Supplemental Restraint System Deactivation and Reactivation

Supplemental Restraint System (SRS) Deactivation and Reactivation





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.

WARNING: The safety belt buckle pretensioner and safety belt retractor pretensioner are pyrotechnic devices. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt retractor pretensioner or safety belt buckle pretensioner.

WARNING: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of the gas generate combustion that is irritating to the skin. Wash your hands with soap and water afterwards.

WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.

WARNING: 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.

WARNING: Air bag modules with discolored or damaged trim covers must be installed new, not repainted.

WARNING: 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 airbag (if equipped) system or a safety belt pretensioner (if equipped) system is being diagnosed or repaired, the supplemental restraint system must be deactivated.

NOTE: Diagnostics may be performed on seat systems other than the side air bag (if equipped) system or the safety belt pretensioner (if equipped) system (lumbar, climate controlled, heated, power seat track) as long as the supplemental restraint system is deactivated.

NOTE: After diagnosing or repairing a seat system the restraint system diagnostic tools must be removed before operating the vehicle over the road.

NOTE: No restraint system diagnostic tool is available for the safety belt buckle pretensioners. If the ignition switch is set to the RUN or START position with the pretensioner electrical connector disconnected, the DTC(s) for an open circuit will be activated.

NOTE: The left-hand drive is shown, the right-hand drive is similar.

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.

Please refer to the appropriate location of the front air bag sensors.
^ The side impact sensors (if equipped) are located at or near the base of the B-pillars and C-pillars.
^ 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).
^ Disconnect the battery ground cable and wait at least one minute.





2. Remove the two steering wheel back cover plugs (one shown).





3. Remove the two driver air bag module bolts (one shown).





4. Remove the driver air bag module.
1 Slide and disengage the driver air bag module electrical connector locking clip.
2 Push in on the two release tabs and disconnect the driver air bag module electrical connector.
3 Disconnect the horn switch electrical connector.
4 Remove the driver air bag module.





5. Attach the restraint system diagnostic tool to the clockspring electrical connector at the top of the steering column.





6. Push in on the glove compartment sides, releasing the stops and lowering it out of the way.





7. Through the glove compartment opening, release the tab and disconnect the passenger air bag module electrical connector.





8. Attach the restraint system diagnostic tool to the vehicle harness side of the passenger air bag electrical connector.

Vehicles without side air curtains

9. CAUTION: Do not deactivate the side air curtain module circuit by removing the side air curtain bridge resistor from the side air curtain electrical connector.

If the side air curtain 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 curtain electrical connector, a low-resistance fault will be generated by the RCM.
