4 Check P/T squib (LH).
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 seat belt pretensioner (LH) 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 step 5 on 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 B0138/72 is not output.
HINT:
Codes other than code B0138/72 may be output at this time, but
they are not relevant to this check.
NG Replace seat belt pretensioner (LH).
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.

DTC B1100/31 Airbag Sensor Assembly Malfunction
CIRCUIT DESCRIPTION
The airbag sensor assembly consists of a airbag sensor, safing sensor, drive circuit, diagnosis circuit and
ignition control, etc.
It receives signals from the airbag sensor, judges whether or not the SRS must be activated, and detects
diagnosis system malfunction.
DTC B1100/31 is recorded when occurrence of a malfunction in the airbag sensor assembly is detected.

INSPECTION PROCEDURE
HINT:
When a malfunction code other than code B1100/31 is displayed at the same time, first repair the malfunction
indicated by the malfunction code other than code B1100/31.
1 Prepare for inspection. (See step 1 on page DI±787)
2 Check voltage at IG2 and ACC of airbag sensor assembly.
CHECK:
(a) Turn ignition switch to ON.
(b) Measure the voltage between body ground and terminals
each of IG2 and ACC of the airbag sensor assembly con-
nector.
OK:
Voltage: 10 ± 14 V
NG Check that an abnormality occurs on the battery
and charging system.

Malfunction
CIRCUIT DESCRIPTION
The side airbag sensor assembly (RH) consists of the safing sensor, diagnosis circuit and lateral decelera-
tion sensor, etc.
It receives signals from the lateral deceleration sensor, judges whether or not the SRS must be activated,
and diagnosis system malfunction.
DTC B1140/32 is recorded when occurrence of a malfunction in the side airbag sensor assembly (RH) is
detected.
