Component Description: DDM
WARNING: This page is about a different car, the 2023 Ford Bronco Sport. 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.
For the power mirror functions, the DDM operates as follows:
- LH exterior mirror glass position by supplying voltage and ground to the exterior mirror motors based on inputs from the master window control switch.
- Forwards the RH exterior mirror movement requests to the PDM through the MS-CAN.
- When the heated mirror function is selected, it supplies voltage and ground to the LH 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 LH mirror motor and monitors the potentiometers to determine the mirror glass position. Memory mirror positions are stored in the DDM memory.
