Airbag Warning Light Failure
AIRBAG SYSTEM (DIAGNOSTICS)
6CHECK POOR CONTACT OF CONNEC-
TORS (AB1) AND (B31).
1) Turn the ignition switch to OFF, disconnect
the battery ground terminal, and wait more
than 20 seconds.
2) Confirm that there is firm contact between
connectors (AB1) and (B31).
Is there poor contact between
connectors (AB1) and (B31)?
Repair the bulk-
head harness or
replace the airbag
main harness with
body harness.
Go to step 7.
7CHECK AIRBAG MAIN HARNESS.
Check the airbag main harness for defect.
Is there any defect in the air-
bag main harness?
Replace the airbag
main harness with
bulkhead harness.
Repair the bulk-
head harness.
Step Check Yes No

Airbag Warning Light Failure
AIRBAG SYSTEM (DIAGNOSTICS)
B: AIRBAG WARNING LIGHT REMAINS OFF
DETECTING CONDITION:
•Fuse No. 5 (in fuse box) is brown out.
•Body harness circuit is open.
•Airbag warning light is faulty.
•Airbag main harness is faulty.
•Airbag control module is faulty.
CAUTION:
•Before diagnosing the airbag system, be sure to turn the ignition switch to OFF, disconnect the
ground terminal from battery, and wait more than 20 seconds before starting to work.
•After replacing the airbag module, seat belt pretensioner, roll connector, control module and sen-
sor, reconnect each part and confirm that the warning light operates properly.
•When inspecting the airbag main harness, disconnect the airbag module connectors and seat belt
pretensioners of the driver’s and passenger’s seats for safety reasons.
