Component Description: DDM

The DDM receives power window and power mirror commands from the power window and power mirror switches 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:

• 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 exterior mirror movement requests to the PDM through the MS-CAN.
