Air Bag Control Module: Service and Repair
RESTRAINTS CONTROL MODULE (RCM)Removal
WARNING: The restraints control module (RCM) orientation is critical for proper air bag supplemental restraint system (SRS) operation. If a vehicle equipped with an SRS 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 RCM must be replaced whether or not the air bags have deployed. In addition, make sure the area of the RCM mounting is restored to its original condition. Failure to follow these instructions may result in personal injury.
WARNING: 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. Failure to follow these instructions may result in personal injury.
CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage can result.
NOTE: Repair is made by installing a new part only If the new part does not correct the condition, install the original part and perform the diagnostic procedure again.
WARNING: The restraint system diagnostic tool is for restraint system repair only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
NOTE: Diagnostics or repairs are not to be performed on a side air bag system and/or a safety belt pretensioner (if equipped) system with the seats in the vehicle. Prior to attempting to diagnose/repair the side air bag system and/or a safety belt pretensioner (if equipped) system the seats must be removed from the vehicle and the restraint system diagnostic tools must be installed in the side air bag and the safety belt pretensioner (if equipped) connectors at the 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 or the safety belt pretensioner (if equipped) 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 and safety belt pretensioner to floor connectors.
NOTE: After diagnosing/repairing a seat system the restraint system diagnostic tools must be removed before operating the vehicle over the road.
1. Depower the system. See SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING.
2. Position the carpet back at the right-hand side of the center tunnel area under the instrument panel.
3. Remove the right-hand side restraint control module (RCM) retaining bolts.
4. Position the carpet back at the left-hand side of the center tunnel area under the instrument panel.
5. Remove the RCM.
1. Slide and disengage the two RCM electrical connector locking clips.
2. Push down to pivot the RCM electrical connector tabs and pull out to disconnect.
3. Remove the retaining bolt.
