HINT:
When the SRS warning light remains lit up and the DTC is the normal code, this means a voltage source
drops.
This malfunction is not stored in memory by the airbag sensor assembly and if the power source volt-
age returns to normal, the SRS warning light will automatically go out.
When 2 or more codes are indicated, the codes will be displayed in numeral order starting from the
lowest numbered code.
If a code not listed on the chart is displayed, the airbag sensor assembly is faulty.

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

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 ignition switch to ACC or ON and wait at least for 20
seconds.
(b) Clear DTC stored in memory (See page DI±223).
(c) Turn ignition switch to LOCK, and wait at least for 20 se-
conds.
(d) Turn ignition switch to ACC or ON, and wait at least for 20
seconds.
(e) 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 airbag sensor assembly.
OK
