WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
  1. A1 CHECK CIRCUIT 566 (DG) FOR VOLTAGE 
    WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
    NOTE:
    1. If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the SRS must be depowered.  Refer to DEPOWERING PROCEDURE .
    2. The air bag warning lamp illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
    3. The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
    4. The memory seat track motor electrical connectors will connect to a seat track without the memory option. When installing a new seat track, make sure the correct memory or non-memory seat track is being installed.
    • Key in OFF position.
      • WARNING: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the battery ground cable is connected.
    • For vehicles equipped with seat side air bags, carry out the following:
      • Depower the SRS. Refer to DEPOWERING PROCEDURE .
      • Disconnect driver seat side air bag C3226.
      • Connect restraint system diagnostic tool 418-133 to driver seat side air bag C3226.
      • Connect the battery ground cable.
    • Disconnect: Driver Seat Control Switch C369.
    • Measure the voltage between driver seat control switch C369-5, circuit 566 (DG), harness side and ground.
