DTC B0113/42 Short in Side Squib (RH) Circuit (to B+)
CIRCUIT DESCRIPTION
The side squib (RH) 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 B0113/42 is recorded when a B+ short is detected in the side squib (RH) circuit.
DTC No. DTC Detecting Condition Trouble Area
S Short circuit in side squib (RH) wire harness (to B+) S Side airbag assembly (RH)
B0113/42 S Side squib (RH) malfunction S Airbag sensor assembly
S Airbag sensor assembly malfunction S Wire harness

R13006 H01068 H17562 DTC B0113/42 is not output.
HINT:
Codes other than code B0113/42 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.
