10 Check side airbag sensor assembly (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 side airbag sensor (LH) to the connector that
the side airbag sensor (RH) was connected to.
(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 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 B1140/32 is not output.
HINT:
Codes other than code B1140/32 may be output at this time, but
they are not relevant to this check.
NG Replace side airbag sensor assembly (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.

INSPECTION PROCEDURE
1 Prepare for inspection. (See step 1 on page DI±787)
2 Check wire harness (to B+).
CHECK:
(a) Turn ignition switch to ON.
(b) For the connector (on the airbag sensor assembly side)
between the front airbag sensor (RH) and the airbag sen-
sor assembly, measure the voltage between body ground
and each of SR+ and SR±.
OK:
Voltage: Below 1 V
NG Go to step 8.
OK
3 Check wire harness (to ground).
CHECK:
For the connector (on the airbag sensor assembly side) be-
tween the front airbag sensor (RH) and the airbag sensor as-
sembly, measure the resistance between body ground and
each of SR+ and SR±.
OK:
Resistance: 1 MW or Higher
NG Go to step 9.
OK

CHECK:
For the connector (on the airbag sensor assembly side) be-
tween the front airbag sensor (RH) and the airbag sensor as-
sembly, measure the resistance between SR+ and SR±.
OK:
Resistance: 1 MW or Higher
NG Go to step 10.
OK
5 Check wire harness.
PREPARATION:
Using a service wire, connect SR+ and SR± of the connector
(on the front airbag sensor (RH) side) between the airbag sen-
sor assembly and the front airbag sensor (RH).
CHECK:
For the connector (on the airbag sensor assembly side) be-
tween the front airbag sensor (RH) and the airbag sensor as-
sembly, measure the resistance between SR+ and SR±.
OK:
Resistance: Below 1 W
NG Go to step 11.
