Inspection and Verification

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify the customer concern.
  2. Visually inspect for obvious signs of electrical damage.
    • If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

        • 24 (15A) (Data Link Connector (DLC), Steering Column Control Module (SCCM), Satellite Digital Audio Receiver System (SDARS), Tire Pressure Monitor Module (TPM))
        • 26 (5A) (SCCM)
        • 28 (15A) (Circuit Deactivation Ignition Module (CDIM))
        • 29 (20A) (Accessory Protocol Interface Module (APIM), Audio Control Module (ACM), Global Positioning System Module (GPSM))
        • 31 (5A) (Trailer Brake Control (TBC))
        • 33 (10A) (Restraints Control Module (RCM))
        • 35 (5A) (Parking Aid Module (PAM) Trailer Brake Control (TBC))
        • 37 (10A) (Auxiliary Heater Control Module (AHCM))
        • 38 (10A) (Audio Control Module (ACM)
        • 46 (10A) (HVAC module)
      • DLC
      • Wiring, terminals or connectors
  3. Connect the scan tool to the DLC.
      NOTE: Make sure to use the latest scan tool software release.
      NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.
    • If the computer running the Integrated Diagnostic System (IDS) software does not communicate with the VCM:
      • Check the VCM connection to the vehicle.
      • Check the scan tool connection to the VCM.
      • GO to PINPOINT TEST W  to diagnose no power to the scan tool.
  4. Establish a scan tool session.
      NOTE: The scan tool first attempts to communicate with the PCM, after establishing communication with the PCM, the scan tool then attempts to communicate with all other modules on the vehicle.
    • If an IDS session cannot be established with the vehicle, (IDS may state "No communication can be established with the PCM"):
      • Choose "NO" when the scan tool prompts whether or not to retry communication.
      • Enter either a PCM part number, tear tag or calibration number to identify the vehicle and start a session. The PCM part number and 4-character tear tag are printed on the PCM label. If the PCM part number cannot be found, a base part number search on the HVBOM application (under the On-Line Automotive Service Information System (OASIS) tab on the technician service publication) retrieves the PCM part number.
      • GO to PINPOINT TEST A , The PCM Does Not Respond To The Scan Tool.
  5. Carry out the network test.
    • If the network test passes, retrieve and record the continuous memory DTCs and proceed to Step 6.
    • If the network test fails, GO to SYMPTOM CHART  to diagnose the failed communication network.
    • If a module fails to communicate during the network test, GO to SYMPTOM CHART .
  6. Retrieve and review the DTCs.
    • If the DTCs retrieved are related to the concern, go to DTC CHARTS . Follow the non-network DTC diagnostics (B-codes, C-codes, P-codes) prior to the network DTC diagnostics (U-codes). For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in MULTIFUNCTION ELECTRONIC MODULES .
    • If no DTCs related to the concern are retrieved, verify the symptom. GO to SYMPTOM CHART .
