SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEACTIVATION AND REACTIVATIONSpecial Tool(s):
SPECIAL TOOL(S)
DEACTIVATION
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.
- Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment.
- Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment.
- After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of the gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards.
- Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
- The safety belt buckle pretensioner and safety belt retractor pretensioner are pyrotechnic devices. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.
- Vehicle sensor orientation is critical for correct system operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Replace and correctly position the sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed.
- The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
NOTE:
- If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the air bag system must be deactivated.
- Restraint system diagnostic tools MUST be installed in the seat side air bag (if equipped) and safety belt pretensioner (if equipped) electrical connectors.
- After diagnosing or repairing an SRS, the restraint system diagnostic tools must be removed before operating the vehicle over the road.
- After diagnosing or repairing a seat system, the restraint system diagnostic tools must be removed before operating the vehicle over the road.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
All vehicles
1. 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 side impact sensors are located at or near the base of the B-pillar.
To deplete the backup power supply energy, disconnect the battery ground cable, wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
Disconnect the battery ground cable and wait at least one minute.

12. Separate the passenger air bag module from the instrument panel.
1 Remove the passenger air bag module bolts.
2 Placing one hand in the glove box opening, push the passenger air bag module out from the instrument panel.
13. Remove the passenger air bag module.
1 Push in on the retaining tab.
2 Disconnect the passenger air bag module electrical connector.
3 Remove the passenger air bag module.
14. Attach the restraint system diagnostic tool to the vehicle harness side of the passenger air bag electrical connector.
15. Connect the battery ground cable.
16. Move the front seats to their highest and most forward position.
17. 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 side impact sensors are located at or near the base of the B-pillar.
To deplete the backup power supply energy, disconnect the battery ground cable, wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
Disconnect the battery ground cable and wait at least one minute.
Vehicles without side air bags
18. CAUTION: Do not deactivate the side air bag module circuit by removing the side air bag bridge resistor from the side air bag floor electrical connector.
If the side air bag bridge resistor is removed, an open circuit fault will be generated by the restraints control module (RCM).
If a restraint system diagnostic tool is installed at the side air bag floor electrical connector, a low resistance fault will be generated by the RCM.
Vehicles with side air bags
19. Disconnect the passenger seat side air bag module electrical connector, located at the lower rear of the seat cushion pan.
20. Attach the restraint system diagnostic tool to the seat harness side of the passenger seat side air bag module electrical connector.
All vehicles
21. Remove the passenger side front door scuff plate.
22. Remove the passenger side rear door scuff plate.
23. Remove the passenger side B-pillar weather-stripping.
24. Pull out to release the retaining clips and remove the passenger side B-pillar lower trim panel.
25. Pushing in on the release tab, disconnect the passenger safety belt retractor pretensioner electrical connector.
