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.
- The belt and buckle assembly pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a belt and buckle assembly pretensioner.
- 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 belt and buckle assembly pretensioner is a pyrotechnic device. Never probe the connectors on the belt and buckle assembly pretensioners. Doing so could result in belt and buckle assembly pretensioner or air bag deployment and could result in personal injury.
- Air bag modules with discolored or damaged trim covers must be installed new, not repainted.
- 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:
- There is no restraint system diagnostic tool for the safety belt buckle pretensioners. If the ignition switch is turned to the RUN or START position with the safety belt buckle pretensioner electrical connector(s) disconnected, the DTC for an open circuit will be activated.
- 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.

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 front impact severity sensor is located behind the grille.

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.
