DTC B0108/52 Short in P Squib Circuit (to B+)
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.

INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI±629).
2 Check P squib circuit.
CHECK:
(a) Turn the ignition switch to ON.
(b) For the connector (on the front passenger airbag assem-
bly side) between the front passenger airbag assembly
and the airbag sensor assembly, measure the voltage be-
tween the P+ and body ground.
OK:
Voltage: 0 V
NG Repair or replace harness or connector be-
tween front passenger airbag assembly and air-
bag sensor assembly.
