• Q: How Should the Side Impact Air Bag Sensor Be Serviced to Ensure Safety and Proper Function on 2007 Mercury Grand Marquis?

  A: Safety glasses should be used for side impact sensor servicing to protect against possible injuries from accidental air bags while abstaining from memory saver devices. The sensor orientation in vehicles requires immediate examination due to its vital role in operation; any vehicles with supplemental restraint systems (SRS) from collisions need a sensor mounting bracket evaluation along with wiring pigtail checks for deformities. Replace and precisely position the sensor or seek replacement of damaged SRS components regardless of air bag initiation. A warning lampillumination occurs when the restraints control module (RCM) fuse disconnects with the ignition switch ON though this behavior should not indicate any malfunction. Vehicle release requires complete functionality of the SRS without faults before giving the car back to the customer. After new part installation the customer should test once again if the issue returns to repeat initial diagnostic steps. The procedure starts with system depowering followed by removal of front and rear door scuff plates and then unclipping front and rear door B-pillar weather stripping before extracting the lower B-pillar trim panel. Disconnect the electrical connector and remove two bolts from the side impact sensor with bracket according to the specified order. After placing the air bag side impact sensor with bracket restore the retaining bolts to 12 Nm (9 lb-ft) torque setting and follow the bolt installation order. The correct order for installing the side impact sensor with bracket includes using bolts to attach it followed by electrical connector connection and then inserting the lower B-pillar trim panel for alignment before weather stripping reattachment whereas the system repowering requires completing these steps.
