A CAN (Controller Area Network) module for towbars is an electronic device that facilitates communication between a vehicle’s onboard systems and the towbar’s electrical components. It allows for the seamless integration of lighting, braking, and other trailer functions with the vehicle's control systems, ensuring proper signal synchronization and compliance with safety standards. The CAN module typically communicates through the vehicle’s existing CAN bus network, simplifying installation and improving the overall functionality of the towing setup.

Warning: CAN control units are not universal and are designed to fit specific vehicles. Always check the compatibility list in the product details, or alternatively, directly on the towbar page of your interest.
