DTC B0118/46 Short in Side Squib (LH) Circuit (to B)
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-3.
DTC B0118/46 is recorded when a B+ short is detected in the side squib (LH) circuit.

seconds.
(d) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(e) Check the DTC (See page DI-349).
OK:
DTC B0118/46 is not output.

CHECK:
(a) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(b) Clear the DTC stored in memory
(See step 5 on page DI-349).
(c) Turn the ignition switch to LOCK, and wait at least for 20
seconds.
(d) Turn the ignition switch to ACC or ON, and wait at least
for 20 seconds.
(e) Check the DTC (See page DI-349).
OK:
DTC B0118/46 is not output.

Codes other than code B0118/46 may be output at this time, but
they are not relevant to this check.
NG Replace side airbag assembly (LH).
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.
