Deactivation and Reactivation Procedures

Deactivation and Reactivation Procedures

Deactivation Procedure

WARNING: If the supplemental restraint system (SRS) is being serviced, the system must be deactivated and restraint system diagnostic tools must be installed.

WARNING: The air bag restraint system diagnostic tools must be removed and the air bag modules reconnected when the system is reactivated to avoid non-deployment in a collision, resulting in possible personal injury.

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 pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner.

Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.

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.

WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.

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

1. Disconnect the negative battery cable.
2. Wait at least one minute for the backup power supply in the restraints control module (RCM) to deplete its stored energy.
3. Remove the driver air bag module.
4. Attach restraint system diagnostic tool 418-F088 to the clockspring side of the driver air bag module electrical connector.
5. Disconnect the passenger air bag module.
6. Attach a restraint system diagnostic tool 418-F088 to the vehicle harness side of the passenger air bag module electrical connector.

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

7. Reconnect the negative battery cable.

Reactivation Procedure

WARNING: The air bag restraint system diagnostic tools must be removed and the air bag modules reconnected when the system is reactivated to avoid non-deployment in a collision, resulting in possible personal injury.

8. Disconnect the negative battery cable.
9. Wait at least one minute for the backup power supply in the restraints control module (RCM) to deplete its stored energy.
10. Connect the driver safety belt buckle pretensioner electrical connector as required.
11. Connect the passenger safety belt buckle pretensioner electrical connector as required.
12. Remove the restraint system diagnostic tool from the passenger air bag module electrical connector.
13. Connect the passenger air bag module electrical connector.
14. Remove the restraint system diagnostic tool from the driver air bag module electrical connector.
15. Install the driver air bag module.
16. Reconnect the negative battery cable.
17. Using the scan tool, clear all RCM DTCs.
18. Prove out the system.
