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-3.
DTC B0113/42 is recorded when a B+ short is detected in the side squib (RH) circuit.

INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI-349).
2 Check side squib (RH) circuit.
CHECK:
(a) Turn the ignition switch to ON.
(b) For the connector (on the airbag sensor assembly side)
between the side airbag assembly (RH) and the airbag
