5 Check sub 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 SFR±.
OK:
Resistance: Below 1 W
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 airbag sensor assembly side) be-
tween the airbag sensor assembly and the sub wire harness,
measure the resistance SFR+ and SFR±.
OK:
Resistance: Below 1 W
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.

DTC B0112/41 Short in Side Squib (RH) Circuit
(to Ground) (TMC 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.
