Supplemental Restraint System (SRS) Depowering and Repowering
Supplemental Restraint System (SRS) Depowering and Repowering
Depowering Procedure
WARNING: Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.
WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.
WARNING: 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 Restraints Control Module (RCM) fuse is removed and the ignition is ON.
NOTE: The Supplemental Restraint System (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 to OFF.
3. At the Central Junction Box (CJB), located below the LH side of the instrument panel, remove RCM (Restraints Control Module) fuse 162 (7.5A) from the CJB (Central Junction Box). For additional information, refer to the Wiring Diagrams. Electrical Diagrams
4. Turn the ignition ON and monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no flashing) if the correct fuse has been removed. If the air bag warning indicator does not remain lit continuously, remove the correct RCM (Restraints Control Module) fuse before proceeding.
5. Turn the ignition OFF.
6. WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction 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.
Repowering Procedure
1. Turn the ignition from OFF to ON.
2. Install the RCM (Restraints Control Module) fuse 162 (7.5A) to the CJB (Central Junction Box).
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 (Supplemental Restraint System) 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 will light continuously for approximately 6 seconds and then turn off. If an air bag SRS (Supplemental Restraint System) fault is present, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash.
The air bag warning indicator may not illuminate 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 (Restraints Control Module) to complete the testing of the SRS (Supplemental Restraint System). If the air bag warning indicator is inoperative and a SRS (Supplemental Restraint System) 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 (Supplemental Restraint System) fault discovered must be diagnosed and repaired.
Clear all CMDTCs (Continuous Memory Diagnostic Trouble Codes) from the RCM (Restraints Control Module) and OCSM (Occupant Classification System Module) using a scan tool.
