System Outline

The SRS is a protection device for a driver and front passenger which has a supplemental role to the seat belts. When the power SW is pushed to IG ON position, the current from the IGN fuse flows to TERMINAL (B) 21 of the airbag sensor assembly.

If an accident occurs while driving, when the frontal impact exceeds set level, the current from the IGN fuse flows to TERMINALS (B) 5, (B) 8, (B) 4, (B) 1, (A) 5 and (C) 4 of the airbag sensor assembly to the airbag squibs and the pretensioners to TERMINALS (B) 6, (B) 7, (B) 3, (B) 2, (A) 6 and (C) 3 of the airbag sensor assembly to TERMINAL (B) 25, (B) 26 or BODY GROUND to GROUND. The flowing current activates the airbag squibs and the pretensioners.

When the side impact exceeds set level, the current from the SRS fuse flows to TERMINALS (A) 1, (C) 8, (A) 4 and (C) 5 of the airbag sensor assembly to the side airbag squibs and the curtain shield airbag squibs TERMINALS (A) 2, (C) 7, (A) 3 and (C) 6 of the airbag sensor assembly to TERMINAL (B) 25, (B) 26 or BODY GROUND to GROUND, which activates side airbag squibs and curtain shield airbag squibs.

The airbag stored inside the steering wheel pad is instantaneously expanded to reduce the shock to the driver.
The airbag stored inside the passenger's instrument panel expands instantaneously to reduce shock to the front passenger.

Side airbags expand instantaneously to reduce side shock to the driver and front passenger.
The curtain shield airbag can reduce impact on the head of the front and rear passengers and reduce risk of injury.
The pretensioner helps to maximize the seat belt restraint.
