Test Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Ford RV Cutaway, 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
  1. AD1 CHECK FOR DTCS 
    • Access and record any DTCs.
    • Record the freeze frame data.
    • Clear the DTCs.
    • Carry out the KOEO and KOER self-test.

    Are any DTCs present? 

    Yes No
    REFER to DIAGNOSTIC TROUBLE CODE (DTC) DESCRIPTIONS . GO to  AD2.
  2. AD2 CHECK THE VEHICLE BATTERY POWER CIRCUIT 
    • Key in OFF position.
    • PCM connector disconnected.
    • Key ON, engine OFF.
    • Measure the voltage between:
      ( + ) PCM Connector, Harness Side ( - )
      VPWR - Pin B34, B46 Ground
    • Check for loose connections. Check for damaged pins or corrosion. Wiggle the harness while taking the measurements.

    Are the voltages greater than 10.5 volts? 

    Yes No
    GO to  AD3. REPAIR the open circuit. CLEAR the DTCs.
    REPEAT the self-test.
  3. AD3 CHECK THE PCM POWER RETURN CIRCUIT 
    • Key in OFF position.
