DTC B0100/13 Short in D Squib Circuit
CIRCUIT DESCRIPTION
The D squib circuit consists of the airbag sensor assembly, spiral cable and steering wheel pad.
It causes the airbag to deploy when the airbag deployment conditions are satisfied.
For details of the function of each component, see Pub. No. RM654U on page RS±2.
DTC B0100/13 is recorded when a short is detected in the D squib circuit.

INSPECTION PROCEDURE
1 Prepare for inspection (See step 1 on page DI±305).
2 Check D squib circuit.
PREPARATION:
Release the airbag activation prevention mechanism of the
connector (on the airbag sensor assembly side) between the
airbag sensor assembly and the spiral cable (See page
DI±223).
CHECK:
For the connector (on the spiral cable side) between the spiral
cable and the steering wheel pad, measure the resistance be-
tween D+ and D±.
OK:
Resistance: 1 MW or Higher
NG Go to step 5.
OK

4 Check D squib.
PREPARATION:
(a) Turn 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 ignition switch to LOCK, and wait at least for 20 se-
conds.
(b) Turn ignition switch to ACC or ON, and wait at least for 20
seconds.
(c) Clear DTC stored in memory (See page DI±223).
(d) Turn ignition switch to LOCK, and wait at least for 20 se-
conds.
(e) Turn ignition switch to ACC or ON, and wait at least for 20
seconds.
(f) Check DTC (See page DI±223).
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.

5 Check spiral cable.
PREPARATION:
(a) Disconnect the connector between the airbag sensor as-
sembly and the spiral cable.
(b) Release the airbag activation prevention mechanism of
the spiral cable connector on the airbag sensor assembly
side (See page DI±223).
CHECK:
For the connector (on the spiral cable side) between the spiral
cable and the steering wheel pad, measure the resistance be-
tween D+ and D±.
OK:
Resistance: 1 MW or Higher
NG Repair or replace spiral cable.
OK
6 Check harness between airbag sensor assembly and spiral cable.
PREPARATION:
Release the airbag activation prevention mechanism of the
connector (on the airbag sensor assembly side) between the
airbag sensor assembly and the spiral cable (See page
DI±223).
CHECK:
For the connector (on the spiral cable side) between the airbag
sensor assembly and the spiral cable, measure the resistance
between D+ and D±.
OK:
Resistance: 1 MW or Higher
NG Repair or replace harness or connector be-
tween airbag sensor assembly and spiral cable.
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.
