B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.

This system utilizes an engine control module and maintains overall control of the engine, transmission 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. thus the engine coolant temp. is input in the form of a control signal into
TERMINAL THW of the engine control module.
(2) Intake air temp. signal circuit
The intake air temp. sensor detects the intake air temp. , which is input as a control signal into TERMINAL THA of the
engine control module.
(3) Oxygen sensor signal circuit
The oxygen density in the exhaust gases is detected and input as a control signal into TERMINAL OX2 of the engine
control module.
(4) 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 control module, and engine RPM is input
into TERMINAL NE.
(5) Throttle signal circuit
The throttle position sensor detects the throttle valve opening angle, which is input as a control signal into TERMINAL
VTA of the engine control module.
(6) Vehicle speed signal 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) Park/Neutral position SW signal circuit
The Park/Neutral position SW detects whether the shift position are in neutral, parking or not, and inputs a control signal
into TERMINAL STA of the engine control module.
(8) A/C SW signal circuit
The A/C amplifier is built in the engine control module. The signal from the A/C SW is input into TERMINAL A/CS of the
engine control module.
(9) Battery signal circuit
Voltage is constantly applied to TERMINAL BATT of the engine control module. When the ignition SW is turned on, the
voltage for engine control module start±up power supply is applied to TERMINAL +B of engine control module via EFI
relay.
(10) Intake air volume signal circuit
Intake air volume is detected by the manifold absolute pressure sensor (for manifold pressure) and is input as a control
signal into TERMINAL PIM of the engine control module.
(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 NSW of the engine control module as a control signal.
(12) Electrical load signal circuit
The signal when systems such as the rear window defogger, headlights, etc. Which cause a high electrical burden are
on is input to TERMINAL ELS as a control signal.
(13) Air fuel ratio signal circuit
The air fuel ratio is detected and input as a control signal into TERMINAL AF+ of the engine control module.

With the ignition SW turned on, the current flows to TERMINAL 17 of the wiper and washer SW, TERMINAL 2 of the washer
motor and TERMINAL 2 of the front wiper motor through the WIPER fuse.
1. LOW SPEED POSITION
With the wiper and washer SW turned to LO position, the current flows from TERMINAL 17 of the wiper and washer SW to
TERMINAL 7 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to GROUND and causes the front wiper motor to run
at low speed.
2. HIGH SPEED POSITION
With the wiper and washer SW turned to HI position, the current flows from TERMINAL 17 of the wiper and washer SW to
TERMINAL 8 to TERMINAL 3 of the front wiper motor to TERMINAL 4 to GROUND and causes the front wiper motor to run
at high speed.
3. INT POSITION
With the wiper and washer SW turned to INT position, the wiper relay operates and current flows from TERMINAL 17 of the
wiper and washer SW to TERMINAL 2 to GROUND. This activates the intermittent circuit and the current flows from
TERMINAL 17 of the wiper and washer SW to TERMINAL 7 to TERMINAL 5 of the front wiper motor to TERMINAL 4 to
GROUND and the wiper operates. Intermittent operation is controlled by a condenser charge and discharge function in the
relay.
4. WASHER CONTINUOUS OPERATION
With the wiper and washer SW pulled to WASHER position (Washer SW ON position), the current flows from the WIPER
fuse to TERMINAL 2 of the washer motor to TERMINAL 1 to TERMINAL 11 of the wiper and washer SW to TERMINAL 2 to
GROUND and causes the washer motor to run and the window washer to spray. Simultaneously, current flows from the
WIPER fuse to TERMINAL 17 of the wiper and washer SW to TERMINAL 7 to TERMINAL 5 of the front wiper motor to
TERMINAL 4 to GROUND, causing the wiper to function.
