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.
- 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.
- Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment.
- 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 safety canopy module. Doing so can result in safety canopy deployment, which can result in personal injury.
- 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.
- 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.
- 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 air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the air bag system must be deactivated.
- Restraint system diagnostic tools MUST be installed under the seats in the seat side air bag (if equipped) and safety belt pretensioner (if equipped) to floor connectors.
- Diagnostics or repairs are not to be performed on a seat equipped with a seat side air bag with the seat in the vehicle. Prior to attempting to diagnose or repair a seat concern when equipped with a seat side air bag, the seat must be removed from the vehicle and the restraint system diagnostic tools must be installed in the seat side air bag electrical connectors. The restraint system diagnostic tools must be removed prior to operating the vehicle over the road.
- 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.
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 or RCM, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
The front impact severity sensor is located under the hood latch bracket.
The first row side impact sensors (if equipped) are located under the seat, beneath the carpet.
The second row side impact sensors (if equipped) are located at or near the base of the C-pillar.
To deplete the backup power supply energy, disconnect the battery and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
Disconnect the battery and wait at least one minute.
2. Open the steering wheel access door.
3. Release the tab and slide the connector off.
4. Disconnect the driver air bag module.
1 Push the driver air bag module electrical connector together.
2 Push down, pivoting the electrical connector and release the electrical connector retainer.
3 Pull out, disconnecting the vehicle harness end of the connector from the component end.
5. Attach the restraint system diagnostic tool to the clockspring electrical connector at the top of the steering column.
6. Push in on the 2 glove compartment door tabs and position the glove compartment downward.
7. Through the glove compartment opening, 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 module electrical connector.
Vehicles without safety canopies and seat side air bags
9. CAUTION: Do not deactivate the safety canopy module circuit by removing the safety canopy bridge resistor from the safety canopy electrical connector.
If the safety canopy 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 safety canopy electrical connector, a low resistance fault will be generated by the RCM.
10. 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 electrical connector, a low resistance fault will be generated by the RCM.
