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 ON, the current from the IGN fuse flows to TERMINAL (B) 5 of the airbag sensor
assembly.
If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the IGN fuse flows to
TERMINALS (B) 14, (B) 16, (B) 10, (B) 8, (A) 8 (w/ curtain shield airbag), or (A) 2 (w/o curtain shield airbag) and (C) 9 (w/
curtain shield airbag), or (C) 5 (w/o curtain shield airbag) of the airbag sensor assembly to the airbag squibs and the
pretensioners to TERMINALS (B) 13, (B) 17, (B) 11, (B) 7, (A) 7 (w/ curtain shield airbag), or (A) 1 (w/o curtain shield airbag)
and (C) 10 (w/ curtain shield airbag), or (C) 6 (w/o curtain shield airbag) of the airbag sensor assembly to TERMINAL (B) 27,
(B) 28 or BODY GROUND to GROUND, so that current flows to the airbag squibs and the pretensioners and causes them to
operate.
When the side impact also exceeds a set level, the current from the IGN fuse flows to TERMINALS (A) 12, (C) 5, (A) 9 and
(C) 8 of the airbag sensor assembly to the side airbag squibs and the curtain shield airbag squibs TERMINALS (A) 11, (C) 6,
(A) 10 and (C) 7 of the airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, causing side
airbag squibs and curtain shield airbag squibs to operate.
The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.
The airbag stored inside the passenger's instrument panel is instantaneously expanded to soften the shock to the front
passenger.
Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger.
The curtain shield airbag can ease an impact on the head of the front and rear passengers and reduce risks of injury.
In a head-on crash, the driver moves forward and may strike his/her lower limbs against the instrument panel, the key
cylinder, etc.
The pretensioners make sure of the seat belt restrainability.

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.

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.
