Control Module

A new Restraints Control Module (RCM) installation requires programming according to the specific vehicle configuration. Check that all SRS components exist along with a battery connection before continuing. The Data Link Connector (DLC) needs a scan tool connection while the key goes to the RUN position. The RCM setting process requires following the scan tool producer instructions to pick "Air Bag Configuration 12" for Continental models with side air bags or "Air Bag Configuration 13" for Continental cars without side air bags. The system should be configured and then a key turn to OFF position must follow before system proofing begins. The Restraint System Diagnostic Tool exists only for vehicle restraint system maintenance yet it should always be detached from cars before riding on roads to prevent safety complications. After proving the system shows Lamp Fault Codes (LFCs) refer to the Diagnostic Trouble Code (DTC) Priority Table.

Using protective safety glasses is mandatory for replacing or removing the side impact sensor due to the potential air bag deployment hazard. The correct functioning of sensor orientation requires assessment of the sensor bracket and wiring pigtail for collision-related deformation after a crash. Replace all affected parts irrespective of air bag discharge. Start the supplemental restraint system (SRS) proof by placing the ignition switch on from OFF position and watching the air bag indicator turns on for six seconds before going off. Continue with the repairs only after resolving all SRS system errors that appear through the indicator or prevent it from turning off. First detach the central junction box panel under the left side of the instrument panel by removing its cover. Then remove fuse 9 which has a rating of 10 A from the restraints control module. Push the front seats to maximum height and forward position followed by disconnecting the battery ground cable while waiting one minute for power depletion. Reach the side impact sensor underneath the front seat carpet by removing the wire harness pin-type retainer and the two retaining bolts to position the sensor with bracket out of position. Context: Regularly inspect the side impact sensor and remove both components, the sensor as well as its bracket. You should begin installation by maintaining battery negative cable disconnect and proceed to connect the side impact sensor before correctly positioning it and securing it with two retaining bolts and reinserting the wire harness pin-type retainer. Reinstall the restraints control module fuse 9 (10 A) after turning the ignition switch from OFF to ON along with covering the junction box. Reestablish ground battery cable connection after checking that both the vehicle seat area and air bag equipment paths are free from obstacles. The SRS requires another proof-out process by moving both front seats into the rear position while checking the air bag indicator shows proper operation after switching the ignition key through ON to OFF states with a 10-second pause. Test and repair faults when the detection system finds any issues.

Correct orientation along with safety measures guide the replacement work on the air bag control module and its restraints control module (RCM) for bench and bucket seats to maintain the proper function of the air bag supplemental restraint system (SRS). Any center tunnel area collision requiring inspection of RCM mounting and bracket for deformation will lead to a new RCM even without air bag deployment. Always maintain safety through wearing protective eyewear when dealing with air bag components because accidental deployments may result in injuries. It is necessary to drain the back up power supply when servicing SRS components by disconnecting the battery ground cable (14301) while waiting at least one minute and also removing auxiliary batteries and power supplies. The bench seat requires removal of the driver side bench seat followed by disconnection of the RCM's two electrical connector locking clips which allows access to two electrical connectors while the three RCM bracket retaining bolts become accessible through carpet repositioning. The RCM removal begins by disconnecting the battery ground cable followed by floor console removal when present as well as the air flow duct, its mounting bracket and finally disengaging the electrical connector locking clip before disconnecting the electrical connectors. The installation sequence starts with reversing all removal operations while making sure the orientation of the RCM is correct and setting the RCM bracket retaining bolts to the specified torque for appropriate system operation. Always remove the restraint system diagnostic tool before driving since its service use only but never leave it mounted on the vehicle as it leads to hazard risks and safety standards breaches. Verify that the air bag system operates correctly.

All SRS components must be installed and the battery must be connected.

Always wear safety glasses to reduce the risk of injury from accidental air bag deployment.

Vehicle sensor orientation is critical for correct system operation; inspect the sensor mounting bracket and wiring pigtail for deformation after a collision.
