DTC B0116/48 Open in Side Squib (LH) Circuit
(TMC Made)
CIRCUIT DESCRIPTION
The side squib 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 B0116/48 is recorded when an open is detected in the side squib (LH) circuit.

INSPECTION PROCEDURE
1 Prepare for inspection. (See step 1 on page DI±787)
2 Check side squib (LH) circuit.
CHECK:
For the connector (on the side airbag assembly side) between
the side airbag assembly (LH) and the airbag sensor assembly,
measure the resistance between SFL+ and SFL±.

3 Check airbag sensor assembly.
PREPARATION:
(a) Connect the connector to the airbag sensor assembly.
(b) Using a service wire, connect SFL+ and SFL± of the con-
nector (on the side airbag assembly side) between the
side airbag assembly (LH) and the airbag sensor assem-
bly.
(c) Connect negative (±) terminal cable to the battery, and
wait at least 2 seconds.
CHECK:
(a) Turn ignition switch to ACC or ON and wait at least for 20
seconds.
(b) Clear DTC stored in memory.
(See page DI±626)
(c) Turn ignition switch to LOCK, and wait at least for 20 se-
conds.
(d) Turn ignition switch to ACC or ON, and wait at least for 20
seconds.
(e) Check DTC.
(See page DI±626)
OK:
DTC B0116/48 is not output.
