DTC B0102/11 Short in D Squib Circuit (to Ground)
CIRCUIT DESCRIPTION
The D squib circuit consists of the airbag sensor assembly, the spiral cable and the steering wheel pad.
It causes the SRS to deploy when the SRS deployment conditions are satisfied.
For details of the function of each component, see OPERATION on page RS-3.
DTC B0102/11 is recorded when a ground short is detected in the D squib circuit.
