Restraints and Safety Systems: Description and Operation

The SRS is a driver and passenger protection device which has a supplemental role to the seat belts.

When the ignition SW is turned to ACC or ON current from the CIG fuse flows to TERMINAL 16 of the airbag sensor assembly. Only when the ignition SW is ON does the current from the IGN fuse to TERMINAL 15.

If an accident occurs while driving, when the frontal impact exceeds a set level, current from the CIG or IGN fuse flows to TERMINALS 7 and 3 of the airbag sensor assembly to TERMINAL 1 of the airbag squib to TERMINAL 2 to TERMINALS 6 and 2 of the airbag sensor assembly to TERMINAL 10, TERMINAL 9 or BODY GROUND to GROUND, so that current flows to the airbag squibs and causes it 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 passenger.
