12.Airbag Warning Light Failure
A: AIRBAG WARNING LIGHT REMAINS ON
DETECTING CONDITION:
•Airbag warning light is faulty.
•Airbag control module to airbag warning light circuit is shorted or open.
•Grounding circuit is faulty.
•Airbag control module is faulty.
•Connection of (AB1) and (B31) is improper.
•Connection of (AB6) to airbag control module is improper.
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.
