Summary

When connecting the Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) or Ford Diagnosis and Repair System (FDRS) to the DLC located on the driver side under the steering column at the GWM, make sure that the ignition is off before connecting the VCM. If the ignition is on or the engine is running during the connection, it can result in various warning lights being illuminated with diagnostic trouble codes (DTCs), no start or no crank conditions or the IPC inoperative. For Lincoln vehicles, this information is now listed in the Technical Inspection and Post Road Test Sections of ePDI on the PTS website. If a vehicle displays these issues, disconnect the equipment from the DLC and disconnect the vehicle battery. Wait 10 minutes and reinstall with the ignition off. Clear any DTCs present and retest.
