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 ON, the current from the ignition SW flows to TERMINAL (C) 5 of the airbag sensor
assembly.
If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the ignition SW flows to
TERMINALS (C) 14, (C) 16, (C) 10, (C) 8, (A) 8 (w/ side airbag) or (B) 2 (w/o side airbag) and (D) 9 (w/ side airbag) or (E) 5
(w/o side airbag) of the airbag sensor assembly to the airbag squibs and the pretensioners to TERMINALS (C) 13, (C) 17,
(C) 11, (C) 7, (A) 7 (w/ side airbag) or (B) 1 (w/o side airbag) and (D) 10 (w/ side airbag) or (E) 6 (w/o side airbag) of the
airbag sensor assembly to TERMINAL (C) 27, (C) 28 or BODY GROUND to GROUND, so that current flows to the airbag
squibs and the pretensioners and causes them to operate.
When the side impact also exceeds a set level, the current from the ignition SW flows to TERMINALS (A) 12, (D) 5, (A) 9 and
(D) 8 of the airbag sensor assembly to the side airbag squibs and the curtain shield airbag squibs TERMINALS (A) 11, (D) 6,
(A) 10 and (D) 7 of the airbag sensor assembly to TERMINAL (C) 27, (C) 28 or BODY GROUND to GROUND, causing side
airbag squibs and curtain shield airbag squibs to operate.
The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.
The airbag stored inside the passenger’s instrument panel is instantaneously expanded to soften the shock to the front
passenger.
Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger.
The curtain shield airbag can ease an impact on the head of the front and rear passengers and reduce risks of injury.
The pretensioners make sure of the seat belt restrainability.
