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, the current from the ACC fuse flows to TERMINAL 10 of the Airbag sensor assembly. Only when the Ignition SW is ON does, the current from the IGN fuse flows to TERMINAL 9 of the assembly. If an accident occurs while driving, deceleration caused by a frontal impact is detected by the sensor in the Airbag sensor assembly, and when the frontal impact exceeds a set level (When The Safing Sensor Built Into The Airbag Sensor Assembly is ON, The Floor Sensor Built Into The Airbag Sensor Assembly Is ON And The Airbag Sensor Assembly IS ON), the current from the ACC or the IGN fuse flows through the Airbag sensor assembly to TERMINAL 4and 2 of the Airbag sensor assembly to TERMINAL 1 of the Airbag Squib --> TERMINAL 2 --> TERMINAL 3 and 1 of the Airbag sensor assembly --> the floor sensor built into the Airbag sensor assembly --> TERMINAL 5, TERMINAL 6 or Body Ground --> Ground. When the safing sensor built into the Airbag sensor assembly is ON, and floor sensor built into the Airbag sensor assembly is ON, one of the above-mentioned circuit is activated so that the 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 a driver.
Simultaneously, the Airbag stored inside the passengers instrument panel is instantaneously expanded to soften the shock to a passenger.
