  Q: What Precautions Should Be Taken When Servicing the Clock Spring to Minimize Injury Risk and Ensure Proper Functionality on Lincoln Mark LT?

  A:

  Both safety glasses and the absence of memory saver devices are essential during Clock Spring assembly maintenance to prevent accidental Air Bag deployment injuries and protect vehicle safety. The vehicle should return to customers only when the SRS operates correctly with no identified faults in its operation. The RCM fuse removal will activate the air bag warning lamp while the ignition switch remains ON but this is a normal condition that signifies no SRS defect is present. The repair process includes installing a fresh part until further problems occur where the technician will need to reinstall the original component before performing diagnosis again. Initiate systemic depowering procedures before realigning the road wheels to a forward position. The technician must first remove the driver air bag module coupled with the steering wheel and lower steering column shroud screw and upper steering column shroud screws to free the upper shroud. The Clock Spring can be reinstalled after users apply two pieces of masking tape to stop rotational movement while removing it. The next step involves uninstalling the multi-function switch screw and the switch from its position followed by sliding it out with the retaining tab release. You should then disconnect the Clock Spring electrical connectors before releasing the three clips for Clock Spring removal. Check the mounting bracket for damage and substitute it when required then perform final tightening up to 6 Nm (53 lb-in). Installation should have proper component centralization to prevent early malfunction while maintaining road wheel alignment. Secure the Clock Spring housing nonetheless while gradually turning the rotor backward until pushback occurs before following with a clockwise rotation of about three full turns to achieve positioning at the center point. To stop accidental rotation apply adhesive tape. Install the steering column by placing the Clock Spring flats properly then slide it onto the column while securing both electrical connectors firmly. Mount the multi-function switch and its screw and install both upper and lower steering column shrouds with their screws. The system requires the driver air bag module and steering wheel reinstallation prior to restarting the system power.
