Step
1 CHECK POOR CONTACT.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait for 20 sec-
onds or more.
2) Confirm that firm contact is secured for the
connector between the airbag control module
and the clock.
2 CHECK AIRBAG MAIN HARNESS.
1) Disconnect the connector (AB3) from airbag
control module.
2) Connect the battery ground terminal and
turn the ignition switch to ON.
NOTE:
Neither of ON/OFF illuminates when it is nor-
mal.
3 CHECK AIRBAG MAIN HARNESS.
1) Turn the ignition switch to OFF.
2) Remove the clock and disconnect connec-
tor (i59).
3) Connect the connector (1R) in the test har-
ness R to connector (AB3).
4) Measure the resistance between connec-
tors (2R) and (4R) in the test harness R and
chassis ground.
