7. RELEASE METHOD OF AIRBAG ACTIVATION PRE-
VENTION MECHANISM
An airbag activation prevention mechanism is built into the con-
nector for the squib circuit of the SRS.
When release of the airbag activation prevention mechanism is
directed in the troubleshooting procedure, as shown in the il-
lustration of the connectors on the next pages, insert paper
which is the same thickness as the male terminal, between the
terminal and the short spring.
CAUTION:
Never release the airbag activation prevention mechanism
on the steering wheel pad connector.
NOTICE:
Do not release the airbag activation prevention mech-
anism unless specifically directed by the trouble-
shooting procedure.
If the inserted paper is too thick the terminal and short
spring may be damaged, so always use paper with
the same thickness as the male terminal.

CIRCUIT INSPECTION
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 OPERATION 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±787)
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±626)
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±626)
(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±626)
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.
