Deactivation and Reactivation Procedures
Restraint System Diagnostic Tool WarningWARNING: This 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.
Deactivation Procedures
There are two deactivation procedures.
- One procedure requires removal of the front seats. This procedure will be used when diagnosing side air bag concerns, and also when repairing any in-seat component in vehicles equipped with side air bags.
- The other procedure does not require front seat removal. This procedure will be used when diagnosing a concern not related to the supplemental restraint system (SRS).
Deactivation Procedure - Seats Removed
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 vehicle workshop manual to determine location of the front air bag sensors.
The side air bag sensors are located at or near the base of the B-pillar.
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).
WARNING: The air bag 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 system is being serviced, the air bag system must be deactivated using the appropriate deactivation procedure.
NOTE: Restraint system diagnostic tools MUST be installed under the seats in the side air bag floor connectors.
NOTE: Diagnostics or repairs are not to be performed on a side air bag system with the seats in the vehicle. Prior to attempting to diagnose/repair the side air bag system, the seats must be removed from the vehicle and the restraint system diagnostic tools must be installed in the side air bag floor connectors. The restraint system diagnostic tools must be removed prior to operating the vehicle over the road.
NOTE: Diagnostics may be performed on seat systems other than the side air bag system (lumbar, climate controlled, heated, power seat track) with the seat installed in the vehicle as long as the restraint system diagnostic tools are installed under the seats in the side air bag floor connectors.
NOTE: After diagnosing/repairing a seat system, the restraint system diagnostic tools must be removed before operating the vehicle over the road.
