3 Check airbag sensor assembly.
PREPARATION:
(a) Connect the connector to the airbag sensor assembly.
(b) Connect 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 20 se-
conds.
(b) Clear the DTC stored in memory (See page DI±497).
(c) Turn the ignition switch to LOCK, and wait at least for 20
seconds.
(d) Turn the ignition switch to ON, and wait at least for 20 se-
conds.
(e) Check the DTC (See page DI±497).
OK:
DTC B0100/13 is not output.
HINT:
Codes other than code B0100/13 may be output at this time, but
they are not relevant to this check.
NG Replace airbag sensor assembly.

4 Check D squib.
PREPARATION:
(a) Turn the ignition switch to LOCK.
(b) Disconnect negative (±) terminal cable from the battery,
and wait at least for 90 seconds.
(c) Connect the steering wheel pad connector.
(d) Connect negative (±) terminal cable to the battery, and
wait at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to LOCK, and wait at least for 20
seconds.
(b) Turn the ignition switch to ON, and wait at least for 20 se-
conds.
(c) Clear the DTC stored in memory (See page DI±497).
(d) Turn the ignition switch to LOCK, and wait at least for 20
seconds.
(e) Turn the ignition switch to ON, and wait at least for 20 se-
conds.
(f) Check the DTC (See page DI±497).
OK:
DTC B0100/13 is not output.
HINT:
Codes other than code B0100/13 may be output at this time, but
they are not relevant to this check.
NG Replace steering wheel pad.
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.
