Step
1 CHECK POOR CONTACT OF CONNECTORS.
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 for 20 sec-
onds or more.
2) Remove the driver's airbag module.
3) Connect the connector (1N) in the test har-
ness N to the connector (AB38).
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) in the 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 for 20 sec-
onds or more.
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 (AB26) 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 for 20 sec-
onds or more.
2) Disconnect the airbag resistor from the con-
nectors (2P) and (3P) of test harness P.
3) Remove the instrument panel side cover on
the passenger's side and disconnect connec-
tors (AB4) and (AB27).
4) Disconnect connector (AB3) from airbag
control module, and connect connector (1R) in
the test harness U.
5) Measure the resistance between connector
(2R) in the test harness R and connectors (2P)
and (3P) in the test harness P.
