DTC B1100/31 Airbag Sensor Assembly Malfunction
CIRCUIT DESCRIPTION
The airbag sensor assembly consists of the 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.
DTC No.DTC Detecting ConditionTrouble Area
B1100/31Airbag sensor assembly malfunctionAirbag sensor assembly
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-923).
2 Check airbag sensor assembly.
PREPARATION:
Connect the negative (-) terminal cable to the battery, and wait
at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to ON.
(b) Measure the voltage between the body ground and IG2
of the dash wire connector on the airbag sensor assembly
side.
OK:
Voltage: 10 - 14 V
NG Check that an abnormality occurs on the battery
and charging system.

on the airbag sensor assembly and operate electric sys-
tem (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
3 Check airbag sensor assembly connector.
CHECK:
Measure the resistance between the body ground and each of
E1 and E2 of the airbag sensor assembly connector.
OK:
Resistance: 0 W (Continuity)
NG Repair or replace airbag sensor assembly con-
nector.
