3. General Description
8) Use the ECM mounting stud bolt at the body
head grounding points when measuring voltage
and resistance inside the passenger compartment.
A: CAUTION
1) Airbag system wiring harness is routed near the
engine control module (ECM), main relay and fuel
pump relay.
CAUTION:
• All airbag system wiring harness and connectors are colored yellow. Do not use electrical test equipment on these circuit.
• Be careful not to damage the airbag system
wiring harness when servicing the engine control module (ECM), transmission control module (TCM), main relay and fuel pump relay.
2) Never connect the battery in reverse polarity.
• The ECM will be destroyed instantly.
• The fuel injector and other part will be damaged
in just a few minutes more.
3) Do not disconnect the battery cables while the
engine is running.
• A large counter electromotive force will be generated in the alternator, and this voltage may damage
electronic parts such as ECM, etc.
4) Before disconnecting the connectors of each
sensor and the ECM, be sure to turn the ignition
switch to OFF.
5) Poor contact has been identified as a primary
cause of this problem. To measure the voltage and/
or resistance of individual sensors or all electrical
control modules at the harness side connector, use
a tapered pin with a diameter of less than 0.64 mm
(0.025 in). Do not insert the pin more than 5 mm
(0.20 in) into the part.
6) Before removing the ECM from located position,
disconnect two cables on battery.
• Otherwise, the ECM may be damaged.
(A)
EN-00069
(A) Stud bolt
9) Use the engine grounding terminal or engine
proper as the grounding point to the body, when
measuring voltage and resistance in the engine
compartment.
EN-00070
10) Use the TCM mounting stud bolts at the body
head grounding point, when measuring voltage and
resistance inside the passenger compartment.
CAUTION:
When replacing the ECM, be careful not to use
the wrong spec. ECM to avoid any damage on
the fuel injection system.
7) The connectors to each sensor in the engine
compartment and the harness connectors on the
engine side and body side are all designed to be
waterproof. However, it is still necessary to take
care not to allow water to get into the connectors
when washing the vehicle, or when servicing the
vehicle on a rainy day.
(A)
EN-00071
(A) Stud bolt
11) Every MFI-related part is a precision part. Do
not drop them.
12) Observe the following cautions when installing
a radio in MFI equipped models.
CAUTION:
• The antenna must be kept as far apart as possible from the control unit.
EN(TURBO)-6
GENERAL DESCRIPTION
ENGINE (DIAGNOSTICS)
(The ECM is located under the steering column,
inside of the instrument panel lower trim panel.)
• The antenna feeder must be placed as far
apart as possible from the ECM and MFI harness.
• Carefully adjust the antenna for correct
matching.
• When mounting a large power type radio, pay
special attention to the three items above mentioned.
• Incorrect installation of the radio may affect
the operation of the ECM.
13) Before disconnecting the fuel hose, disconnect
the fuel pump connector and crank the engine for
more than 5 seconds to release pressure in the fuel
system. If the engine starts during this operation,
run it until it stops.
14) Problems in the electronic-controlled automatic
transmission may be caused by failure of the engine, the electronic control system, the transmission proper, or by a combination of these. These
three causes must be distinguished clearly when
performing diagnostics.
15) Diagnostics should be conducted by rotating
with simple, easy operations and proceeding to
complicated, difficult operations. The most important thing in diagnostics is to understand the customer's complaint, and distinguish between the
three causes.
16) On ABS vehicle, when performing driving test
in jacked-up or lifted-up position, sometimes the
warning light may be lit, but this is not a malfunction
of the system. The reason for this is the speed difference between the front and rear wheels. After diagnosis of engine control system, perform the ABS
memory clearance procedure of self-diagnosis system.
B: INSPECTION
Before performing diagnostics, check the following
items which might affect engine problems:
1. BATTERY
1) Measure the battery voltage and specific gravity
of electrolyte.
Standard voltage: 12 V
Specific gravity: Above 1.260
2) Check the condition of the main and other fuses,
and harnesses and connectors. Also check for
proper grounding.
2. ENGINE GROUNDING
Make sure the engine grounding terminal is properly connected to the engine.
EN-00070
C: NOTE
1. DESCRIPTION
• The on-board diagnostics (OBD) system detects
and indicates a fault in various inputs and outputs
of the complex electronic control. CHECK ENGINE
malfunction indicator lamp (MIL) in the combination
meter indicates occurrence of a fault or trouble.
• Further, against such a failure or sensors as may
disable the drive, the fail-safe function is provided
to ensure the minimal driveability.
• The OBD system incorporated with the vehicles
within this engine family complies with Section
1968.1, California Code of Regulations (OBD-II
regulation). The OBD system monitors the components and the system malfunction listed in Engine
Section which affects on emissions.
• When the system decides that a malfunction occurs, MIL illuminates. At the same time of the MIL illumination or blinking, a diagnostic trouble code
(DTC) and a freeze frame engine conditions are
stored into on-board computer.
• The OBD system stores freeze frame engine
condition data (engine load, engine coolant temperature, fuel trim, engine speed and vehicle
speed, etc.) into on-board computer when it detects
a malfunction first.
• If the OBD system detects the various malfunctions including the fault of fuel trim or misfire, the
OBD system first stores freeze frame engine conditions about the fuel trim or misfire.
• When the malfunction does not occur again for
three consecutive driving cycles, MIL is turned off,
but DTC remains at on-board computer.
• The OBD-II system is capable of communication
with a general scan tool (OBD-II general scan tool)
formed by ISO 9141 CARB.
• The OBD-II diagnostics procedure is different
from the usual diagnostics procedure. When troubleshooting OBD-II vehicles, connect Subaru Select Monitor or the OBD-II general scan tool to the
vehicle.
EN(TURBO)-7
GENERAL DESCRIPTION
ENGINE (DIAGNOSTICS)
2. ENGINE AND EMISSION CONTROL SYSTEM
• The Multipoint Fuel Injection (MFI) system is a
system that supplies the optimum air-fuel mixture
to the engine for all the various operating conditions through the use of the latest electronic technology.
With this system fuel, which is pressurized at a constant pressure, is injected into the intake air passage of the cylinder head. The injection quantity of
fuel is controlled by an intermittent injection system
where the electro-magnetic injection valve (fuel injector) opens only for a short period of time, depending on the quantity of air required for one cycle
of operation. In actual operation, the injection quantity is determined by the duration of an electric
pulse applied to the fuel injector and this permits
simple, yet highly precise metering of the fuel.
• Further, all the operating conditions of the engine
are converted into electric signals, and this results
in additional features of the system, such as large
improved adaptability, easier addition of compensating element, etc.
The MFI system also has the following features:
• Reduced emission of harmful exhaust gases.
• Reduced in fuel consumption.
• Increased engine output.
• Superior acceleration and deceleration.
• Superior startability and warm-up performance in cold weather since compensation is
made for coolant and intake air temperature.
