Pinpoint Test U : The Generic Function Module (GFM) (Cd Player) Does Not Respond To The Diagnostic Scan Tool: Notes

WARNING: This page is about a different car, the 2015 Lincoln MKZ. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Power Distribution for schematic and connector information.

Normal Operation and Fault Conditions 

The GFM communicates on the HS-CAN3. Diagnostic messages are sent/received between the DLC and the diagnostic scan tool through the HS-CAN2 circuits at the DLC, and are translated through the GWM to the HS-CAN3.
