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 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.

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

FUSIBLE LINK

FUSIBLE LINK

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.

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.

DIODE

A semiconductor which allows
current flow in only one direction.

1. SINGLE
FILAMENT

2. DOUBLE
FILAMENT

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.

HEADLIGHTS

Current flow causes a headlight
filament to heat up and emit light. A
headlight may have either a single
(1) filament or a double (2) filament

HORN

An electric device which sounds a
loud audible signal.

IGNITION COIL

Converts low–voltage DC current
into high–voltage ignition current for
firing the spark plugs.

(for Medium Current Fuse)

(for High Current Fuse or
Fusible Link)

DIODE, ZENER

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.

DISTRIBUTOR, IIA

Channels high–voltage current from
the ignition coil to the individual
spark plugs.

FUSE

A thin metal strip which burns through
when too much current flows through it,
thereby stopping current flow and
protecting a circuit from damage.

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.

FUEL

M

LIGHT

Current flow through a filament
causes the filament to heat up and
emit light.

LED (LIGHT EMITTING DIODE)

Upon current flow, these diodes emit
light without producing the heat of a
comparable light.

METER, ANALOG

Current flow activates a magnetic
coil which causes a needle to move,
thereby providing a relative display
against a background calibration.

METER, DIGITAL

Current flow activates one or many
LED’s, LCD’s, or fluorescent
displays, which provide a relative or
digital display.

MOTOR

A power unit which converts
electrical energy into mechanical
energy, especially rotary motion.

RESISTOR

RESISTOR, TAPPED

RESISTOR, VARIABLE or RHEOSTAT

Basically, an electrically operated
switch which may be normally
closed (1) or open (2).
Current flow through a small coil
creates a magnetic field which either
opens or closes an attached switch.

A relay which passes current
through one set of contacts or the
other.

An electrical component with a fixed
resistance, placed in a circuit to
reduce voltage to a specific value.

A resistor which supplies two or
more different non adjustable
resistance values.

A controllable resistor with a variable
rate of resistance.
Also called a potentiometer or
rheostat.

SPEAKER

An electromechanical device which
creates sound waves from current
flow.

SWITCH, MANUAL

1. NORMALLY
OPEN

2. NORMALLY
CLOSED

SWITCH, DOUBLE THROW

A switch which continuously passes
current through one set of contacts
or the other.

SWITCH, IGNITION

A key operated switch with several
positions which allows various
circuits, particularly the primary
ignition circuit, to become
operational.

circuits, thereby
stopping (1) or
allowing (2) current
flow.

(Reed Switch Type)

SENSOR (Thermistor)

A resistor which varies its resistance
with temperature.

SENSOR, SPEED

Uses magnetic impulses to open
and close a switch to create a signal
for activation of other components.

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.

SWITCH, WIPER PARK

Automatically returns wipers to the
stop position when the wiper switch
is turned off.

TRANSISTOR

A solidstate device typically used as
an electronic relay; stops or passes
current depending on the voltage
applied at ”base”.

WIRES

(1) NOT
CONNECTED

(2) SPLICED

Wires are always drawn as
straight lines on wiring
diagrams.
Crossed wires (1) without a

not joined;
crossed wires (2) with a
black dot or octagonal ( )
mark at the junction are
spliced (joined)
connections.

Engine Control

System Outline

The engine control system utilizes a microcomputer and maintains overall control of the engine, etc. An outline of engine
control is given here.

1. Input Signals

(1) Engine coolant temp. signal system

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. Thus the engine coolant temp. is input as a control signal to TERMINAL
THW of the engine control module.

(2) Intake air temp. signal system

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) Power steering oil pressure signal system

Power steering oil pressure is detected by the power steering oil pressure SW and is input as a control signal to
TERMINAL PSW of the engine control module.

(4) RPM signal system

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 G2+ of the engine control module, and engine RPM is input
into TERMINAL NE+.

(5) Throttle signal system

The throttle position sensor detects the throttle valve opening angle, which is input as a control signal to TERMINALS
VTA1 and VTA2 of the engine control module.

(6) Vehicle speed signal system

The vehicle speed is detected by the ABS speed sensor and the signal is input to TERMINAL SPD of the engine control
module via the comb. meter and the skid control ECU with actuator. (w/ ABS)
The vehicle speed is detected by the vehicle speed sensor installed in the transaxle and the signal is input to
TERMINAL SPD of the engine control module via the comb. meter. (w/o ABS)

(7) NSW signal system (A/T)

The Park/Neutral position SW detects whether the shift position is in neutral or not, and inputs a control signal to
TERMINAL NSW of the engine control module.

(8) A/C SW signal system

The operating voltage of the A/C SW is detected and is input as a control signal to TERMINAL A/CS of the engine
control module.

(9) Battery signal system

Voltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned to on,
voltage for engine control module operation is applied via the EFI relay to TERMINAL +B of the engine control module.

(10)Intake air volume signal system

Intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of the engine
control module.

(11) STA signal system

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 control module.

(12)Oxygen sensor signal system

The oxygen density in the exhaust gases is detected and is input as a control signal into TERMINAL OX1B of the
engine control module. To maintain stable detection performance by the oxygen sensor, a heater is used for warming
the sensor. The heater is also controlled by the engine control module (HT1B).

(13)Engine knock signal system

Engine knocking is detected by the knock sensor (Bank 1) and input as a control signal to TERMINAL KNK1 of the
engine control module.

(14)Electrical load signal system

When systems which cause a high electrical load such as the rear window defogger, taillight are turned on, a signal is
input to TERMINALS ELS1 and ELS2 as a control signal.

(15)Air fuel ratio signal circuit

The air fuel ratio is detected and input as a control signal into TERMINAL A1A+ of the engine control module.

2. Control System

S1

:

∗ SFI system

The SFI system monitors the engine conditions through the signals, which are input from each sensor to the engine
control module. Based on this data and the program memorized in the engine control module, the most appropriate fuel
injection timing is decided and current is output to TERMINALS #10, #20, #30 and #40 of the engine control module,
operating the injectors (to inject fuel). This is the system which finely controls the fuel injection in response to the driving
conditions, through the engine control module.

∗ ESA system

The ESA system monitors the engine conditions using the signals, which are input to the engine control module from each
sensor. Based on this data and the program memorized in the engine control module, the most appropriate ignition timing
is decided and current is output to TERMINALS IGT1, IGT2, IGT3 and IGT4 of the engine control module. This output
controls the ignition coil and igniter No. 1 , No. 2 , No. 3 and No. 4 to produce the most appropriate ignition timing for the
driving conditions.

∗ Knock control system

Knock control system controls the gate based on the engine rotation speed and detects knocking by the peak value of the
knock sensor (Bank 1) output during the gate open period, and then controls it to the most suitable ignition timing in
proportion to the driving condition.

∗ Evapoparge control system

This system leads the vapor stuck to the canister to the serge tank in order not to agitate the air fuel by adjusting the fuel
injection volume.
The signal at this time will be output from TERMINAL PRG of the engine control module to VSV (Purge).

3. Diagnosis System

With the diagnosis system, when there is a malfunctioning in the engine control module signal system,the malfunction
system is recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the malfunction
indicator lamp.

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 the data (Standard values)
recorded in the engine control module memory or else stops the engine.

System Outline

The current is always flowing from the HEAD MAIN fuse to HEAD relay (Coil side) to TERMINAL 6 of the daytime running
light relay and from ECU–B fuse to TERMINAL 3 of the daytime running light relay. The current is always flowing from the
TAIL fuse to TAIL relay (Coil side) to TERMINAL 14 of the daytime running light relay.
When the ignition SW is turned on, the current flowing through the GAUGE fuse flows to TERMINAL 12 of the daytime
running light relay.

1. Daytime Running Light Operation

When the engine is started, voltage generated at TERMINAL L of the generator is applied to TERMINAL 8 of the daytime
running light relay. If the parking brake lever is pulled up (Parking brake SW on) at this time, the relay is not activated so the
daytime running light system does not operate. If the parking brake lever is then released (Parking brake SW off), a signal is
input to TERMINAL 11 of the relay.
This activates the daytime running light relay and the HEAD relay is turned to on, so the current flows from the HEAD MAIN
fuse to the HEAD relay (Point side) to HEAD LH LWR, HEAD RH LWR fuses to TERMINAL 2 of the headlights to TERMINAL
1 to TERMINAL 1 of the daytime running light relay to TERMINAL 2 to GROUND, causing the headlights to light up
(Headlights light up dimmer than normal brightness.). Once the daytime running light system operates and the headlights
light up, the headlights remain on even if the parking brake lever is pulled up (Parking brake SW on).
If the engine stalls and the ignition SW remains on, the headlights remain light up even through current is no longer output
from TERMINAL L of the generator. If the ignition SW is then turned off, the headlights go off.
If the engine is started with the parking brake lever released (Parking brake SW off), the daytime running light system
operates and headlights light up when the engine starts.

2. Headlight Operation

When the light control SW is switched to Head position and the dimmer SW is set to Low position, causing the daytime
running light relay and the HEAD relay to turn on, so the current flows from the HEAD MAIN fuse to HEAD relay (Coil side) to
TERMINAL 6 of the daytime running light relay to TERMINAL 7 to TERMINAL 12 of the light control SW to TERMINAL 11 to
GROUND. The current to HEAD relay (Point side) then flows to HEAD LH LWR, HEAD RH LWR fuses to TERMINAL 2 of the
headlights (Low) to TERMINAL 1 to TERMINAL 1 of the daytime running light relay to TERMINAL 2 to GROUND, causing
the headlights to light up at normal intensity.
When the light control SW is switched to Head position and the dimmer SW is set to High position, the signal from the
dimmer SW is input to the daytime running light relay. This activates the daytime running light relay and the HEAD relay is
turned on, so the current flows from the HEAD MAIN fuse to HEAD relay (Point side) to TERMINAL 1 of the DIMMER relay to
TERMINAL 2 to TERMINAL 13 of the daytime running light relay, activating the DIMMER relay. This causes current to flow
from TERMINAL 3 of the DIMMER relay to TERMINAL 5 to HEAD LH UPR, HEAD RH UPR fuses to TERMINAL 2 of the
headlights (High) to TERMINAL 1 to GROUND, causing the headlights to light up at high beam and the high beam indicator
light to light up.
When the dimmer SW is switched to Flash position, the signal from the dimmer SW is input to the daytime running light relay.
This activates the daytime running light relay and the HEAD relay is turned on, so the current flows from the HEAD MAIN
fuse to HEAD relay (Point side) to TERMINAL 1 of the DIMMER relay to TERMINAL 2 to TERMINAL 13 of the daytime
running light relay, activating the DIMMER relay, and also flows from the HEAD LH UPR, HEAD RH UPR fuses to
TERMINAL 2 of the headlights to TERMINAL 1 to GROUND, causing the headlights to light up at high beam and the high
beam indicator light to light up.

3. Automatic Light Control Operation (USA)

When the daytime running light is operating and the Automatic control sensor detects a decrease in the ambient light, the
automatic light control operation starts. At the same time, daytime running light relay is activated, so current flows from the
TAIL fuse to the TAIL relay (Coil side) to TERMINAL 14 of the daytime running light relay, and the HEAD MAIN fuse to the
HEAD relay (Coil side) to TERMINAL 6 of the daytime running light relay, activating both the TAIL relay and the HEAD relay,
so that the taillights and headlights light up.
When the automatic light control sensor detects an increase in the ambient light, the ignition SW is turned to off, the light
control SW is turned to Head position, and the automatic light control operation stops.

System Outline

With the ignition SW turned on, the current flows to TERMINAL 8 of the front wiper and washer SW, TERMINAL 2 of the front
wiper motor through the WIPER fuse, and the current flows to TERMINAL 2 of the washer motor through the WASHER fuse.

1. Low Speed Position

With the front wiper SW turned to LO position, the current flows from TERMINAL 8 of the front wiper and washer SW to
TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes to the front 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 8 of the front wiper and washer SW to
TERMINAL 9 to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes to the wiper motor to run at
high speed.

3. INT Position

With the front wiper SW turned to INT position, the wiper relay operates and the current which is connected by relay function
flows from TERMINAL 8 of the front wiper and washer SW to TERMINAL 5 to GROUND. This flow of current operates the
intermittent circuit and the current flows from TERMINAL 8 of the front wiper and washer SW to TERMINAL 7 to TERMINAL
1 of the front wiper motor to TERMINAL 5 to GROUND and the functions.
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 (w/ intermittent volume SW) to change the charging time of the
condenser.

4. MIST Position

With the front wiper SW turned to MIST position, the current flows from TERMINAL 8 of the front wiper and washer SW to
TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes to the front wiper motor to
run at low speed.

5. Washer Continuous Operation

With the front washer SW turned to on, the current flows from TERMINAL 2 of the front washer motor to TERMINAL 1 to
TERMINAL 4 of the front wiper and washer SW to TERMINAL 5 to GROUND and causes to the washer motor to run, and
the window washer jet operates. This causes the current to flow to washer continuous operation circuit in TERMINAL 8 of
the front wiper and washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and
the washer operates continuously.
