The door control module (DCM), also called a door control unit (DCU), is a type of automotive electronic that provides intelligent control for vehicle doors, and their peripheral electric parts and components, that enable features such as power windows, anti-pinch technology, central door locking, rearview mirror adjustment, door lighting and more. The increased importance of DCM/DCU is inevitable in the context of advancing automotive electronic technologies, and the widespread applications of controller area network/ local interconnect network (CAN/LIN) bus technology, that drives the development of automotive data transmission, driver and passenger safety and comfort, vehicle weight reduction and design modularity.

A DCM needs circuitry for the following: power, power window drive, rearview mirror drive, heater drive, central door locking drive, lamp drive, CAN bus interface, key interface and more. These serve features such as power windows, rearview mirror folding and horizontal/vertical adjustment, electric heating and lighting. And, as functional requirements continue to increase, designs will only grow in complexity

Molex Door Control Module Connectors

As the market places increasing demands on DCMs, they are becoming smaller, lighter in weight and lower in cost; also, they are consuming less power. More importantly, functionality and scalability are both improving. As a result, DCMs are raising new requirements for their connectors. First, as DCM functionality is enhanced, different configurations have been adopted by different vehicle models, calling for flexible scalability: • 1-in-1 (1 DCM per door) • 2-in-1 (1 DCM for each side of the car) • 4-in-1 (1 DCM per vehicle, controlling all 4 doors) Because the mounting space for the DCM is restricted, the connector is required to have a lower and narrower profile. Also, to meet ergonomic requirements for connector operations, both the insertion and the withdrawal force must not exceed 75N.
