Repowering Procedure

Vehicles with keyed ignition (vehicles with ignition switch) 

1. Turn the ignition from OFF to ON.
2. Install RCM  fuse 41 (7.5A) to the BCM  and close the cover.
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.
3. 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 to ON and monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator illuminates continuously for approximately 6 seconds and then turns off. If a 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 OFF to ON. 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 sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the air bag warning indicator and any SRS  faults.

   Clear all continuous DTCs from the RCM  and Occupant Classification System Module (OCSM) using a scan tool.

   Vehicles with keyless ignition (vehicles with push-button start system [Intelligent Access (IA)]) 

5. Install RCM  fuse 41 (7.5A) to the BCM  and install the cover.
6. Remove the run/start relay from the Battery Junction Box (BJB).

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.
8. Connect the battery ground cable.
9. Wait at least 30 seconds, then remove the fused jumper wire from the BJB  .
10. Install the run/start relay in the BJB  and install the cover.
11. Prove out the SRS  as follows:

    With the ignition OFF, wait 10 seconds, then turn the ignition ON and monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator illuminates continuously for approximately 6 seconds and then turns off. If an air bag SRS  fault is detected, 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 OFF to ON. This is the time required to complete testing of the SRS  . If the air bag warning indicator is inoperative and a SRS  fault exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the air bag warning indicator and any SRS  faults.

12. Clear all CMDTCs  from the RCM  and OCSM  .
