- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
- 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 -- FUSION, MILAN & MKZ article, No Power To The Scan Tool, to diagnose no power to the scan tool.
- 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 -- FUSION, MILAN & MKZ article to diagnose no response from the SJB.
- Carry out the network test.
- If the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ article.
- If the network test passes, retrieve and record Continuous Memory Diagnostic Trouble Codes (CMDTCs).
- Clear the CMDTCs and carry out the self-test diagnostics for the SJB.
- If the DTCs retrieved are related to the concern, go to SMART JUNCTION BOX (SJB) DTC CHART . For all other DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES -- FUSION, MILAN & MKZ article.
- If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART .
