Question 1

How to Safely Arm and Disarm an Air Bag in the Supplemental Restraint System (SRS) on Lincoln MKZ?

Accepted Answer

Wear protective eye gear when deactivating the Supplemental Restraint System because the deployment of safety features will result in fatal injuries and protect against accidental safety element release through memory saver devices. It is unsafe to probe electrical connectors on air bag modules together with safety belt pretensioners. The Restraints Control Module (RCM) shows an air bag warning indicator when the correct fuse 25 (7.5A) is taken out and the ignition key is set to ON position. All accessories on the vehicle should be turned to OFF position followed by applying the OFF setting to the ignition before removing the RCM fuse from the Smart Junction Box (SJB). After pulling out the fuse users should turn the ignition ON to confirm the air bag warning indicator stays on for more than 30 seconds. Continue by removing the fuse which contains the correct RCM. The battery ground cable needs disconnecting and at least one minute of waiting time for the back up power to drain before proceeding. A 3-mm Allen wrench can be used to unlock the two locking pins of the driver air bag module allowing users to release the electrical connectors without damaging the locking buttons. The passenger air bag module removal starts with the disassembly of two bolts followed by unclipping the deployment door retention clips. One should repeat these same steps while disconnecting electrical connectors from the passenger seat side air bag module and both side air curtain modules accurately. The last step includes reconnecting the battery ground cable together with installing the RCM fuse. The process to activate the SRS begins with RCM fuse removal followed by a one-minute battery ground cable disconnect and subsequent reconnection of every air bag module electrical connector when the locking buttons should remain in their released position. Place the passenger air bag module correctly while securing it with bolts before returning the trim panels to their original position. Finish the process by joining driver air bag electrical connectors and then position the module correctly to the steering wheel before installing the RCM fuse. A battery connection procedure must follow and you should verify the SRS using the air bag warning indicator for proper functionality. A scanning tool must be used to clear continuous DTCs from the RCM and Occupant Classification System Module (OCSM) before diagnosing and repairing any detected faults.

Question 2

How Should You Safely Service and Repair a Side Air Bag Curtain Module on Lincoln MKZ?

Accepted Answer

All personnel should use eye protection during side air curtain module servicing to protect against severe injuries. You should handle the live safety canopy or side air curtain module with its module and tear seam directed away from your body to stay safe in case deployment occurs accidentally. The inspection of damaged rooflines should precede safety canopy and side air curtain module installation because repair must restore the sheet metal to its original state while its integrity must be preserved and new fasteners should replace old damaged ones. Install the word air bag on the headliner at each B-pillar trim panel because installing an incorrect headliner might result in unsafe safety canopy or side air curtain module deployment during crashes which increases crash-related injuries. The replacement process requires a new headliner and all A-, B-, and C-pillar upper trim panels together with their attaching hardware as well as the removal of damaged components after the safety canopy or side air curtain module deployment. A thorough examination of the safety canopy and side air curtain module must occur before installation but replacement of the module must be done if damage exists. Any attempt to fasten or tie strap around parts of the safety canopy or side air curtain module will prevent proper deployment so these methods should be avoided completely. Keep away from testing the electrical connectors because probing them might cause the modules to deploy unintentionally. A warning indicator will illuminate from the restraints control module (RCM) when a technician removes its fuse with the ignition switch activated since this condition is normal without any fault. A vehicle should only leave the garage once repair technicians confirm the SRS operates properly without errors. New components need installation for all repairs but if the issue remains the original part needs reinstallation followed by diagnostic procedure repeating. The first step to remove the side air curtain module consists of removing the headliner then deactivating the SRS system through power removal followed by disconnecting the electrical connector and releasing the wiring retainer before removing required bolts while documenting the rear bracket hook's original position with the center guide hook retainer. During the installation sequence inspect both the roofline and module design so each bolt hole will correctly match. First depower the SRS system then reinstall the headliner before refitting all bolts to 7 Nm (62 lb-in). Complete the process by activating the SRS system.
