7 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 front airbag sensor RH position with LH posi-
tion.
(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 B1148/36 nor B1149/37 not output.
HINT:
Codes other than code B1149/37 or B1148/36 may be output
at this time, but they are not relevant to this check.
NG Replace airbag sensor assembly
(DTC B1149/37 is output).
NG Replace front airbag sensor LH
(DTC B1148/36 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.
