8 Check airbag sensor assembly.
PREPARATION:
(a) Turn the ignition switch to LOCK.
(b) Disconnect the negative (-) terminal cable from the bat-
tery, and wait at least for 90 seconds.
(c) Connect the connector to the airbag sensor assembly.
(d) Change the curtain shield airbag sensor assembly RH
position with LH position.
(e) 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 to ON, and wait at least for 10 se-
conds.
(e) Check the DTC (See page DI-692).
OK:
Neither DTC B1155/39 nor B1154/38 are not output.
HINT:
Codes other than code B1155/39 B1154/38 may be output at
this time, but they are not relevant to this check.
NG Replace airbag sensor assembly
(DTC B1155/39 is output).
NG Replace curtain shield airbag sensor assembly
LH (DTC B1154/38 is output).
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 B1160/83 Short in Curtain Shield Squib RH
Circuit
CIRCUIT DESCRIPTION
The curtain shield squib RH circuit consists of the airbag sensor assembly and the curtain shield airbag as-
sembly RH.
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 B1110/83 is recorded when a short is detected in the curtain shield squib RH circuit.

INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI-923).
2 Check floor No. 2 wire (curtain shield squib RH circuit).
PREPARATION:
Release the airbag activation prevention mechanism built in the
connector of the floor No. 2 wire on the airbag sensor assembly
side (See page DI-692).
CHECK:
Measure the resistance between ICR+ and ICR- of the floor
No. 2 wire connector on the curtain shield airbag assembly RH
(curtain shield squib RH) side.
OK:
Resistance: 1 MW or Higher
NG Repair or replace floor No. 2 wire.
OK
