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 & RAD fuse flows to TERMINAL 6 of the center airbag sensor assembly. Only when the ignition SW is ON does, current from the IGN fuse flows to TERMINAL 5.
If an accident occurs while driving, deceleration caused by a frontal impact is detected by each of the sensor and the switch, in the center airbag sensor assembly and when 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 front airbag sensor are OFF), current from the CIG & RAD or the IGN fuse flows to TERMINALS 14,10 of the center airbag sensor assembly to TERMINAL 11 of the airbag squib to TERMINAL 10 to TERMINALS 13, 11 of the center airbag sensor assembly to TERMINAL 27, TERMINAL 28 or BODY GROUND to GROUND.
When the safing sensor built into the center airbag sensor assembly is ON and the front airbag sensor LH or RH is ON, the center airbag sensor is OFF and current from the CIG & RAD or the IGN fuse flows to TERMINALS 14,10 of the center airbag sensor assembly to TERMINAL 11 of the airbag squib to TERMINAL 10 to TERMINALS 13, 11 of the center airbag sensor assembly to TERMINAL 9 or 15 to TERMINAL 11 of the front airbag sensor to TERMINAL 10 to TERMINAL 20 or 26 of the center airbag sensor assembly to TERMINAL 27, TERMINAL 28 or BODY GROUND to GROUND, when the safing sensor built into the center airbag sensor assembly is ON, and the front airbag sensor LH or RH is ON and the center airbag sensor is ON, one of the above-mentioned circuits is activated so that current flows to the airbag squibs, causing it 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 passenger's instrument panel is instantaneously expanded to soften the shock to the passenger.
