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: 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.

WARNING: Do not set a live air bag module down with the trim cover face down. This win reduce the risk of injury in the event of an accidental deployment.

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: Vehicle sensor orientation is critical for proper 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 properly position the sensor or any other damaged Supplemental Restraint System (SRS) components whether or not the air bag is deployed.

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: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be removed before operating the vehicle over the road.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

All vehicles

1. Move and tilt the front seats to their highest and rearmost position.

2. Turn all vehicle accessories OFF.

3. Turn the ignition switch to OFF.

4. At the central junction box (CJB), located below the LH side of the instrument panel, remove the cover and the restraints control module (RCM) fuse F2.23 (10A) from the CJB.

5. Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continously (no flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continously, remove the correct RCM fuse before proceding.

6. Turn the ignition OFF

7. 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 (if equiped) are located at or near the base of the B-pillars.

To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minuite. Be sure to disconnect auxilary batteries and power supplies (if equipped).

Disconnect the battery ground cable and wait at least one minuite.





8. Through the steering wheel access door, disconnect the driver air bag module electrical connector and attach the restraint system diagnostic tool.





9. Open the glove box to its fullest extent by pushing in on the tabs and release the glove compartment.





10. Through the glove box opening, remove the passenger air bag module retaining bolts.





11. Separate the passenger air bag module and trim cover from the Instrument Panel (I/P).
1 Pull the left hand comer of the trim cover away from the I/P.
2 From left to right, slide across the seam between the trim cover and I/P, releasing the trim cover retaining clips.
3 Pull the passenger air bag module and trim cover away from the I/P, but do not remove it.





12. Remove the passenger air bag module and trim cover.
1 Disconnect the passenger air bag module electrical connector.
2 Remove the wire harness pin-type retainer from the passenger air bag module.
3 Remove the passenger air bag module.





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

Vehicles without side air bags

14. 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 connector, a low resistance fault will be generated by the RCM.





Vehicles with side air bags
15. From under the passenger seat, disconnect the side air bag module electrical connector.





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





Vehicles with side air bags
17. From under the driver seat, disconnect the side air bag module electrical connector.





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

19. Install the RCM Fuse F2.23 (10A) to the CJB.

20. Connect the battery ground cable.
