Driver Door Module (DDM)
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The DDM (if equipped) uses the medium speed CAN for communication with the diagnostic tool and other modules on the medium speed CAN. The DDM stores the driver's seat and mirror positions for recall.
Check the medium speed CAN circuits between the DDM C568a and the DLC C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the medium speed CAN, damage to the DLC C251, or damage to the DDM C568a.
