Pinpoint Test G: The Power Seat Does Not Move Horizontally/Vertically - Driver

WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition is ON.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
  1. G1 CHECK THE HORIZONTAL MOTOR FOR CORRECT OPERATION 
    • Operate the driver seat forward and rearward.
    • Will the seat move horizontally? 
    • Yes:  GO to  G5.
    • No:  GO to G2  .
  2. G2 CHECK FOR VOLTAGE TO THE DRIVER SEAT HORIZONTAL MOTOR 
    • Ignition OFF.
    • Depower the SRS  . Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
    • Disconnect: Driver Seat Side Air Bag C328.
    • Disconnect: Driver Seat Horizontal Motor C362.
      • 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 AND CABLES .
    • Measure the voltage between driver seat horizontal motor C362-1, circuit CPS28 (GN), harness side and C362-2, circuit CPS23 (GN/VT), harness side, while pushing the driver seat control switch forward and rearward.

    • Is the resistance less than 5 ohms? 
  5. G5 DETERMINE THE SEAT HEIGHT ADJUST FAILURE 
    • Operate the seat front and rear height adjustments.
    • Does the seat front and rear height adjust up and down? 
  6. G6 CHECK FOR VOLTAGE TO THE REAR HEIGHT MOTOR 
    • Ignition OFF.
    • Depower the SRS  . Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
    • Disconnect: Driver Seat Side Air Bag C328.
    • Disconnect: Driver Seat Rear Height Motor C363.
      • 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 AND CABLES .
    • Measure the voltage between driver seat rear height motor C363-2, circuit CPS26 (YE/BU), harness side and C363-1, circuit CPS27 (BU/BN), harness side, while depressing the rear height adjust switch up and down.
