  Q: How to Service and Repair the Clock Spring Assembly to Ensure the Supplemental Restraint System (SRS) is Operational on Lincoln Mark LT?

  A: The safety of returning vehicles to customers requires complete operation of the supplemental restraint system along with no errors detected in the SRS before performing Clock Spring service or repair work. During ignition the warning indicator should activate while the restraints control module (RCM) fuse is disconnected from its power source although no fault exists. The repair procedure includes new part installation but replacing the original part should be considered if problems continue and diagnostics need to be restarted. Start the SRS depowering process after verifying that all road wheels face forward. You need to uninstall the driver Air Bag module combined with the steering wheel as well as the lower steering column shroud screw and the two upper steering column shroud screws along with the upper shroud. Two strips of masking tape must be applied to the Clock Spring when reuse is planned to stop accidental rotation. The installation starts with removing the multi-function switch screw and the switch component following the steps of releasing the retaining tab before sliding it away. Remove the Clock Spring after disconnecting electrical connectors and removing its three clips. Check the mounting bracket for any damage and perform a replacement if needed while tightening it to 6 Nm (53 lb-in). Before assembly always position the Clock Spring at its installation center to prevent premature failure from occurring. Process the outer housing while keeping it static and turn the rotor counterclockwise until it meets resistance then continue turning clockwise for three rotations until the center point is reached. Use tape to protect the Clock Spring from unintended rotation. Place the flat sides of the Clock Spring opposite the steering column then insert it onto the column shaft. New Clock Springs require the removal of the retaining pin but reused parts need the tape to be removed. Hook up the electrical connectors by aligning them before choosing their complete seating position. Begin by installing both the multi-function switch together with its screw and continue with attaching screws for upper/lower steering column shrouds. Finish the installation process by adding the steering wheel along with the driver air bag module and then enable SRS power.
