Driver Door Module (DDM)
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The DDM receives power window commands from the master window control switch through a LIN. The DDM supplies voltage and ground to operate the driver door window regulator motor.
The DDM also communicates master window control switch requests to the PDM through the Medium Speed Controller Area Network (MS-CAN) to operate the passenger door window regulator motor.
