SRS
The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts.
When the ignition SW is on does, current from the SRS
−
IG fuse flows to TERMINAL (A) 6.
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
SRS
−
IG fuse flows to TERMINALS (A) 14, (A) 10 of the center airbag sensor assembly to TERMINAL 1 of the airbag squib
to TERMINAL 2 to TERMINALS (A) 13, (A) 11 of the center airbag sensor assembly to TERMINAL (A) 27, TERMINAL (A) 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 SRS
−
IG fuse flows to TERMINALS (A) 14, (A) 10 of the center airbag sensor
assembly to TERMINAL 1 of the airbag squib to TERMINAL 2 to TERMINALS (A) 13, (A) 11 of the center airbag sensor
assembly to TERMINAL (A) 9 or (A) 15 to TERMINAL 2 of the front airbag sensor to TERMINAL 1 to TERMINAL (A) 20 or
(A) 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.
