CHECK DRIVER’S AIRBAG MODULE.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 60 sec-
onds or more.
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) in the test harness Q.
7) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for six seconds and
go off?
Replace the
driver’s airbag
module. <Ref. to
AB-15, Driver’s Air-
bag Module.>

CHECK ROLL CONNECTOR.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 60 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 (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.
Does the airbag warning light
illuminate for six seconds and
go off?
Replace the roll
connector. <Ref. to
AB-26, Roll Con-
nector.>
Go to step

CHECK AIRBAG MAIN HARNESS (DRIV-
ER’S AIRBAG HARNESS).
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 60 sec-
onds or more.
2) Disconnect the airbag resistor from the con-
nectors (2P) and (3P) of test harness P.
3) Remove the console front panel and discon-
nect the connector (AB9).
4) Disconnect the connectors (AB6, AB17,
AB18) from the airbag control module, and con-
nect the connector (1AH) in the test harness
AH.
5) Connect the connector (2AH) in the test har-
ness AH and the connector (1AG) in the test
harness AG.
6) Connect the battery ground terminal and
turn the ignition switch to ON.
7) Measure the voltage between connector
(3AG) in the test harness AG and chassis
ground.
Connector & terminal
(3AG) No. 2 (+) — Chassis ground (–):
(3AG) No. 4 (+) — Chassis ground (–):
Is the voltage less than 1 V?
Go to step
5.
Replace the airbag
main harness
along with body
harness.
