Pinpoint Test K: The Power Seat Does Not Move Horizontally/Recline - Fusion/MILAN, Passenger

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: If a seat equipped with a seat mounted side air bag is being serviced, the Supplemental Restraint System (SRS) must be depowered. Refer to SUPPLEMENTAL RESTRAINT SYSTEM -- FUSION, MILAN & MKZ article.
NOTE: 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 an SRS fault.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  1. K1 CHECK THE HORIZONTAL MOTOR FOR CORRECT OPERATION 
    • Operate the passenger power seat forward and rearward.
    • Does the seat move horizontally? 
    1. Yes  : GO to  K5.
    2. No  : GO to K2  .
  2. K2 CHECK VOLTAGE TO THE PASSENGER SEAT HORIZONTAL MOTOR 
    • Ignition OFF.
    • Depower the SRS. Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING article .
    • Disconnect: Passenger Seat Side Air Bag C313.
    • Disconnect: Passenger Seat Horizontal Motor C332.
      • WARNING: Make sure no one is in the vehicle and there is nothing blocking or placed in front of any air bag module when the battery is connected. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.
    • Connect the battery ground cable. Refer to BATTERY, MOUNTING & CABLES -- FUSION, MILAN & MKZ article.
      • NOTE: During the following step, the voltage being measured changes polarity dependent upon which direction the seat control switch is activated.
