Depowering
WARNING:
- Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.
- Never probe the electrical connectors on air bag, Safety Canopy(R) or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
- To reduce the risk of accidental deployment, do not use any memory saver devices. Failure to follow this instruction may result in serious personal injury or death.
NOTE:
- The air bag warning indicator illuminates when the correct RCM fuse is removed and the ignition is ON.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
1. Turn all vehicle accessories OFF.
2. Turn the ignition OFF.
3. At the BCM, located in the LH lower kick panel, remove the lower kick panel fuse cover and the RCM fuse 37 (10A) from the BCM. For additional information, Refer to Wiring Diagrams Cell 11 for schematic and connector information.
4. Turn the ignition ON and monitor the air bag warning indicator for at least 30 seconds. The air bag warning indicator remains lit continuously (no flashing) if the correct RCM fuse is removed. If the air bag warning indicator is not lit continuously, remove the correct RCM fuse before proceeding.
5. Turn the ignition OFF.
6. WARNING: Always deplete the backup power supply before repairing or installing any new front or side air bag SRS component and before servicing, removing, installing, adjusting or striking components near the front or side impact sensors or the RCM. Nearby components include doors, instrument panel, console, door latches, strikers, seats and hood latches. Refer to the Description and Operation portion of refer to Restraints for location of the RCM and impact sensor(s). To deplete the backup power supply energy, disconnect the battery ground cable and wait at least 1 minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). Failure to follow these instructions may result in serious personal injury or death in the event of an accidental deployment.
Disconnect the battery ground cable and wait at least one minute.

WARNING:
- Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.
- Never probe the electrical connectors on air bag, Safety Canopy(R) or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
- To reduce the risk of accidental deployment, do not use any memory saver devices. Failure to follow this instruction may result in serious personal injury or death.
NOTE:
- The air bag warning indicator illuminates when the correct RCM fuse is removed and the ignition is ON.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
1. Install RCM fuse 37 (10A) to the BCM and close the cover.
2. Remove the run/start relay from the BJB.
3. Install a 30A fused jumper wire in BJB run/start relay cavities 3 and 5, as shown.
4. 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.
5. Wait at least 30 seconds, then remove the fused jumper wire from the BJB.
6. Install the run/start relay in the BJB and install the cover.
7. Prove out the SRS: 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 a SRS fault is present, the air bag warning indicator:
- fails to light.
- remains lit continuously.
- flashes.
The flashing may 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.
8. Clear all CMDTCs from the RCM and OCSM using a scan tool.
