Inspection and Verification

WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: If a new ABS module is installed, it must be configured. Refer to MODULE CONFIGURATION article.
  1. Verify the customer concern.
  2. Verify the stoplamps operate correctly by applying and releasing the brake pedal with the ignition switch in the OFF position. If the stoplamps do not operate correctly, refer to EXTERIOR LIGHTING article. If the stoplamps operate correctly, proceed to the next step.
  3. Visually inspect for obvious signs of mechanical or electrical damage.

  4. If the cause is not visually evident, connect the scan tool to the data link connector (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.
  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.
  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.
  7. Carry out the network test.
    • If the network test passes, retrieve and record continuous memory diagnostic trouble codes (DTCs).
  8. Clear the continuous DTCs and carry out the self-test diagnostics for the anti-lock brake system (ABS) module.
  9. If the DTCs retrieved are related to the concern, go to Anti-Lock Brake System (ABS) Module 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 .
    NOTE: Always retrieve the continuous DTCs after running the self-test.
    NOTE: For a complete master list of DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES article.
