Air Bag(s) Arming and Disarming: Service and Repair
Repowering Procedure
Supplemental Restraint System (SRS) Depowering and Repowering
Repowering Procedure
1. Turn the ignition from OFF to ON.
2. Install RCM fuse 32 (10A) to the SJB and install the cover.
3. WARNING: Make sure no one is in the vehicle and there is nothing blocking or placed in front of any air bag module when the battery is
connected. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.
Connect the battery ground cable.
4. Prove out the SRS as follows:
Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition back ON and monitor the air bag warning indicator with all SRS
components installed and connected. The air bag warning indicator will light continuously for approximately 6 seconds and then turn off. If an air
bag SRS fault is present, the air bag warning indicator will:
-
fail to light.
-
remain lit continuously.
-
flash.
The flashing might not occur until approximately 30 seconds after the ignition 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 a SRS fault exists, a chime will sound
in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator and any SRS fault discovered must be diagnosed and repaired.
Clear all continuous DTCs from the RCM using a scan tool.
