Driver Door Module (DDM)
Driver Door Module (DDM)
The DDM is an integral part of the vehicle security system. In conjunction with the BPM and SLCM via the SCP network, it controls door locking,
interior lighting, door window position and door mirror position. The DDM also provides an interface via the SCP network, between the driver door
switchpack and all door control modules which permits remote control of all door window positions.
