  Q: How to service and repair the Air Bag Sensor located in the first row, B-pillar on Lincoln Aviator?

  A:

  Proper system operation of the side impact sensor in the first row, B-pillar requires correct vehicle sensor orientation during service and repair procedures. You must examine the sensor mounting bracket and wiring pigtail after any collision with an Air Bag supplemental restraint system (SRS) vehicle to check for deformation. Replace and correctly position the damaged sensor or SRS components whether there was air bag deployment. Workers must always use safety glasses when operating on SRS vehicles and handling air bag modules because it reduces risks of accidental deployment injuries and it is also important to avoid using memory saver devices because they decrease personal injury potential. The SRS needs complete functionality without defects for vehicle return to customers. Replacements should be made with new parts yet reinstalling the original component is necessary if the newly installed part fails to address the problem. You should then perform another diagnostic procedure. Start by disabling the system power before proceeding to remove the B-pillar trim panel along with the components according to their installation order. Before attaching the new side impact sensor you must ensure the bolt together with washer and clip are properly installed followed by aligning the locator pegs with B-pillar sheet metal openings. It is essential to adhere to correct tightening protocols when securing the air bag side impact sensor retaining bolt for proper system operation because the installation requires the opposite sequence of removal steps followed by reactivating the power system.

  Q: Is the Front Air Bag Sensor Critical for SRS Operation, and How Should It Be Installed and Inspected on Lincoln Aviator?

  A:

  The front impact severity sensor functions as a vital element for air bag supplemental restraint system operation so the installer should keep it correctly oriented throughout assembly. Check the sensor mounting bracket and wiring pigtail for damage following any collision and replace them and restore their position together with all impaired SRS components even if air bags do not deploy. Safety glasses should always be worn at all times while performing SRS work activities to protect against accidental deployment injuries in addition to never using memory saver devices. When the RCM fuse is removed on a vehicle with ignition ON the air bag warning lamp should turn on yet this normal condition represents no actual defect. Test the SRS system completely to check for faults and restore the vehicle to its customer only when it functions properly. The repair should start with installing a new part while repeating the diagnostic procedure after reinstalling the original part when issues remain. The first step involves performing a system depowering procedure and removing the electrical connector of the front impact severity sensor. When installing new sensor mounting bolts users need to secure them to a torque setting of 12 Nm (9 lb-ft). When installing the front impact severity sensor the removing step requires positioning the sensor mounting bracket's locator tab into the lower radiator support sheet metal opening. The system operates correctly only when retaining bolt torque meets specifications while removing all debris from the lower radiator support and sensor bracket mating surfaces. Finally, repower the system.
