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.
