Pinpoint Test F: The Driver Power Seat Does Not Move Horizontally/Vertically (Without Power Recliner): Testing

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
  1. F1 CHECK HORIZONTAL DIRECTION MOTOR FOR CORRECT OPERATION 
    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: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
    NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
    NOTE: 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.
