Self Study Program 971903 – The Audi CAN Data Bus

VAG SSP 971903. In this Self-Study Program we will explain to you the design and function of the CAN data bus. The CAN data bus by Bosch is such a solution. It was developed specially for automobiles and is used by both Volkswagen and Audi. CAN stands for Controller Area Network and means that control modules are networked and interchange data.

A CAN data bus can be compared to a passenger bus.

While the passenger bus transports a large number of persons, the CAN data bus transports a large volume of information.
