DTCB0102/11SHORT IN D SQUIB CIRCUIT (TO GROUND)
CIRCUIT DESCRIPTION
The D squib circuit consists of the airbag sensor assy center, the spiral cable sub±assy and the horn button
assy.
This circuit actuates the SRS to deploy when the SRS deployment conditions a\
re fulfilled.
DTC B0102/11 is recorded when a short to ground is detected in the D squib circuit.\
