CIRCUIT DESCRIPTION
The P squib circuit consists of the airbag sensor assembly and 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-2 .
DTC B0108/52 is recorded when a B+ short is detected in the P squib circuit.

 From the results of the above inspection, the malfunctioning part can now be considered normal.
 To make sure of this, use the simulation method to check. If the malfunctioning part can not be
 detected by the simulation method, replace all SRS components including the wire harness.
