DDM or PDM

The DDM and PDM control the operation of the power door locks, power windows, and the power mirrors in the front doors. They communicate with each other and the BCM over the MS-CAN. They also send commands and receive feedback from the Driver Rear Door Module (DRDM) and Passenger Rear Door Module (PRDM) over a LIN for each module.

The DDM and PDM do not require PMI when replaced.
