Component Description: PDM
WARNING: This page is about a different car, the 2022 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
For the exterior power functions, when the RH exterior mirror is selected, the PDM supplies voltage and ground to the appropriate RH exterior mirror motor to drive the mirror glass in the desired direction based on messages received from the DDM through the MS-CAN.
For the exterior heated mirrors feature, the PDM is responsible for supplying voltage to the RH exterior mirror glass heating element based on messages received from the FCIM.
When a concern exists, the PDM is capable of setting and storing Diagnostic Trouble Codes (DTCs) for the RH exterior mirror motor drive circuits, position sensor circuits and mirror heater circuit.
PMI is required if installing a new module.
