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 LH
position with RH 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 B1154/38 nor B1155/39 are not output.
HINT:
Codes other than code B1154/38 or B1155/39 may be output
at this time, but they are not relevant to this check.
NG Replace airbag sensor assembly
(DTC B1154/38 is output).
NG Replace curtain shield airbag sensor assembly
RH (DTC B1155/39 is output).
OK
From the results of the above inspection, the malfunctioning part can now be considered normal.
