Step
1 CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the airbag control module and the
driver's airbag module.
2 CHECK DRIVER'S AIRBAG MODULE.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than 20
seconds.
2) Remove the driver's airbag module.
3) Connect the connector (AB38) to the con-
nector (1N) in the test harness N.
4) Connect the airbag resistor to the connector
(2N) of test harness N.
5) Connect the connector (1Q) in the test har-
ness Q to connector (AB37).
6) Connect the airbag resistor to the connector
(2Q) of test harness Q.
7) Connect the battery ground terminal and
turn the ignition switch to ON.
3 CHECK ROLL CONNECTOR.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than 20
seconds.
2) Disconnect the test harness N from connec-
tor (AB38).
3) Disconnect the test harness Q from connec-
tor (AB37).
4) Remove the instrument panel lower cover
and disconnect the connector (AB7) from
(AB2).
5) Connect the connector (1P) in the test har-
ness P to connector (AB2).
6) Connect the airbag resistor to the connec-
tors (2P) and (3P) of test harness P.
7) Connect the battery ground terminal and
turn the ignition switch to ON.
4 CHECK AIRBAG MAIN HARNESS (DRIV-
ER'S AIRBAG HARNESS).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than 20
seconds.
2) Disconnect the airbag resistor from the con-
nectors (2P) and (3P) of test harness P.
3) Remove the console side cover lower on the
passenger's side and disconnect the connec-
tors (AB10) and (AB9).
4) Disconnect the connector (AB6) from the
airbag control module, and connect the connec-
tor (1U) in the test harness U.
5) Connect the battery ground terminal and
turn the ignition switch to ON. (Engine OFF)
6) Measure the voltage between connector
(2U) in the test harness U and chassis ground.
Connector & terminal
(2U) No. 4 (+) — Chassis ground (–):
(2U) No. 2 (+) — Chassis ground (–):
(2U) No. 8 (+) — Chassis ground (–):
(2U) No. 12 (+) — Chassis ground (–):
Diagnostic Chart with Trouble Code
Is there poor contact?

illuminate for 6 seconds and go
off?
Does the airbag warning light
illuminate for 6 seconds and go
off?
