3 Check airbag sensor assembly.
PREPARATION:
(a) Connect the connector to the airbag sensor assembly.
(b) Using a service wire, connect D+ and D- of the orange
connector on the steering wheel pad (D squib) side be-
tween the airbag sensor assembly and the steering wheel
pad (D squib).
(c) 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 B0101/14 is not output.
HINT:
Codes other than code B0101/14 may be output at this time, but
they are not relevant to this check.
NG Replace airbag sensor assembly.
OK

4 Check D squib.
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 steering wheel pad (D squib) to the spiral
cable.
(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 B0101/14 is not output.
HINT:
Codes other than code B0101/14 may be output at this time, but
they are not relevant to this check.
NG Replace steering wheel pad (D squib).
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 B0102/11 Short in D Squib Circuit (to Ground)
CIRCUIT DESCRIPTION
The D squib circuit consists of the airbag sensor assembly, the spiral cable and the steering wheel pad.
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 B0102/11 is recorded when a ground short is detected in the D squib circuit.

WIRING DIAGRAM
See page DI-71 1.
INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI-923).
2 Check D squib circuit.
CHECK:
