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
[O] 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.

ENGINE CONTROL
SYSTEM OUTLINE
This system utilizes an engine control module and maintains overall control of the engine and so on. An outline of the engine
control is explained here.
1. INPUT SIGNALS
(1) Engine coolant temp. signal circuit
The engine coolant temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance which
varies according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the engine
control module as a control signal.
(2) Intake air temp. signal circuit
The intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as a
control signal to TERMINAL THA of the engine control module.
(3) Oxygen sensor signal circuit
The oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensors
(Bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1) to TERMINALS OX1A, OX1B, OX2A of the engine control module.
To stabilize detection performance by the heated oxygen sensors, the heated oxygen sensors are warmed. This heater
is also controlled by the engine control module (HT1A, HT1B, HT2A).
(4) RPM signal circuit
Camshaft position is detected by the camshaft position sensor and its signal is input to TERMINAL G2 of the engine
control module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor installed in the
cylinder block and the signal is input into TERMINAL NE+ of the engine control module as a control signal.
(5) Throttle signal circuit
The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINAL
VTA of the engine control module.
(6) Vehicle speed circuit
The vehicle speed sensor, installed inside the transmission, detects the vehicle speed and inputs a control signal into
TERMINAL SPD of the engine control module.
(7) A/C SW signal circuit
The operating voltage of the A/C magnetic clutch is detected and the signal is input into TERMINAL ACMG of the engine
control module as a control signal.
(8) Battery signal circuit
Voltage is constantly applied to TERMINAL BATT of the engine control module. With the ignition SW turned on, Voltage
for engine control module start–up power supply is applied to TERMINAL +B of the engine control module via the EFI
MAIN relay.
(9) Intake air volume signal circuit
Intake air volume is detected by the mass air flow meter and the signal is input to TERMINAL VG of the engine control
module as a control signal.
(10) Stop light SW signal circuit
The stop light SW is used to detect whether or not the vehicle is braking and the signal is input into TERMINAL STP of
the engine control module as a control signal.
(11) Starter signal circuit
To confirm whether the engine is cranking, the voltage applied to the starter motor during cranking is detected and the
signal is input into TERMINAL STA of the engine control module as a control signal.
(12) Engine knock signal circuit
Engine knocking is detected by knock sensor and the signal is input into TERMINAL KNK1 as a control signal.

2. CONTROL SYSTEM
∗ SFI system
The SFI system monitors the engine condition through the signals input from each sensor (Input signals from (1) to (12)
etc.) to the engine control module. The best fuel injection timing is decided based on this data and the program
memorized by the engine control module, and the control signal is output to TERMINALS #10, #20, #30 and #40 of the
engine control module to operate the injector (Inject the fuel). The sequential multiport fuel injection (Electronic fuel
injection) system controls the fuel injection operation by the engine control module in response to the driving conditions.
∗ ESA system
The ESA system monitors the engine condition through the signals input to the engine control module from each sensor
(Input signals from (1), (2), (4) to (12) etc.). The best ignition timing is decided according to this data and the memorized
data in the engine control module, and the control signal is output to TERMINALS IGT1, IGT2, IGT3 and IGT4. This
signal controls the igniter to provide the best ignition timing for the driving conditions.
∗ Heated oxygen sensor heater control system
The heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of
exhaust emissions is low), and warms up the heated oxygen sensors (Bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor
1) to improve detection performance of the sensors.
The engine control module evaluates the signals from each sensor (Input signals from (1), (2), (4), (8) to (10) etc.), and
outputs current to TERMINALS HT1A, HT1B, HT2A to control the heater.
3. DIAGNOSIS SYSTEM
With the diagnosis system, when there is a malfunction in the engine control module signal system, the malfunctioning
system is recorded in the memory. The malfunctioning system can be found by reading the code displayed by the
malfunction indicator lamp.
4. FAIL–SAFE SYSTEM
When a malfunction has occurred 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 control module memory or else stops the engine.

WIPER AND WASHER
SYSTEM OUTLINE
With the ignition SW turned on, current flows to TERMINAL 17 of the front wiper and washer SW, TERMINAL 2 of the front
wiper motor through the WIPER fuse and TERMINAL 2 of the washer motor through the WASHER fuse.
1. LOW SPEED POSITION
With the wiper SW turned to LOW position, current flows from TERMINAL 17 of the front wiper and washer SW to
TERMINAL 7 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to GROUND, causing the front wiper motor to run at
low speed.
2. HIGH SPEED POSITION
With the wiper SW turned to HIGH position, current flows from TERMINAL 17 of the front wiper and washer SW to
TERMINAL 8 to TERMINAL 3 of the front wiper motor to TERMINAL 4 to GROUND, causing the front wiper motor to run at
high speed.
3. INT POSITION
With the wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows from
TERMINAL 17 of the front wiper and washer SW to TERMINAL 2 to GROUND. This operates the intermittent circuit and
current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 5 of the front wiper motor
to TERMINAL 4 to GROUND, and operating the wiper.
The intermittent operation is controlled by a condenser’s charged and discharged function installed in the relay, and the
intermittent time is controlled by a time control SW to change the charging time of the condenser.
4. MIST POSITION
With the wiper SW turned to MIST position, current flows from TERMINAL 17 of the front wiper and washer SW to front wiper
mist SW to TERMINAL 2 to GROUND, and current flows from TERMINAL 17 of the front wiper and washer SW to
TERMINAL 7 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to GROUND, causing the front wiper motor to run at
low speed.
5. WASHER CONTINUOUS OPERATION
With the washer SW pushed to on, current flows from TERMINAL 2 of the washer motor to TERMINAL 1 to TERMINAL 11 of
the front wiper and washer SW to TERMINAL 2 to GROUND, causing the washer motor to run, and the window washer
emits a water spray. This causes current to flow to washer continuity operation circuit in TERMINAL 17 of the front wiper and
washer SW to TERMINAL 7 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to GROUND, operating the wiper.

SYSTEM OUTLINE
1. LIGHT REMINDER SYSTEM
When the ignition SW is OFF and the driver’s side door or passenger’s side door is opened (Door courtesy SW ON) and the
light control SW is at TAIL or HEAD position, the light reminder buzzer comes ON.
2. KEY REMINDER BUZZER SYSTEM
If the driver door is opened with the ignition SW set at the ACC or OFF position and the ignition key remained inserted into
the key cylinder (The unlock warning SW is on), the signal from the unlock warning SW is input to TERMINAL KSW of the
body ECU and the signal from the door courtesy SW LH is input to TERMINAL DCTY of body ECU. As a result, through
communication control of the body ECU etc. the buzzer in the combination meter goes on to warn the driver that the ignition
key is still inserted.

SRS
NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following precautionary
instructions and the procedure and precautions in the Repair Manual for the applicable model year.

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.

Work must be started after 90 seconds from when the ignition switch 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 be deployed.)

When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is
finished, reset the audio systems as they were before and adjust the clock. To avoid erasing the memory in each
memory system, never use a back–up power supply from outside the vehicle.

Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs.

Do not expose the steering wheel pad, passenger airbag assembly, seat belt pretensioner, center airbag sensor
assembly, front airbag sensor assembly, directly to hot air or flames.

Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, passenger airbag assembly,
seat belt pretensioner, center airbag sensor assembly, front airbag sensor assembly should be inspected.

Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.

Never disassemble and repair the steering wheel pad, passenger airbag assembly, seat belt pretensioner, center airbag
sensor assembly, front airbag sensor assembly in order to reuse it.

If the steering wheel pad, passenger airbag assembly, seat belt pretensioner, center airbag sensor assembly, front
airbag sensor assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket or
connector, replace them with new ones.

Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system’s electrical circuits.

Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices.

After work on the SRS is completed, perform the SRS warning light check.

If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair
Manual.

SRS
SYSTEM OUTLINE
The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts. When the
ignition SW is turned to ACC or ON, the current from the SRS fuse flows to the center airbag sensor assembly TERMINAL
(B) 6. Only when the ignition SW is ON does the current from the IGN fuse flow to center airbag sensor assembly
TERMINAL (B) 5.
In case an accident occurs while driving, when the frontal impact exceeds a predetermined level, the current from the center
airbag sensor assembly TERMINAL (B) 14 to airbag squibs TERMINAL 1 to TERMINAL 2 to center airbag sensor assembly
TERMINAL (B) 13 to TERMINAL (B) 27, (B) 28 to GROUND or BODY GROUND. The current flows to the airbag squibs,
and the airbag stored in the steering wheel is expanded instantaneously to reduce the impact to the driver.
As for the passenger side seat, if the passenger airbag manual ON/OFF SW is on, the current flows from the center airbag
sensor assembly TERMINAL (B) 10 to passenger airbag manual SW ON/OFF SW TERMINAL (B) 1 to TERMINAL (B) 2 to
airbag squibs TERMINAL 2 to TERMINAL 1 to passenger airbag manual SW ON/OFF SW TERMINAL (B) 3 to TERMINAL
(B) 4 to center airbag sensor assembly TERMINAL (B) 11 to TERMINAL (B) 27, (B) 28 to GROUND or BODY GROUND.
The airbag stored in the front passenger’s instrument panel is expanded instantaneously to reduce the impact to the front
passenger.

ABS
SYSTEM OUTLINE
This system controls the respective brake fluid pressures acting on the brake cylinders of the right front wheel, the left front
wheel, the right rear wheel and the left rear wheel 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 SIGNALS
(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the ABS ECU.
(2) Stop light SW signal
A signal is input to TERMINAL STP of the ABS ECU when the brake pedal depressed.
2. SYSTEM OPERATION
During sudden braking the ABS ECU which has signals input from each of the sensor, controls current to the solenoid inside
the actuator and causes the hydraulic pressure acting on each of the wheel cylinder escape to the reservoir. The pump
inside the actuator is also operating at this time and it returns the brake fluid from the reservoir to the master cylinder,
preventing locking of the vehicle wheels.
If the ECU 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.

SYSTEM OUTLINE
1. HEATER BLOWER MOTOR OPERATION
Current is applied at all times through the HTR fuse to TERMINAL 5 of the HTR relay.
When the ignition SW is turned on, the current flows through HTR fuse to TERMINAL 1 of the HTR relay to TERMINAL 2 to
TERMINAL 8 of the blower SW.

∗ Low speed operation

When the blower SW is moved to LO position, the current flows the to TERMINAL 8 of the blower SW to TERMINAL 1 to
GROUND, causing the HTR relay to turn on. This causes the current to flow from the HTR fuse to TERMINAL 5 of the
HTR relay to TERMINAL 3 to TERMINAL 1 of the blower motor to TERMINAL 2 to TERMINAL 1 of the blower resistor to
TERMINAL 4 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 8 of the blower SW to TERMINAL 1 to
GROUND, causing the HTR relay to turn on. This causes the current flows from the HTR fuse to TERMINAL 5 of the
HTR relay to TERMINAL 3 to TERMINAL 1 of the blower motor to TERMINAL 2 to TERMINAL 1 of the blower resistor to
TERMINAL 2 to TERMINAL 6 of the blower SW to TERMINAL 1 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 through the motor flows from TERMINAL 1 of the blower
resistor to TERMINAL 3 to TERMINAL 5 of the blower SW to TERMINAL 1 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 8 of the blower SW to TERMINAL 1 to
GROUND, causing the HTR relay to turn on.
This causes the current to flow from the HTR fuse to TERMINAL 5 of the heater relay to TERMINAL 3 to TERMINAL 1 of
the blower motor to TERMINAL 2 to TERMINAL 3 of the blower SW to TERMINAL 1 to GROUND, rotating the blower
motor at high speed.
