some units automatically reset when
cool, others must be manually reset.
HORN
An electric device which sounds a
loud audible signal.
DIODE
A semiconductor which allows
current flow in only one direction.
IGNITION COIL
Converts low–voltage DC current
into high–voltage ignition current for
firing the spark plugs.
DIODE, ZENER
LIGHT
Current flow through a filament
causes the filament to heat up and
emit light.
A diode which allows current flow in one
direction but blocks reverse flow only up
to a specific voltage. Above that potential,
it passes the excess voltage. This acts as
a simple voltage regulator.
PHOTODIODE
The photodiode is a semiconductor
which controls the current flow
according to the amount of light.
LED (LIGHT EMITTING DIODE)
Upon current flow, these diodes emit
light without producing the heat of a
comparable light.
DISTRIBUTOR, IIA
Channels high–voltage current from
the ignition coil to the individual
spark plugs.
METER, ANALOG
Current flow activates a magnetic
coil which causes a needle to move,
thereby providing a relative display
against a background calibration.
FUSE
METER, DIGITAL
Current flow activates one or many
LED’s, LCD’s, or fluorescent
displays, which provide a relative or
digital display.
A thin metal strip which burns through
when too much current flows through it,
thereby stopping current flow and
protecting a circuit from damage.
FUEL
FUSIBLE LINK
(for Medium Current Fuse)
(for High Current Fuse or
Fusible Link)
18
A heavy–gauge wire placed in high
amperage circuits which burns through on
overloads, thereby protecting the circuit.
The numbers indicate the crosssection
surface area of the wires.
M
MOTOR
A power unit which converts
electrical energy into mechanical
energy, especially rotary motion.
E
RELAY
Basically, an electrically operated
1. NORMALLYswitch which may be normally
CLOSED closed (1) or open (2).
Current flow through a small coil
creates a magnetic field which either
opens or closes an attached switch.
2. NORMALLY
OPEN
RELAY, DOUBLE THROW
A relay which passes current
through one set of contacts or the
other.
SPEAKER
An electromechanical device which
creates sound waves from current
flow.
SWITCH, MANUAL
Opens and closes
circuits, thereby
1. NORMALLY
stopping (1) or
OPEN
allowing (2) current
flow.
2. NORMALLY
CLOSED
RESISTOR
An electrical component with a fixed
resistance, placed in a circuit to
reduce voltage to a specific value.
SWITCH, DOUBLE THROW
A switch which continuously passes
current through one set of contacts
or the other.
RESISTOR, TAPPED
A resistor which supplies two or
more different non adjustable
resistance values.
SWITCH, IGNITION
A key operated switch with several
positions which allows various
circuits, particularly the primary
ignition circuit, to become
operational.
RESISTOR, VARIABLE or RHEOSTAT
A controllable resistor with a variable
rate of resistance.
Also called a potentiometer or
rheostat.
(Reed Switch Type)
SENSOR (Thermistor)
A resistor which varies its resistance
with temperature.
SWITCH, WIPER PARK
Automatically returns wipers to the
stop position when the wiper switch
is turned off.
SENSOR, SPEED
Uses magnetic impulses to open
and close a switch to create a signal
for activation of other components.
TRANSISTOR
A solidstate device typically used as
an electronic relay; stops or passes
current depending on the voltage
applied at ”base”.
SHORT PIN
Used to provide an unbroken
connection within a junction block.
SOLENOID
An electromagnetic coil which forms
a magnetic field when current flows,
to move a plunger, etc.
WIRES
Wires are always drawn as
(1) NOT
straight lines on wiring
CONNECTED diagrams.
Crossed wires (1) without a
black dot at the junction are
not joined;
crossed wires (2) with a
black dot or octagonal ( )
(2) SPLICED
mark at the junction are
spliced (joined)
connections.

System Outline
This system utilizes an engine ECU and maintains overall control of the engine, transmission and so on. An outline of the
engine control is explained here.
1. Input Signals
(1) Water temp. signal circuit
The water temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance varies
according to the engine coolant temp. Thus the engine coolant temp. is input in the form of a control signal to
TERMINAL THW of the engine ECU.
(2) Intake air temp. signal circuit
The intake air temp. sensor is detects the intake air temp. of air cleaner, which is input as a control signal to TERMINAL
THA of the engine ECU.
The intake air temp. sensor is detects the intake air temp. of inter cooler, which is input as a control signal to TERMINAL
THIA of the engine ECU.
(3) RPM signal circuit
Camshaft position and crankshaft position are detected by the camshaft position sensor and crankshaft position sensor.
Camshaft position is input as a control signal to TERMINAL G+ of the engine ECU, and engine RPM is input into
TERMINAL NE+.
(4) Throttle signal circuit
The accelerator position sensor detects the accelerator pedal opening angle, which is input as a control signal to
TERMINALS VPA and VPA2 of the engine ECU.
(5) Vehicle speed signal circuit
The speed sensor detects the vehicle speed and inputs a control signal to TERMINAL SPD of the engine ECU via the
combination meter.
(6) Battery signal circuit
Voltage is constantly applied to TERMINAL BATT of the engine ECU. When the ignition SW is turned to on, voltage for
engine ECU operation is applied via the MAIN relay to TERMINAL +B of the engine ECU.
(7) Started signal circuit
To confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input as
a control signal to TERMINAL STA of the engine ECU.
(8) Fuel temp. signal circuit
The fuel temp. sensor is detects the fuel temp., which is input as a control signal to TERMINAL THF of the engine ECU.
(9) Intake air vacuum pressure signal system
Intake air vacuum pressure is detected by the turbo pressure sensor and is input as a control signal to TERMINAL PIM
of the engine ECU.
75
Engine Control
2. Control System
∗ EGR control
The EGR control system detects the signals from each sensor, then the current is output to the TERMINAL EGR to control
the VRV (EGR).
∗ Common rail pressure control
The target rail pressure is calculated according to the engine status (Accelerator opening, engine speed) and
environmental change detected by sensors. The fuel amount to be pressure–fed from the supply pump is calculated so as
to match the indicated value of rail pressure sensor with the target value and the signal is sent to the intake amount
adjusting valve of the supply pump in order to control the rail pressure.
∗ Fuel injection timing control
The fuel injection timing is controlled by calculating the basic fuel injection timing based on the engine status (Accelerator
opening, engine speed), making corrections according to environmental change detected by sensors, then sending a
signal to the solenoid control valve of the injector via the injector driver (EDU).
∗ Fuel injection volume control
The fuel injection volume is controlled by calculating the basic fuel injection volume based on the engine status
(Accelerator opening, engine speed), making corrections according to environmental change detected by sensors and the
inside pressure conditions in the rail, then sending a signal to the solenoid control valve of the injector via the injector
driver (EDU).
∗ Pilot injection control
The fuel injection volume and timing are controlled by calculating the pilot injection volume/timing based on the engine
status (Accelerator opening, engine speed), making corrections according to environmental change detected by sensors,
then sending a signal to the solenoid control valve of the injector via the injector driver (EDU).
3. Diagnosis System
With the diagnosis system, when there is a malfunctioning in the engine ECU signal system, the malfunction system is
recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the check engine warning
light.
4. Fail–Safe System
When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control based
on the signals from that system, the fail–safe system either controls the system by using data (Standard values) recorded in
the engine ECU memory or else stops the engine.

System Outline
The current is applied at all times to TERMINAL 1 of the combination meter through the DOME fuse.
When the ignition SW is turned to ON position, the current flows to TERMINAL 21 of the combination meter through the MET
fuse. When the light control SW is turned to TAIL or HEAD position, current is applied to TERMINAL 8 of the combination
meter through the TAIL fuse.
1. Key Reminder System
When the driver door is opened with the ignition SW off and ignition key remaining in the key cylinder (Unlock warning SW
on), a signal is input from the unlock warning SW to TERMINAL 10 of the combination meter, and from the door courtesy SW
(Driver’s side) to TERMINAL 16 of the combination meter. As a result, the buzzer in the combination meter goes on and
warns the driver that the key is remaining in the key cylinder.
2. Light Reminder System
When the light control SW is in TAIL or HEAD position, the ignition SW turned to OFF from ON position, ignition key is not in
the key cylinder and the driver’s door opened (Door courtesy SW on), the current flows to TERMINAL 21 of the combination
meter stops. As a result, the combination meter is activated and current flows from TERMINAL 1 of the combination meter,
the buzzer in the combination meter goes on to remind the light is lighting up.

System Outline
Previous automatic transmissions have selected each gear shift using mechanically controlled throttle hydraulic pressure,
governor hydraulic pressure and lock–up hydraulic pressure. The electronically controlled transmission, however, electrically
controls the line pressure, throttle pressure, lock–up pressure and accumulator pressure etc. through the solenoid valve. The
electronically controlled transmission is a system which precisely controls gear shift timing and lock–up timing in response to
the vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth driving possible by
shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing,
squat and gear shift shock when starting off.
1. Lock–Up Operation
When the transmission control ECU decides based on each signal that the lock–up condition has been met, the current
flows through TERMINAL SL of the transmission control ECU to TERMINAL 7 of the ECT solenoid to GROUND, causing
lock–up operation.
2. Stop Lamp SW Circuit
If the brake pedal is depressed (Stop lamp SW on) when driving in lock–up condition, a signal is input to TERMINAL STP of
the transmission control ECU. The transmission control ECU operates and cuts the current to the solenoid to release
lock–up.

System Outline
This system controls the respective brake fluid pressures acting on the brake cylinders of the right front wheel, left front
wheel, and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock.
This results in improved directional stability and steerability during panic braking.
1. Input Signal
(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the skid control ECU with
actuator.
(2) Stop lamp SW signal
A signal is input to TERMINAL STP of the skid control ECU with actuator when the brake pedal is depressed.
2. System Operation
During sudden braking, the skid control ECU with actuator which has signals input from each sensor lets the hydraulic
pressure acting on each wheel cylinder escape to the reservoir.
The pump inside the skid control ECU with actuator is also operating at this time and it returns the brake fluid from the
reservoir to the master cylinder, thus preventing locking of vehicle wheels.
If the skid control ECU with actuator judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current
acting on the solenoid is controlled and the hydraulic pressure is increased.
Holding of the hydraulic pressure is also controlled by the ECU, by the same method as above, by repeated pressure
reduction. Holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking.

SRS
NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructions
and the procedure, and precautions in the Repair Manual applicable for the model year.
D Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information
when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.
D Work must be started more than 90 seconds after the ignition SW is turned to the ”LOCK” position and the
negative (–) terminal cable is disconnected from the battery.
(The SRS is equipped with a back–up power source so that if work is started within 90 seconds from
disconnecting the negative (–) terminal cable of the battery, the SRS may deploy.)
D When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
cleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,
reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power
telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.
However, it is not possible to make a record of these memory contents. So when the work is finished, it will be
necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoid
erasing the memory in each system, never use a back–up power supply from outside the vehicle.
D Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.
D Do not expose the following parts directly to hot air or flame;
D Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;
D Never use SRS parts from another vehicle. When replacing parts, replace with new parts.
D For the purpose of reuse, never disassemble and repair the following parts.
D If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,
replace with new one.
D Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.
D Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.
D After work on the SRS is completed, check the SRS warning light.
D If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair
Manual.

System Outline
The SRS is a driver protection device which has a supplemental role to the seat belts.
When the ignition SW is turned to ON, the current from the ignition SW flows to TERMINAL 21 of the airbag sensor assembly
center.
If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the ignition SW flows to
TERMINAL 5 of the airbag sensor assembly center to the airbag squibs TERMINAL 6 of the airbag sensor assembly center
to TERMINAL 25, 26 or BODY GROUND to GROUND, so that current flows to the airbag squibs and causes them to
operate.
The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.

System Outline
Driving mode is switched to H2 or H4 or L4 when the driver operates the transfer shift lever. Transfer indicator SW (4WD
position) is turned on when the transfer shift lever is shifted in 4WD (H4 or L4).
1. 2-4 Select System
(1) Shifting from H4 to H2
When the transfer shift lever is changed from H4 to H2 position, transfer indicator SW (4WD position) detects OFF signal
to activate the ADD motor, which results in changing the transfer to 2WD (H2 position).
At this time, the transfer indicator SW (4WD position) are off.
(2) Shifting from H2 to H4
When the transfer shift lever is changed from H2 to H4 position, transfer indicator SW (4WD position) detects ON signal
to activate the ADD motor, which results in changing the transfer to 4WD (H4 position) to light up 4WD indicator.
(3) Shifting from H4 to L4
When the transfer shift lever is changed from H4 to L4 position, the shift fork shaft moves to change the transfer to 4WD
(L4 position), which results in turning ON transfer indicator SW (L4 position). ADD motor does not operate since it is only
the lever operation.
(4) Shifting from L4 to H4
When the transfer shift lever is changed from L4 to H4 position, the shift fork shaft moves. When transfer indicator SW
(L4 position) is turned OFF, the transfer changes to 4WD (H4 position). ADD motor does not operate since it is only the
lever operation.
2. Other Control
When abnormality is found in the 4WD system, the driver is warned by 4WD indicator light’s flashing.

When the ignition SW is turned to ACC position the current from the ACC fuse flows to TERMINAL 6 of the shift lock control
ECU. When the ignition SW is turned to ON position, the current from the ECU–IG&GAUGE fuse flows to TERMINAL 1 of
the shift lock control ECU.
1. Shift Lock Mechanism
If the brake pedal is depressed with the ignition SW set at ON (The stop lamp SW is on), the shift lock control ECU is
activated, allowing the driver to change the shift lever to a position other than the P position.
2. Key Interlock Mechanism
With the ignition SW at ON or ACC position, when the shift lever is put in P position, the current flowing from TERMINAL 12
of the shift lock control ECU to key interlock solenoid is cut off. This causes the key interlock solenoid to turn off (Lock lever
disengages from LOCK position) and the ignition key can be turned from ACC to LOCK position.

System Outline
1. Manual Lock Operation
When the door lock control SW or driver’s side door key lock and unlock SW (When driver’s seat belt is unfastened) are
operated to LOCK position, a lock signal is input to TERMINAL 14 of the integration relay and causes the integration relay to
function. The current flows from TERMINAL 5 of the integration relay to TERMINAL 3 to the door lock motors to TERMINAL
2 of the integration relay to TERMINAL 1 to GROUND and the door lock motors locks the door.
2. Manual Unlock Operation
When the door lock control SW or driver’s side door key lock and unlock SW (When driver’s seat belt is unfastened) are
operated to UNLOCK position, an unlock signal is input to TERMINAL 11 of the integration relay and causes the integration
relay to function. The current flows from TERMINAL 5 of the integration relay to TERMINAL 2 to the door lock motors to
TERMINAL 3 of the integration relay to TERMINAL 1 to GROUND and the door lock motors unlocks the door.
3. Speed–Sensitive Automatic Door Lock
Under the precondition that one of the doors is opened with the ignition SW OFF, the theft warning ECU outputs lock signal
to the integration relay and the relay sends the lock signal to all the door lock motors when all the flowing conditions are
satisfied.
∗ All the door are shut.
∗ The unlock warning SW is ON besides the ignition SW is ON.
∗ The vehicle speed reaches about 25km/h.
4. Ignition SW Linked Automatic Door Unlock
Under the precondition that the unlock warning SW is ON as well as the ignition SW is ON after door locked by the
speed–sensitive automatic door lock, the theft warning ECU outputs unlock signal to the integration relay and the relay
sends the unlock signal to all the door lock motor when all the flowing conditions are satisfied.
∗ The unlock warning SW is ON.
∗ The ignition SW is OFF.

System Outline
Door lock control (Lock and unlock) and panic control (Theft alarm and flash) is performed by remote control, without the
ignition key inserted in the door key cylinder, using low–power electrical waves emitted by a transmitter.
1. Normal Operation
∗ Lock operation
When the lock button on the transmitter is pressed, all the doors are locked.
∗ Unlock operation
When the unlock button on the transmitter is pressed, all the doors are locked.
2. Visual Confirmation of Lock or Unlock
If all doors indicate that they are locked after the lock command, security horn sound and hazard lights will sound and flash
once. If any door indicates that it is open after the unlock command, theft deterrent horn sound and hazard lights will sound
and flash twice.
3. Automatic Lock Operation
All the doors are automatically relocked unless any door is opened within 15 seconds after pushing the button (Transmitter)
to unlock all the doors under conditions that the ignition key is not inserted into the ignition key cylinder (Unlock warning SW
off), ignition SW is at OFF and all the doors are completely closed.
4. Illuminated Entry Function
When pushing the unlock button (Transmitter), it turns on the lights, such as the ignition key cylinder lamp for approx. 30
seconds. If the doors are locked with lock button (Transmitter) during this operation and ignition key is in the ignition key
cylinder (Unlock warning SW ON) to turn ON the ignition SW, lighting is cancelled and the lights immediately fade out.
5. Panic Alarm Operation
When the panic button on the transmitter is pushed, alarm sound and flash starts. The panic alarm operation is canceled
when one of the lock button, unlock button and panic alarm button is pressed.
6. Door Ajar Warning (By Pushing Wireless Lock Button)
Half–shut door is warned with security horn sound (For 1 second) by pushing the lock button (Transmitter) when one of the
doors is not completely shut.

Power Window
System Outline
1. Manual Down or Up Operation
When the power window master SW is pushed one step, the motor rotates to open the window.
When the power window master SW is pulled up one step, the motor rotates in the opposite direction, to close the window.
All the other windows can be opened/closed as well, by the operation of the power window master SW or respective power
window SW.
When the window lock SW is pushed to the lock side, the ground circuit to the passenger’s window becomes open. As a
result, even if Open/Close operation of the passenger’s window is attempted, the current from TERMINAL E of the power
window master SW is not grounded and the motor does not rotate, so the passenger’s window can not be operated and
window lock occurs.
2. Auto Down Operation (Driver’s Window)
When the power window master SW is pushed two steps, the motor rotates to open the window automatically.
3. Stopping of Auto Down Operation (Driver’s Window)
Auto operation can be stopped in mid–course with switching power window master SW one step upward during the down
operation.
Service Hints

System Outline
With the ignition SW turned on, the current flows to TERMINAL (B) 3 of the front wiper and washer SW, TERMINAL 1 of the
windshield washer motor and TERMINAL 2 of the windshield wiper motor through the WIP fuse.
1. Low Speed Position
With the front wiper SW turned to LO position, the current flows from TERMINAL (B) 3 of the front wiper and washer SW to
TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to TERMINAL 4 to GROUND and causes the windshield
wiper motor to run at low speed.
2. High Speed Position
With the front wiper SW turned to HI position, the current flows from TERMINAL (B) 3 of the front wiper and washer SW to
TERMINAL (B) 1 to TERMINAL 3 of the windshield wiper motor to TERMINAL 4 to GROUND and causes the windshield
wiper motor to run at high speed.
3. INT Position
With the front wiper SW turned to INT position, the wiper relay operates and current flows from TERMINAL (B) 3 of the front
wiper and washer SW to TERMINAL (A) 2 to GROUND. This activates the intermittent circuit and the current flows from
TERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to
TERMINAL 4 to GROUND and the wiper operates.
The intermittent operation is controlled by the charge/discharge function of the condenser installed in the relay, and the
intermittent time is controlled by a time control SW to change the charging time of the condenser (w/ INT time SW).
Intermittent operation is controlled by a condenser charge and discharge function in the relay (w/o INT time SW).
4. Mist Position
With the front wiper SW turned to MIST position, the current flows from TERMINAL (B) 3 of the front wiper and washer SW to
TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to TERMINAL 4 to GROUND and causes the windshield
wiper motor to run at low speed.
5. Washer Interlocking Operation
With the washer SW pulled to ON position, the current flows from the WIP fuse to TERMINAL 1 of the windshield washer
motor to TERMINAL 2 to TERMINAL (A) 1 of the front wiper and washer SW to TERMINAL (A) 2 to GROUND and causes
the windshield washer motor to run and the window washer to spray. Simultaneously, current flows from the WIP fuse to
TERMINAL (B) 3 of the front wiper and washer SW to TERMINAL (B) 2 to TERMINAL 5 of the windshield wiper motor to
TERMINAL 4 to GROUND, causing the wiper to function.

System Outline
Current is applied at all times through the FR HTR fuse to TERMINAL 5 of the HTR relay.
When the ignition SW is turned on, the current flows through the ECU–IG&GAUGE fuse to TERMINAL 1 of the HTR relay to
TERMINAL 2 to TERMINAL 6 of the blower SW.
Blower Motor Operation
∗ Low speed operation
When the blower SW is moved to LO position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to
GROUND, causing the HTR relay to turn on. This causes the current flows from the FR HTR fuse to TERMINAL 5 of the
HTR relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower resistor to
TERMINAL 1 to GROUND, rotating the blower motor at low speed.
∗ Medium speed operation (Operation at M1, M2)
When the blower SW is moved to M1 position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to
GROUND, causing the HTR relay to turn on. This causes the current flows from the FR HTR fuse to TERMINAL 5 of the
HTR relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower resistor to
TERMINAL 3 to TERMINAL 2 of the blower SW to TERMINAL 5 to GROUND. At this time, the blower resistance of the
blower resistor is smaller than at low speed, so the blower motor rotates at medium low speed.
When the blower SW is moved to M2 position, the current flows through the HTR relay to TERMINAL 2 of the blower
motor to TERMINAL 1 to TERMINAL 4 of the blower resistor to TERMINAL 2 to TERMINAL 1 of the blower SW to
TERMINAL 5 to GROUND. At this time, resistance of the blower resistor is smaller than at M1 position, so the blower
motor rotates at medium high speed.
∗ High speed operation
When the blower SW is moved to HI position, the current flows to TERMINAL 6 of the blower SW to TERMINAL 5 to
GROUND, causing the HTR relay to turn on.
This causes the current flows from the FR HTR fuse to TERMINAL 5 of the HTR relay to TERMINAL 3 to TERMINAL 2
of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower SW to TERMINAL 5 to GROUND, rotating the blower
motor at high speed.
