Component Description: DDM

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 Driver Rear Door Module (DRDM) through a LIN  and to the PDM  through the MS-CAN  .

For the power mirror function, the DDM  controls the LH  exterior mirror glass position by supplying voltage and ground to the LH  exterior mirror motors based on inputs from the exterior mirror control switch. When the RH  exterior mirror is selected, the DDM  forwards the movement requests to the PDM  through the MS-CAN. To control the heated mirror function, the DDM  supplies voltage and ground to the LH  exterior mirror glass heating element based on messages received from the FCIM  . For the memory mirror function, the DDM  supplies voltage and ground to the LH  mirror motor potentiometers. The DDM  monitors the feedback from these potentiometers to determine the mirror glass position. Memory mirror positions are stored in the DDM  memory.
