Component Description: PDM

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.

For the power window function, the PDM receives power window commands from the passenger door window control switch or from the DDM through the MS-CAN.

For the power mirror functions, the PDM operates as follows:

RH exterior mirror glass position by supplying voltage and ground to the exterior mirror motors based on messages from the DDM.
When the heated mirror function is selected, it supplies voltage and ground to the RH exterior mirror glass heating element based on messages received from the FCIM.
When the memory mirror function is selected, it supplies the voltage and ground to the RH mirror motor and monitors the potentiometers to determine the mirror glass position. Memory mirror positions are stored in the PDM memory.
