12 Check curtain shield airbag assembly LH (curtain shield airbag LH squib).
PREPARATION:
(a) Turn the ignition switch to the LOCK position.
(b) Disconnect the negative (±) terminal cable from the bat-
tery, and wait for at least 90 seconds.
(c) From the step 9:
Disconnect the service wire from connector ºCº.
(d) Connect the connector to the curtain shield airbag as-
sembly LH.
(e) Connect the negative (±) terminal cable to the battery,
and wait for at least 2 seconds.
CHECK:
(a) Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
(b) Clear the DTCs stored in memory (see page DI±1147).
(c) Turn the ignition switch to the LOCK position.
(d) Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
(e) Check the DTCs (see page DI±1147).
OK:
DTC B1835, B1836, B1837 or B1838 is not output.
HINT:
Codes other than DTC B1835, B1836, B1837 and B1838 may
be output at this time, but they are not related to this check.
NG Replace curtain shield airbag assembly LH
(see page RS±71).
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 (see page DI±1137).
HINT:

Perform the simulation method by selecting the check mode with the hand±held tester (see page
DI±1151).

After selecting the check mode, perform the simulation method by wiggling each connector of the air-
bag system or driving the vehicle on a city or rough road (see page DI±1151).
