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 OPERATION on page RS±2.
DTC B0106/54 is recorded when an open is detected in the P squib circuit.

See page DI±657.
INSPECTION PROCEDURE
1 Prepare for inspection. (See step 1 on page DI±787)
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

3 Check airbag sensor assembly.
PREPARATION:
(a) Connect the connector to the airbag sensor assembly.
(b) Using a service wire, connect P+ and P± of the connector
(on the front passenger airbag assembly side) between
the front passenger airbag assembly and the airbag sen-
sor assembly.
(c) Connect negative (±) terminal cable to the battery, and
wait at least for 2 seconds.
CHECK:
(a) Turn ignition switch to ACC or ON and wait at least for 20
seconds.
(b) Clear DTC stored in memory.
(See page DI±626)
(c) Turn ignition switch to LOCK, and wait at least for 20 se-
conds.
(d) Turn ignition switch to ACC or ON, and wait at least for 20
seconds.
(e) Check DTC.
(See page DI±626)
OK:
DTC B0106/54 is not output.
HINT:
Codes other than code B0106/54 may be output at this time, but
they are not relevant to this check.
