2009 Lincoln MKS Air Bag Sensor Parts Q&A

• Q: How to service the Air Bag Sensor in the front door for side impact on 2009 Lincoln MKS?

  A: Service of the front door side impact sensor starts with verifying no crash involvement exists but when present examine the RCM and impact sensor mounting locations for any damage prior to restoring them to their pre-production condition. The installation of a new RCM and sensors is mandatory before any crash to secure vehicle safety in a collision. It is essential to use the correct Supplemental Restraint System (SRS) part through direct Ford Catalog Advantage™ verification or equivalent sources because using incorrect parts has the risk of setting off diagnostic trouble codes (DTCs). The air bag warning indicator will turn on following removal of the correct RCM fuse under ON ignition conditions and before returning the customer's vehicle the SRS requirements must be met without defective statuses. The SRS depowering process must be completed and then move to unclip the front door trim panel before disconnecting the side impact sensor electrical connector. Take the two screws off which secure the side impact sensor. The side impact sensor bolts need only be tightened enough for proper sensor bracket installation to prevent insert nut stripping. Alteration or replacement of a damaged insert nut should consider using a new replacement part. To finish the process install the new sensor while reversing all removal steps before enabling power to the SRS system.
