Depowering Procedure

WARNING:
- Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module.This will reduce the risk of injury in the event of an accidental deployment.
- Never probe the connectors on the air bag module.Doing so can result in air bag deployment, which can result in personal injury.
- To reduce the risk of personal injury, do not use any memory saver devices.

NOTE:
- The air bag warning lamp illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
- 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 switch to OFF.
3. At the smart power distribution junction box (SPDJB), located in the RH lower kick panel, remove the cover and the restraints control module (RCM) fuse 32 (10A) from the SPDJB.
4. Turn the ignition ON and visually monitor the air bag warning indicator for at least 30 seconds.The air bag warning indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed.If the air bag warning indicator does not remain lit continuously, remove the correct RCM fuse before proceeding.
5. Turn the ignition switch to OFF.

6. WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.

The front impact severity sensor is located on the bottom of the radiator support bracket.

The front door side impact sensors (if equipped) are located in the first row doors, behind the door trim panel.

The C-pillar side impact sensors (if equipped) are located on the C-pillar.

To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). Failure to follow these instructions may increase the risk of personal injury or death in a crash.

Disconnect the battery ground cable (14301) and wait at least one minute.

Repowering Procedure
1. Make sure that all supplemental restraint system (SRS) components are connected.
2. Turn the ignition switch from OFF to ON.
3. Install restraints control module (RCM) fuse 32 (10A) to the SPDJB and close the cover.

4. WARNING: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the battery ground cable is connected.Failure to follow these instructions may increase the risk of personal injury or death in a crash.

Connect the battery ground cable.

5. Prove out the SRS as follows:

Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag warning indicator with the air bag modules installed.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 either:
- fail to light.
- remain lit continuously.
- flash.

The air bag warning indicator may not illuminate 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.

Clear all continuous memory DTCs from the restraints control module using a scan tool.
