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 Pub. No. RM654U 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±305).
2 Check P squib circuit.
CHECK:
(a) Turn 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.
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 step 5 on page
DI±223).
(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±223).
OK:
DTC B0108/52 is not output.
HINT:
Codes other than code B0108/52 may be output at this time, but
they are not relevant to this check.
NG Replace airbag sensor assembly.

PREPARATION:
(a) Turn ignition switch to LOCK.
(b) Disconnect negative (±) terminal cable from the battery,
and wait at least for 90 seconds.
(c) Connect the front passenger airbag assembly connector.
(d) 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±223).
(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±223).
OK:
DTC B0108/52 is not output.
HINT:
Codes other than code B0108/52 may be output at this time, but
they are not relevant to this check.
NG Replace front passenger airbag assembly.
OK
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.
