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:
Release the airbag activation prevention mechanism built in the
connector of the floor No. 1 wire on the airbag sensor assembly
side (See page DI-692).
CHECK:
Measure the resistance between ICL+ and ICL- of the floor No.
1 wire connector on the curtain shield airbag assembly LH (cur-
tain shield squib LH) side.
OK:
Resistance: 1 MW or Higher
NG Repair or replace floor No. 1 wire.
OK

3 Check airbag sensor assembly.
PREPARATION:
(a) Connect the connector to the airbag sensor assembly.
(b) Connect the negative (-) terminal cable to the battery,
and wait at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to ON, and wait at least for 10 se-
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 or ON, and wait at least for 10 se-
conds.
(e) Check the DTC (See page DI-692).
OK:
DTC B1165/87 is not output.

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 B1165/87 is not output.
HINT:
Codes other than code B1165/87 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).
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.

DTC B1166/88 Open in Curtain Shield Squib LH
Circuit
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 B1166/88 is recorded when an open is detected in the curtain shield squib LH circuit.
