System Outline

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

If an accident occurs while driving, deceleration caused by a frontal impact is detected by each sensor and switch, and the frontal impact exceeds a set level (when the Safing Sensor Built into the Center Airbag sensor Assembly is ON and the center Airbag Sensor is ON), the current from the CIG or IGN fuse flows through the airbag sensor assembly to TERMINAL 7 and 3of the center Airbag sensor Assembly TERMINAL 1 of the airbag squib --> TERMINAL 2 --> TERMINALS 6, 2 of the center airbag sensor assembly to floor sensor built into the airbag sensor assembly --> TERMINAL 9, TERMINAL 10 or BODY GROUND --> GROUND.

When the safing sensor built into the center Airbag sensor Assembly is ON, and the floor sensor built into the center Airbag sensor Assembly is ON, one of the above-mentioned circuits is activated so that current flows to the Airbag Squibs and causes them to operate.

The Airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the Driver.
Simultaneously, the Airbag stored inside the steering wheel pad passenger's instrument panel is instantaneously expanded to soften the shock to the passenger.
