Driver Door Module (DDM) (4/213) [2017-2022]: Description

The Driver Door Module (DDM) controls the operation of the lock, window and rear view mirror on the driver's door. The control module also controls a variety of lights that are activated upon entering or exiting the vehicle and the turn signals in the driver's side rear view mirror.

The operational commands to the control module come from the lock switch, door handle, the Driver door switch cluster DDS and the Central Electronic Module (CEM). The Driver Door Module (DDM) and the Passenger Door Module (PDM) are physically identical; the only difference between them is the software.
