• Q: How to Service and Repair the Clock Spring Assembly on 2008 Mercury Mariner?

  A: Service and repair of the Clock Spring assembly requires depowering the SRS system first to avoid dangerous deployments while also refraining from using memory saver devices. The RCM fuse removal activates the air bag warning indicator during ignition ON operations but this condition does not signal an SRS defect. A full operational check for SRS system faults must be performed to ensure proper vehicle return to customers. The diagnostic process should start with new part installation followed by reversing to the original part and repeating diagnosis when the outcome remains unchanged. To protect the Clock Spring perform the following steps: Lower the steering wheel using the provided handle while securing it in place and then straighten the road wheels to avoid Clock Spring damage. Start by taking out the assembly of the 2-piece upper steering column shroud followed by removing the 3 lower steering column shroud screws before you can release the tilt column locking lever to take off the lower shroud. Remove the Clock Spring electrical connector before taking out its two retaining screws. New Clock Springs require the anti-rotation key to stay in place until installing the steering wheel because removing it early requires clockwise rotor rotation until resistance is felt and another 4 clockwise turns for correct centering. To ensure proper centering check that the rotor window sits at the 4 o'clock marks while the yellow indicator shows and the inner and outer rotor arrow points at the 6 o'clock mark with inner rotor wiring and connector located at the 12 o'clock position. Straighten the road wheels before inserting the steering wheel and remove the anti-rotation key when replacing the Clock Spring. Reinstallation of the driver air bag module should be followed by a power-up of the SRS system.
