4 Check curtain shield squib RH.
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 curtain shield airbag assembly RH (curtain
shield squib RH) connector.
(d) 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:
DTC B1161/84 is not output.
HINT:
Codes other than code B1161/84 may be output at this time, but
they are not relevant to this check.
NG Replace curtain shield airbag assembly RH
(curtain shield squib RH).
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 B1162/81 Short in Curtain Shield Squib RH
Circuit (to Ground)
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 B1162/81 is recorded when ground short is detected in the curtain shield squib RH circuit.
