2009 Lincoln Town Car Air Bag Sensor Parts Questions & Experts Answers

• Q: How Should the Front Air Bag Sensor Be Serviced to Ensure Safety and Proper Functionality on 2009 Lincoln Town Car?

  A: Check for crash damage to the vehicle before servicing the front impact severity sensor because any detected damage must be inspected in the restraints control module (RCM) and impact sensor mounts which must return to original production condition if needed. A new RCM system and sensors need installation as a standard practice even if air bags were not deployed to ensure condition safety during vehicle crashes. The RCM fuse indicator turns on when the proper fuse is removed under ON ignition conditions showing the Supplemental Restraint System must be entirely functional along with no defects before releasing the vehicle. The front impact severity sensors exist in pairs which are positioned at each side of the hood latch on the radiator core support. Begin by depowering the SRS. The maintenance sequence starts with removing pin-type retainers and the radiator opening cover assembly while also disconnecting the bolt and horn and bracket assembly from the right-hand side. Perform the following steps when installing the front impact severity sensor: first disconnect the horn electrical connector and then detach the sensor bolts followed by securing the new sensor with torque to 12 Nm (106 lb-in). After disconnecting the electric cable from the front impact severity sensor, workers must reverse the uninstallation steps to finish the task. Finally, repower the SRS.
