DTC B0112/41 Short in Side Squib (RH) Circuit
(to Ground) (TMMK Made)
CIRCUIT DESCRIPTION
The side squib circuit consists of the airbag sensor assembly and side airbag assembly (RH).
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±2.
DTC B0112/41 is recorded when ground short is detected in the side squib (RH) circuit.

INSPECTION PROCEDURE
1 Prepare for inspection. (See step 1 on page DI±787)
2 Check side squib (RH) circuit.
CHECK:
For the connector (on the side airbag assembly side) between
the side airbag assembly (RH) and the airbag sensor assembly,
measure the resistance between SFR+ and body ground.
OK:
Resistance: 1 MW or Higher
NG Go to step 5.
OK

3 Check airbag sensor assembly.
PREPARATION:
(a) Connect the connector to the airbag sensor assembly.
(b) Using a service wire, connect SFR+ and SFR± of the con-
nector (on the side airbag assembly side) between the
side airbag assembly (RH) and the airbag sensor assem-
bly.
(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 B0112/41 is not output.
HINT:
Codes other than code B0112/41 may be output at this time, but
they are not relevant to this check.
NG Replace airbag sensor assembly.
OK

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 assembly (RH) connector.
(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 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 B0112/41 is not output.
HINT:
Codes other than code B0112/41 may be output at this time, but
they are not relevant to this check.
NG Replace side airbag assembly (RH).
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.

PREPARATION:
Disconnect the sub wire harness connector on the airbag sen-
sor assembly side.
CHECK:
For the connector (on the sub wire harness side) between the
side airbag assembly and the sub wire harness, measure the
resistance between SFR+ and body ground.
OK:
Resistance: 1MW or Higher
NG Repair or replace sub wire harness.
OK
6 Check harness between airbag sensor assembly and sub wire harness.
CHECK:
For the connector (on the sub wire harness side) between the
sub wire harness and the airbag sensor assembly, measure the
resistance between SFR+ and body ground.
OK:
Resistance: 1MW or Higher
NG Repair or replace harness or connector be-
tween airbag sensor assembly and sub wire
harness.
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.
