CAN-bus network that connects various control modules in the vehicle.


CAN-bus is the communication backbone of modern vehicles.

It is an internal vehicle communication network that interconnects components inside a vehicle such as micro controllers, devices and electronic control units without needing a central host computer. The main advantage is that it reduces the amount of wiring required using older analogue methods thereby reducing vehicle weight substantially.
It was developed by Robert Bosch in 1983 and was then officially released as a communications protocol for vehicles in 1986 by the Society of Automotive Engineers (SAE) congress in Detroit Michigan.

This method allows for various controllers in the vehicle such as the engine, transmission, air bags, braking systems, cruise control, power steering, windows, doors, mirrors, battery and recharging systems to talk to each other. It is critical these systems communicate with each other as they are dependent on each other for collecting information from various sensors as well as sending information to activate various functions. This new network allows for the development of very complex safety and comfort functions.
Some modern vehicles have up to 70 different electronic control units that send messages to each other. It is therefore critical that all the safety and comfort features are not negatively impacted by attaching a trailer harness.

The JaegerCANtrol module microprocessor is programmed for each specific vehicle make and model to ensure seamless communication through the vehicle CAN-bus system thereby enabling central control of all trailer lighting functions.
