DTC
B0103/12
SHORT IN D SQUIB CIRCUIT (TO B+)
CIRCUIT DESCRIPTION
The D squib circuit consists of the airbag sensor assy center, spiral cable sub-assy and horn button assy.
It causes the SRS to deploy when the SRS deployment conditions are satisfied.
DTC B0103/12 is recorded when a B+ short is detected in the D squib circuit.
DTC No.
