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 turned to ACC or ON, the current from the SRS fuse flows to the center airbag sensor assembly TERMINAL
(B) 6. Only when the ignition SW is ON does the current from the IGN fuse flow to center airbag sensor assembly
TERMINAL (B) 5.
In case an accident occurs while driving, when the frontal impact exceeds a predetermined level, the current from the center
airbag sensor assembly TERMINAL (B) 14 to airbag squibs TERMINAL 1 to TERMINAL 2 to center airbag sensor assembly
TERMINAL (B) 13 to TERMINAL (B) 27, (B) 28 to GROUND or BODY GROUND. The current flows to the airbag squibs,
and the airbag stored in the steering wheel is expanded instantaneously to reduce the impact to the driver.
As for the passenger side seat, if the passenger airbag manual ON/OFF SW is on, the current flows from the center airbag
sensor assembly TERMINAL (B) 10 to passenger airbag manual SW ON/OFF SW TERMINAL (B) 1 to TERMINAL (B) 2 to
airbag squibs TERMINAL 2 to TERMINAL 1 to passenger airbag manual SW ON/OFF SW TERMINAL (B) 3 to TERMINAL
(B) 4 to center airbag sensor assembly TERMINAL (B) 11 to TERMINAL (B) 27, (B) 28 to GROUND or BODY GROUND.
