DDM or PDM
The DDM and PDM control the operation of the power door locks, power windows, and the power mirrors. They communicate with each other and the BCM over the Medium Speed Controller Area Network (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 Programmable Module Installation (PMI) when replaced.
