DTC B0118/46 Short in Side Squib LH Circuit (to B+)
CIRCUIT DESCRIPTION
The side squib LH circuit consists of the airbag sensor assembly and the side airbag assembly LH.
It causes the SRS to deploy when the SRS deployment conditions are satisfied.
For details of the function of each component, see OPERATION on page RS-3.
DTC B0118/46 is recorded when a B+ short is detected in the side squib LH circuit.

CHECK:
(a) Turn the ignition switch to ON, and wait at least for 10 se-
conds.
(b) Clear the DTC stored in memory (See page DI-692).
(c) Turn the ignition switch to LOCK, and wait at least for 10
seconds.
(d) Turn the ignition switch to ON, and wait at least for 10 se-
conds.
(e) Check the DTC (See page DI-692).
OK:
DTC B0118/46 is not output.
HINT:
Codes other than code B0118/46 may be output at this time, but
they are not relevant to this check.
NG Replace side airbag assembly LH
(side squib 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. If the malfunctioning part can not be
detected by the simulation method, replace all SRS components including the wire harness.

INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI-692).
2 Check wire harness (to ground).
CHECK:
Measure the resistance between the body ground and LBE+ of
the connector on the airbag sensor assembly side between the
front seat inner belt LH (seat belt buckle switch LH) and the air-
bag sensor assembly.
OK:
Resistance: 1 MW or Higher
NG Go to step 7.
OK
3 Check wire harness (to B+).
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 LBE+
of the connector on the airbag sensor assembly side be-
tween the front seat inner belt LH (seat belt buckle switch
LH) and the airbag sensor assembly.
OK:
Voltage: Below 1 V
NG Go to step 8.
