  Q: How Should the Air Bag Sensor in the Second Row, C-Pillar, Be Serviced to Ensure Safety and Proper Functionality on Lincoln LS?

  A:

  People servicing the side impact sensor in the C-pillar of the second row need to use safety glasses for minimization of personal risks during supplemental restraint system (SRS) air bag repairs. The vehicle sensor orientation needs to be precise before system operation begins while inspecting the sensor mounting bracket along with the damaged wiring pigtail for any signs of misalignment. Replace the sensor during this process as well as the entire SRS system components if necessary even if air bags did not trigger. The use of memory saver devices should be avoided because they create risks of personal injury to repairers. When the RCM fuse comes out while the ignition switch is ON the air bag warning lamp will activate and this normal condition signifies no SRS fault exists. Vehicle return to the customer requires that the SRS system operates without faults. The repair process needs to install new components but additional diagnostic testing should occur after reinstallation of original elements. To start the process depower the system next remove the rear seat bolster from the affected side along with disconnecting the electrical connector of the side impact sensor before removing its two securing bolts. The installation of the new sensor requires users to position its locator tab into the C-pillar sheet metal slot before assembly. The correct operation of the system depends on tightening retaining bolts to 12 Nm (9 lb-ft). You should reconnect the mathematical connector to the side impact sensor while also reinstalling the rear seat bolster before repowering the system then checking the active restraint system for proper functioning.

  Q: What Precautions Should Be Taken When Servicing the Front Air Bag Sensor on Lincoln LS?

  A:

  Safety glasses must be worn during front impact severity sensor service to protect users against air bag activation accidents. The vehicle sensor needs proper orientation to work according to specifications. Before using the sensor or any supplemental restraint system components following a crash you must inspect and either replace or reposition both the sensor and wiring components even without air bag deployment. The use of memory saver devices should be avoided because it produces safety hazards. The air bag warning lamp will turn on when you remove the RCM fuse because it is a normal condition that does not point to any system fault. A complete check of the SRS operational readiness should occur before the vehicle gets returned to the customer. The diagnostic process requires new part installation as the repair method with further inspection if symptoms return to the point of restarting the diagnostic steps with original components. To start the repair procedure users should downpower the electrical system followed by disconnecting the front impact sensor connector before removing the retaining bolt to extract the sensor. Start by cleaning both the mounting bracket along with the sensor mating surfaces. Place the tags on the sensor to match the bracket openings before inserting the sensor into place. A correct system operation requires the retaining bolt to be tightened up to 12 Nm (9 lb-ft). Replug the wire connector before restarting power to the system.
