Circuit Operation

The SRS is a driver and front passenger protection device which has a supplemental role to the seal belts.

When the ignition SW is turned ON the current from the SRS fuse flows to the center airbag sensor assembly TERMINAL 6.

Only when the ignition SW is ON does the current from the IGN fuse flow to center airbag sensor assembly TERMINAL 5.

In case an accident occurs while driving, when the frontal impact exceeds a predetermined level, the current from the SRS or IGN fuse flows to center airbag sensor assembly TERMINALS 14, 10, 16, 8 to airbag squibs and pretensioners to center airbag sensor assembly TERMINALS 13, 11, 17, 7 to TERMINALS 27, 28 or BODY GROUND to GROUND.

The current flows to the airbag squibs and pretensioners and operates the airbag.

The airbag stored in the steering wheel pad is instantaneously expanded to soften the shock to the driver.

The airbag stored in the front passenger's instrument panel is instantaneously expanded to soften the shock to the front passenger.

The pretensioners ensure the seat belt restrainability.
