DTC 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 sensors, judges whether or not the SRS must be activated, and diagnosis
system malfunction.
DTC 31 is recorded when occurrence of a malfunction in the airbag sensor\
assembly is detected.
DTC No.DTC Detection ConditionTrouble Area
31 Airbag sensor assembly malfunctionAirbag sensor assembly
INSPECTION PROCEDURE
HINT:
When a malfunction code other than code 31 is displayed at the same time, fi\
rst repair the malfunction indi-
cated by the malfunction code other than code 31.
1 Preparation (See step 1 on page DI−271).
2 Check voltage at IG2 and ACC of airbag sensor assembly.
PREPARATION:
Turn ignition switch ON.
CHECK:
Measure voltage between terminals IG2 and ACC of airbag
sensor assembly and body ground.
OK:
Voltage: Below 16 V
NG Check battery and charging system (See page CH−2).
OK

1996 LAND CRUISER (RM451U)
INSPECTION PROCEDURE
1 Preparation.
PREPARATION:
(a) Disconnect negative ( −) terminal cable from the battery,
and wait at least 90 seconds.
(b) Remove steering wheel pad (See page SR−11).
(c) Disconnect connector of front passenger airbag assem- bly (See page RS−22 ).
(d) Disconnect connector of airbag sensor assembly (See page RS−33 ).
CAUTION:
Store the steering wheel pad with the front surface facing
upward.
2 Check source voltage.
PREPARATION:
(a) Connect negative ( −) terminal cable to battery.
(b) Turn ignition switch ON.
CHECK:
Measure voltage at IG2 or ACC on sensor and operate electric
system. (defogger, wiper, headlight, heater blower, etc.)
OK:
Voltage: 10 − 14 V
NG Check the harness between battery and airbag sensor assembly, and check the battery and
charging system.
