Door Modules
NOTE:
Driver Door Module (DDM) is shown, the other door modules are similar.
The door modules provide the interface between the door latches and the Body Control Module/Gateway Module (BCM/GWM). The door modules provide door latches status information and enable the door motors on request from the BCM/GWM.
The rear door modules are also controlled by the BCM/GWM via the High Speed (HS) Controller Are Network (CAN) body systems bus. Additionally, the Driver Door Module (DDM) and the Passenger Door Module (PDM) also control the door mirror functions.
