1
CHECK DRIVER’S AIRBAG MODULE.
1) Turn the ignition switch OFF, disconnect the
battery ground cable, and wait more than 20
seconds.
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 connector
(2N) in the test harness N.
5) Connect the connector (1Q) in the test har-
ness Q to connector (AB37).
6) Connect the airbag resistor to connector
(2Q) in the test harness Q.
7) Connect the battery ground cable and turn
the ignition switch to ON.
Does the airbag warning light
illuminate for 6 seconds and go
off?
Replace the
driver’s airbag
module. <Ref. to
AB-16, Driver’s
Airbag Module.>
Go to step 2.
2
CHECK ROLL CONNECTOR.
1) Turn the ignition switch OFF, disconnect the
battery ground cable, and wait more than 20
seconds.
2) Disconnect the test harness N from con-
nector (AB38).
3) Disconnect the test harness Q from con-
nector (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 connectors
(2P) and (3P) in the test harness P.
7) Connect the battery ground cable and turn
the ignition switch to ON.
Does the airbag warning light
illuminate for 6 seconds and go
off?
Replace the roll
connector. <Ref. to
AB-25, Roll Con-
nector.>
Go to step 3.

CHECK AIRBAG MAIN HARNESS (DRIV-
ER’S AIRBAG HARNESS).
1) Turn the ignition switch OFF, disconnect the
battery ground cable, and wait more than 20
seconds.
2) Disconnect the airbag resistor from con-
nectors (2P) and (3P) in the test harness P.
3) Remove the instrument panel side cover on
passenger’s side and disconnect the connec-
tors (AB10) and (AB9).
4) Disconnect the connector (AB6) from air-
bag control module, and connect the connector
(1U) in the test harness U.
5) Measure the resistance between connector
(2U) in the test harness U and connectors (2P)
and (3P) in the test harness P.
Connector & terminal
(2U) No. 2 — (2P) No. 1:
(2U) No. 4 — (2P) No. 2:
(2U) No. 8 — (3P) No. 3:
(2U) No. 12 — (3P) No. 4:
Is the resistance less than 10
Ω?
Go to step 4.
Replace the airbag
main harness with
body harness.
