Driver Door Module (DDM)
WARNING: This page is about a different car, the 2021 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 driver door window control switch through a LIN. The DDM supplies voltage and ground to operate the driver door window regulator motor.
The DDM also communicates driver door window control switch requests to the PDM through the MS-CAN to operate the passenger door window regulator motor. PMI is required whenever installing a new module.
