DTC B0117/45 Short in Side Squib (LH) Circuit
(to Ground)
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 B0117/45 is recorded when a ground short is detected in the side squib (LH) circuit.

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.
