System Outline
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/RADIO fuse flows to TERMINAL 14 of the airbag sensor assembly. Only when the Ignition SW is ON the current from the IGN fuse to TERMINAL 13.
If an accident occurs while driving, when the frontal impact exceeds a set level, current from the CIG/RADIO or IGN fuse flows to TERMINALS 3 and 2 of the Airbag Sensor Assembly --> TERMINAL 1 of the airbag squib -->TERMINAL 2 --> TERMINALS 4 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 passenger's instrument panel is instantaneously expanded to soften the shock to the passenger.
