PREPARATION:
(a) Disconnect the side airbag sensor assembly (LH).
(b) Using a service wire, connect SSL+ and ESL of the con-
nector (on the side airbag sensor assembly side) between
the side airbag sensor assembly (LH) and the airbag sen-
sor assembly.

8 Is DTC B1141/33 out put again?
PREPARATION:
(a) Connect the connector to the side airbag sensor assem-
bly (LH).
(b) Connect the connector to the airbag sensor assembly.
(c) 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 B1141/33 is not output.
HINT:
Codes other than code B1141/33 may be output at this time, but
they are not relevant to this check.
NO Go to step 9.
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.

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.
