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 10 of the center Airbag sensor Assembly. Only when the Ignition SW is ON does the current from the IGN fuse to TERMINAL 9.

If an accident occurs while driving, when the frontal impact exceeds a set level, current from the CIG or IGN fuse flows to TERMINAL 4 and 2 of the center Airbag sensor Assembly --> TERMINAL 1 of the Airbag squib --> TERMINAL 2 --> TERMINAL 3 and 1 of the Airbag sensor Assembly --> TERMINAL 5, TERMINAL 6 or BODY GROUND --> 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 front passenger Airbag Assembly is instantaneously expanded to soften the shock to the passenger.
