DTC B0115/47 Short in Side Squib LH Circuit
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 B0115/47 is recorded when a short is detected in the side squib LH circuit.

INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI-923).
2 Check floor No. 1 wire (side squib LH circuit).
PREPARATION:
Release the airbag activation prevention mechanism built in the
connector of the floor No. 1 wire on the airbag sensor assembly
side (See page DI-692).
CHECK:
Measure the resistance between SFL+ and SFL- of the floor
No. 1 wire connector on the side airbag assembly LH (side
squib LH) side.
OK:
Resistance: 1 MW or Higher
NG Repair or replace floor No. 1 wire.
OK

3 Check airbag sensor assembly.
PREPARATION:
(a) Connect the connector to the airbag sensor assembly.
(b) Connect the negative (-) terminal cable to the battery,
and wait at least for 2 seconds.
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 B0115/47 is not output.
HINT:
Codes other than code B0115/47 may be output at this time, but
they are not relevant to this check.
NG Replace airbag sensor assembly.
OK

4 Check side squib LH.
PREPARATION:
(a) Turn the ignition switch to LOCK.
(b) Disconnect the negative (-) terminal cable from the bat-
tery, and wait at least for 90 seconds.
(c) Connect the side airbag assembly LH (side squib LH)
connector.
(d) Connect the negative (-) terminal cable to the battery,
and wait at least for 2 seconds.
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 B0115/47 is not output.
HINT:
Codes other than code B0115/47 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.
