DTC B0106/54 Open in P Squib Circuit
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 Pub. No. RM654U on page RS±2.
DTC B0106/54 is recorded when an open is detected in the P squib circuit.

INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI±305).
2 Check P squib circuit.
CHECK:
For the connector (on the front passenger airbag assembly
side) between the front passenger airbag assembly and the air-
bag sensor assembly, measure the resistance between P+ and
P±.
OK:
Resistance: Below 1 W
NG Repair or replace harness or connector be-
tween front passenger airbag assembly and air-
bag sensor assembly.
OK
