Turn the ignition switch from the OFF to the ON position and visually monitor the air bag warning indicator with all supplemental restraint system (SRS) components connected. The instrument cluster (IC) will illuminate the air bag warning indicator continuously for approximately 6 seconds and then turn off. If an SRS fault is present, the air bag warning indicator will:

fail to light.
remain lit continuously.
flash.

The air bag warning indicator may not illuminate to indicate a fault is present until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the RCM to complete the testing of the SRS. If the air bag warning indicator is inoperative and an SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator will need to be repaired before diagnosis can continue.
