2009 Mercury Milan Premier, 3.0 1, AWDSECTION Notes
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify the customer concern.
  2. Visually inspect the following for obvious signs of mechanical or electrical damage.
    VISUAL INSPECTION CHART

    Mechanical Electrical
    • Engine oil level
    • Door adjustment
    • Engine coolant level
    • Fuel tank
    • Fuel evaporative system
    • Tire size
    • Smart junction box (SJB) fuse(s):
      • 7 (10A)
      • 22 (10A)
      • 28 (10A)
    • Miniature bulb(s)
    • Circuitry
    • Instrument cluster
    • Message center switch
    • Odometer/trip odometer reset switch
  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
    4. NOTE: Make sure to use the latest scan tool software release.
  4. If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
    5. NOTE: The vehicle communication module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.
  5. If the scan tool does not communicate with the VCM:
    • Check the VCM connection to the vehicle.
    • Check the scan tool connection to the VCM.
    • Refer to MODULE COMMUNICATIONS NETWORK article, No Power To The Scan Tool, to diagnose no communication with the scan tool.
  6. If the scan tool does not communicate with the vehicle:
    • Verify the ignition key is in the ON position.
    • Verify the scan tool operation with a known good vehicle.
    • Refer to MODULE COMMUNICATIONS NETWORK article to diagnose no response from the powertrain control module (PCM).
  7. Carry out the network test:
    • If the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK article.
    • If the network test passes, retrieve and record the continuous memory DTCs.
  8. Clear the continuous DTCs and carry out the self-test diagnostics for the instrument cluster, anti-lock brake system (ABS) module, PCM, SJB and restraints control module (RCM).
  9. If the DTCs retrieved are related to the concern, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Index, Smart Junction Box (SJB) Diagnostic Trouble Code (DTC) Index or the Powertrain Control Module (PCM) Diagnostic Trouble Code (DTC) Index. For all other DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES article.
  10. If no DTCs related to the concern are retrieved, go to Symptom Chart .
