Air Bag(s) Arming and Disarming: Service and Repair
Prove Out Procedure
Turn the ignition switch from the OFF to the RUN position and visually monitor the air bag indicator with the air bag modules and safety belt
pretensioners or restraint system diagnostic tools installed. The air bag indicator will light continuously for approximately six seconds and then turn off.
If an air bag Supplemental Restraint System (SRS) fault is present, the air bag indicator will either:
^
fail to light.
^
remain lit continuously.
^
flash.
The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the RUN position. This is the
time required for the Restraints Control Module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and an SRS fault exists,
a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator will need to be repaired before diagnosis can continue.
