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.

Airbag 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±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.
OK

2 Check source voltage.
PREPARATION:
Connect negative (±) terminal cable to the battery.
CHECK:
(a) Turn ignition switch ON.
(b) Measure the voltage 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
3 Does SRS warning light turn off?
PREPARATION:
(a) Turn ignition switch to LOCK.
(b) Connect the steering wheel pad connector.
(c) Connect the front passenger airbag assembly connector.
(d) Connect the airbag sensor assembly connectors.
(e) Connect the side airbag assembly connectors.
(f) Connect the seat belt pretensioner connectors.
(g) Connect the side airbag sensor assembly connectors.
(h) Connect the front airbag sensor connectors.
(i) Turn ignition switch to ON.
CHECK:
Operate electric system (defogger, wiper, headlight, heater
blower, etc.) and check that SRS warning light goes off.
NO Check for DTCs. If a DTC is output, perform trou-
bleshooting for the DTC. If a normal code is out-
put, replace airbag sensor assembly.
YES
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.
