Pinpoint Test C: SELECTSHIFT™ Does Not Operate Correctly

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.
  1. C1 CHECK FUSE 47 (10A) 
    • Check fuse: Battery Junction Box (BJB) 47 (10A).
    • Is the resistance less than 5 ohms? 
      1. Yes  : GO to C2  .
      2. No  : REPAIR circuit CBK03 (GY) for a short to ground. INSTALL a new fuse. CLEAR the DTCs. TEST the system for normal operation.
  2. C2 CHECK THE POWER CIRCUIT FOR VOLTAGE 
    • Disconnect: Selector Lever C3233.
    • Ignition ON.
    • Measure the voltage between selector lever harness C3233-8, circuit CBK03 (GY), vehicle harness side and ground.

      1. Yes  : GO to  C4.
      2. No  : GO to C3  .
  3. C3 CHECK THE POWER CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: BJB Fuse 47 (10A).
    • Measure the resistance between the output side of BJB fuse 47 (10A) and selector lever harness C3233-8 circuit CBK03 (GY), vehicle harness side.

    • Is the resistance less than 5 ohms? 
      1. Yes  : INSTALL a new PCM. REFER to ELECTRONIC ENGINE CONTROLS - 3.0L (4V) -- FUSION & MILAN article.
      2. No  : REPAIR circuit RE407 (YE/VT) for an open. CLEAR the DTCs. TEST system for normal operation.
  6. C6 CHECK CIRCUITS FOR A SHORT TO GROUND 
    • Disconnect: PCM C175B.
    • Measure the resistance between PCM C175B-23, circuit CET43 (GY) and ground.
