DTC 12 Short in Squib Circuit (to B+)

CIRCUIT DESCRIPTION

The squib circuit consists of the center airbag sensor assembly, spiral cable, steering wheel pad and front pas-
senger airbag assembly. It causes the SRS to deploy when the SRS deployment conditions are satisfied.
The front airbag sensor detects the deceleration force in a frontal collision and is located in the front fender on
the left and right sides.
For details of the function of each component, see FUNCTION OF COMPONENTS on page RS–4.

circuit.
