SAS CONTROL MODULE REMOVAL/INSTALLATION

id081000801400

Removal

Warning

• Always wear safety glasses when repairing an air bag equipped vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental operation (deployment).

• After operation (deployment), the air bag surface can contain deposits of sodium hydroxide, a product of the gas generating combustion that is irritating to the skin. Wash your hands with soap and water afterward.

• Never probe the connectors on the air bag module with a tester. If it is probed directly, the deployment of the air bag could result in personal injury.

• The direction of the SAS control module installation is critical for proper air bag system operation (deployment). If a vehicle equipped with an air bag system has been involved in a collision in which the center tunnel area has been damaged, inspect the mounting and bracket for deformation. If damaged, the SAS control module must be replaced whether or not the air bags have operated (deployed). In addition, make sure the area of the SAS control module is restored to its original condition.

• The air bag sensor is important for proper air bag system operation. If a vehicle equipped with an air bag is involved in a collision, inspect the sensor mounting bracket and wiring harness connectors for deformation. Replace and properly position the sensor or any other damaged structural components whether or not the air bag has operated (deployed).

• To avoid accidental deployment of the air bag and possible personal injury, always deplete the back-up power supply before repairing or replacing any front or side air bag structural component, and before servicing, replacing, adjusting, or causing impact to components near the air bag sensors, such as doors, dashboard, console, door latches, strikers, seats and bonnet latches.

• Before servicing, refer to this workshop manual to determine the location of the crash zone sensor.

• The side air bag sensors are located at or near the base of the B-pillar.

• To deplete the backup power supply, disconnect the battery negative cable and wait for 1 min or more. Be sure to disconnect auxiliary batteries and power supplies (if equipped).

Caution

• Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage can result.

Note

• Replace only with new parts. If the new part does not correct the malfunction, install the original part and perform the diagnostic procedure again.

All The Vehicles

1. Disconnect the negative battery cable and wait 1 min or more.

Warning

• The SST (diagnostic simulator) is for air bag system servicing only. Before using the vehicle, it must be removed. Failure to remove it could result in personal injury and loss of vehicle safety standards.

Note

• If a seat equipped with a seat mounted side air bag or a pre-tensioner front buckle (if equipped) is being serviced, the air bag system must be deactivated.

• The SST (diagnostic simulator) must be installed under the seats in the side air bag and pre-tensioner front buckle (if equipped) to floor connectors.

• Diagnostics or repairs are not to be performed on a side air bag system or a pre-tensioner front buckle (if equipped) with the seats in the vehicle. Prior to attempting to diagnose/repair the side air bag system or a pre-tensioner (if equipped) system the seats must be removed from the vehicle and the SST (diagnostic simulator) must be installed in the side air bag and the pre-tensioner front buckle (if equipped) connectors at the floor connectors. Remove the SST (diagnostic simulator) before operating the vehicle on the road.

• Diagnostics may be performed on seat systems other than the side air bag or pre-tensioner front buckle (if equipped) (lumbar, climate control, heat, 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 and pre-tensioner front buckle to floor connectors.

• After diagnosing/repairing the seat system, always remove the SST (diagnostic simulator) before operating the vehicle on the road.

2. Disconnect the driver-side air bag module connector.

3. Attach the SST (diagnostic simulator) to the clock spring connector at the top of the steering column.

4. Fully open the glove compartment.
