5 Check sub wire harness.
PREPARATION:
Disconnect the sub wire harness connector on the airbag sen-
sor assembly side.
CHECK:
(a) Turn ignition switch to ON.
(b) For the connector (on the sub wire harness side) between
the side airbag assembly and the sub wire harness, mea-
sure the voltage between SFR+ and body ground.
OK:
Voltage: 0 V
NG Repair or replace sub wire harness.
OK
6 Check harness between airbag sensor assembly and sub wire harness.
CHECK:
(a) Turn ignition switch to ON.
(b) For the connector (on the sub wire harness side) between
the sub wire harness and the airbag sensor assembly,
measure the voltage between SFR+ and body ground.
OK:
Voltage: 0 V
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.

DTC B0115/47 Short in Side Squib (LH) Circuit
(TMC Made)
CIRCUIT DESCRIPTION
The side squib (LH) circuit consists of the airbag sensor assembly and 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±2.
DTC B0115/47 is recorded when a short is detected in the side squib (LH) circuit.
