DTC B0108/52 Short in P Squib Circuit (to B+)
CIRCUIT DESCRIPTION
The P squib circuit consists of the airbag sensor assembly and the front passenger airbag assembly.
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 B0108/52 is recorded when a B+ short is detected in the P squib circuit.
