4 Check P/T squib (LH).
PREPARATION:
(a) Turn the ignition switch to LOCK.
(b) Disconnect negative (-) terminal cable from the battery,
and wait at least for 90 seconds.
(c) Connect the seat belt pretensioner (LH) connector.
(d) Connect negative (-) terminal cable to the battery, and
wait at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(b) Clear the DTC stored in memory
(See step 5 on page DI-349).
(c) Turn the ignition switch to LOCK, and wait at least for 20
seconds.
(d) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(e) Check the DTC (See page DI-349).
OK:
DTC B0137/71 is not output.

DTC B0138/72 Short in P/T Squib (LH) Circuit (to B+)
CIRCUIT DESCRIPTION
The P/T squib (LH) circuit consists of the airbag sensor assembly and seat belt pretensioner (LH).
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-3.
DTC B0138/72 is recorded when a B+ short is detected in the P/T squib (LH) circuit.

INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI-475).
2 Check P/T squib (LH) circuit.
CHECK:
(a) Turn the ignition switch to ON.
(b) For the connector (on the seat belt pretensioner side) be-
tween the seat belt pretensioner (LH) and the airbag sen-
sor assembly, measure the voltage between PL+ and
body ground.
OK:
Voltage: 0 V
NG Repair or replace harness or connector be-
tween seat belt pretensioner (LH) and airbag
sensor assembly.
OK

2 Check source voltage.
PREPARATION:
Connect negative (-) terminal cable to the battery.
CHECK:
(a) Turn ignition switch ON.
(b) Measure the voltage between body ground and each of
IG2 and ACC on the sensor and operate electric system
(defogger, wiper, headlight, heater blower, etc.).
OK:
Voltage: 10 - 14 V
NG Check harness between battery and airbag sen-
sor assembly, and check battery and charging
system.
OK

PREPARATION:
(a) Turn the ignition switch to LOCK.
(b) Connect the steering wheel pad connector.
(c) Connect the front passenger airbag assembly connector.
(d) Connect the side airbag assembly connectors.
(e) Connect the seat belt pretensioner connectors.
(f) Connect the airbag sensor assembly connectors.
