With the ignition SW turned on, the current flows to TERMINAL 17 of the front wiper and washer SW, TERMINAL 2 of the
front wiper motor through the WIPER fuse, the current flows to TERMINAL 1 of the washer motor through WASHER fuse.
1. Low Speed Position
With the wiper SW turned to LOW position, the current flows through TERMINAL 17 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 the wiper motor to run at low
speed.
2. High Speed Position
With the wiper SW turned to HIGH position, the current flows through TERMINAL 17 of the front wiper and washer SW to
TERMINAL 8 to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes the 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
through TERMINAL 17 of the front wiper and washer SW to TERMINAL 2 to GROUND. This flow of current operates the
intermittent circuit and the current flows through TERMINAL 17 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 wiper functions.
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 charge the charging time of condenser.
4. Washer Continuous Operation
With the washer SW pulled to on, the current flows through TERMINAL 1 of the washer motor to TERMINAL 2 to TERMINAL
11 of the front wiper and washer SW to TERMINAL 2 to GROUND and causes the washer motor to run and the window
washer to jet. This causes the current to flow to washer continuous operation circuit in TERMINAL 17 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 wiper functions.

1. Seat Belt Warning System
When the ignition SW is turned to the ON position, the signal is input to the body ECU. At this time, to judge whether or not
the driver fastens the seat belt, the signal from the buckle SW LH is input to TERMINAL (A) 10 of the body ECU via multiplex
commnunication system (Bean bus). If the driver does not fasten the seat belt, the seat belt warning light in the combination
meter flashes and the alarm buzzer goes on, in response to the communication control of the body ECU etc.
Additionally, the sensor (Inside of buckle SW (Front passenger's side) ) installed on the front passenger seat detects the
passenger and determines whether or not the passenger fastens the seat belt.
If the passenger does not fasten the seat belt, the front passenger seat belt warning light is flashed.
2. Key Reminder 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 (B) 2 of the
body ECU and the signal from the door courtesy SW LH is input to TERMINAL (C) 11 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.

When the ignition SW is turned to ACC position, the current from the RAD NO.2 fuse flows to TERMINAL 1 of the shift lock
ECU. When the ignition SW is turned to ON position, the current from the ECU-IG fuse flows to TERMINAL 5 of the ECU.
1. Shift Lock Mechanism
With the ignition SW on, when a signal that the brake pedal is depressed (Stop light SW on) and a signal that the shift lever
is put in P position (Continuity between P1 and P of the shift lock control SW) is input to the ECU, the ECU activates and the
current flows from TERMINAL 5 of the ECU to TERMINAL SLS+ of the shift lock solenoid to solenoid to TERMINAL SLS- to
TERMINAL 3 of the ECU to GROUND. This causes the shift lock solenoid to turn on (Lock plate disengages) and the shift
lever can be shifted into other position than the P position
2. Key Inter Lock Mechanism
With the ignition SW ON or ACC position, when the shift lever is put in P position (No continuity between P2 and P of shift
lock control SW), the current flowing from TERMINAL 4 of the ECU to the key interlock solenoid is cut off. This causes the
key interlock solenoid to turn off (Lock plate disengages from LOCK position) and the ignition key can be turned from ACC to
LOCK position.
