  Q: How is the Clock Spring Serviced and Repaired in an Air Bag Supplemental Restraint System (SRS) on Mercury Mountaineer?

  A:

  Work on an Air Bag supplemental restraint system (SRS) vehicle requires safety glasses to reduce the chances of accidental deployment injuries because servicing the Clock Spring assembly. Additionally it is important to avoid memory saver devices during this process. When the RCM fuse is removed while the ignition switch is ON the air bag warning lamp will activate in a normal operation although it does not suggest SRS malfunction. A full operational check of the SRS should be performed to verify no faults exist before returning the vehicle to customers. To solve persistent issues a new part must be installed before repeating the diagnosis procedure by putting back the original component. Start by switching off the power supply to the system followed by checking that road wheels are oriented forward. First lock the tilt handle downward while tilting the Steering Wheel before taking off the driver air bag module along with the steering wheel and lower steering column opening cover and lower steering column shroud. First detach the Clock Spring electrical connector followed by removal of the Steering Angle Sensor before you take out the Clock Spring. Install the new Clock Spring by fastening it with two screws followed by attaching the steering angle sensor and resecuring the electrical connector. Put together the upper and lower steering column shrouds as well as the lower steering column opening cover. Steering wheel attachment is required before removing the Clock Spring sealing key when installing a new Clock Spring. To preserve Clock Spring longevity normalize its position; simultaneously restrain the outer casing while rotating the rotor backward until resistance occurs follow with forward rotation that completes 2.5 turns until wiring and connector face the twelve o'clock mark. The technician needs to maintain the rotor position at any time before returning to install the steering wheel. Also reinforce the centralizing procedure before continuing if the technician leaves the vehicle unattended. You should finish the installation by inserting the driver air bag component before switching on the power.

  Q: What Precautions Should Be Taken When Servicing the Clock Spring on Mercury Mountaineer?

  A:

  You should always wear safety glasses while servicing the Air Bag sliding contact because they reduce the potential of accidental deployment injuries. A technician should handle live air bag modules by pointing their air bag and trim cover toward different directions from their body with strict avoidance of placing modules on any surface with the trim cover touching down. Wash your hands with soap and water to clean off any irritative sodium hydroxide residue which may form after deployment. Probing the connectors of an air bag module must be avoided to stop accidental deployment from occurring. It is safer to replace air bag modules with new trim covers instead of attempting to repainting the damaged ones. Check the SRS supplemental restraint system sensor orientation while inspecting the mounting bracket and wiring pigtail to replace any deformed parts which occur during collisions even if air bag deployment did not happen. Diminish the power back up reserves by pulling the ground Battery Cable and waiting for at least one minute while also separating auxiliary batteries from the system if available. The procedures to remove the air bag sliding contact start by disconnecting the battery ground cable followed by air bag module and Steering Wheel removal while keeping the wheels aligned forward. Begin by covering the air bag sliding contact with masking tape to stop its rotation. Then detach the lower steering column opening finish panel by removing retaining screws and releasing all clips. The following step involves removing the lower steering column opening finish panel reinforcement and loosening the steering column to instrument panel retaining bolts for removal of the upper steering column shroud. You can remove the Ignition Switch lock cylinder when it is positioned at the RUN setting by pushing up on the release tab on the cylinder. The technician needs to take out two components: the Passive Anti-Theft System (PATS) Transmitter and the key-in-ignition warning indicator switch. The two air bag sliding contact wire connectors need to be disconnected followed by removing the wire harness from its holders. The lower air bag sliding contact retaining clip needs release before proceeding to extract the contact by unfastening more clips. To put back the air bag system use the reverse steps of the removal process while going through air bag system validation. Service personnel should remove the restraint system diagnostic tool from vehicles before road use since this tool exists for service purposes yet violates safety standards and can cause injuries.
