Supplemental Restraint System (SRS) Depowering and Repowering



Supplemental Restraint System (SRS) Depowering and Repowering







Depowering Procedure

WARNING:
- Never probe the electrical connectors on airbag, Safety Canopy(R) or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.
- 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.
- 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.
- 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 OFF.
3. At the Central Junction Box (CJB), located behind the glove box, remove RCM fuse 20 (10A) from the CJB. For additional information, refer to the Wiring Diagrams manual.
4. Turn the ignition ON and monitor the air bag warning indicator for at least 30 seconds. The air bag warning indicator flashes once, then remains illuminated continuously (no flashing) if the correct RCM fuse has been removed. If the air bag warning indicator does not remain illuminated 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 supplemental restraint system (SRS) component and before servicing, removing, installing, adjusting or striking components near the front or side impact sensors or the restraints control module (RCM). Nearby components include doors, instrument panel, console, door latches, strikers, seats and hood latches. Refer to the Description and Operation portion of 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.

Repowering Procedure

Vehicles with keyed ignition (vehicles with ignition switch)

1. Turn the ignition from OFF to ON.
2. Install RCM fuse 20 (10A) to the CJB.

3. WARNING: Make sure no one is in the vehicle and there is nothing blocking or placed in front of any airbag 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 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 indicates the fault in one of the following ways:
- 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 fault discovered.

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

Vehicles with Intelligent Access (IA) (vehicles with push button start system)

5. Install RCM fuse 20 (10A) to the CJB and install the cover.
6. Remove the Smart Keyless Ignition Relay (CJB relay 7).







7. Install a fused (15A) jumper wire between Smart Keyless Entry Ignition Relay (CJB relay 7) socket pins 3 and 5 as shown..







8. WARNING: Make sure no one is in the vehicle and there is nothing blocking or placed in front of any airbag 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.

9. Remove the fused jumper wire from the CJB.
10. Install the Smart Keyless Ignition Relay (CJB relay 7).
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 indicates the fault in one of the following ways:
- 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 will sound in a pattern of 5 sets of 5 beeps. If this occurs, the diagnose and repair the air bag warning indicator and any SRS fault discovered.
Clear all RCM and OCSM CMDTCs.
