Inspection and Verification

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

Verify the customer concern.

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.

Data Link Connector (DLC)
Wiring, terminals or connectors

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 Integrated Diagnostic System (IDS) 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 AE , to diagnose No Power To The Scan Tool.
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 OASIS tab on the technician service publication website) retrieves the PCM part number.
- GO to PINPOINT TEST A , to diagnose The PCM Does Not Respond To The Scan Tool.
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 .
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).
- If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART .
