conds.
(b) Clear the DTC stored in memory (See page DI-692).
(c) Turn the ignition switch to LOCK, and wait at least for 10
seconds.
(d) Turn the ignition switch to ON, and wait at least for 10 se-
conds.
(e) Check the DTC (See page DI-692).
OK:
DTC B1166/88 is not output.
HINT:
Codes other than code B1166/88 may be output at this time, but
they are not relevant to this check.
NG Replace curtain shield airbag assembly LH
(curtain shield squib LH).

DTC B1168/86 Short in Curtain Shield Squib LH
Circuit (to B+)
CIRCUIT DESCRIPTION
The curtain shield squib LH circuit consists of the airbag sensor assembly and the curtain shield airbag as-
sembly 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 B1168/86 is recorded when a B+ short is detected in the curtain shield squib LH circuit.

See page DI-869.
INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI-923).
2 Check floor No. 1 wire (curtain shield squib LH circuit).
PREPARATION:
Connect the negative (-) terminal cable to the battery, and wait
at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to ON.
(b) Measure the voltage between the body ground and ICL+
of the floor No. 1 wire connector on the curtain shield air-
bag assembly LH (curtain shield squib LH) side.
OK:
Voltage: Below 1 V
NG Repair or replace floor No. 1 wire.
OK
