Controller Area Network (Can): Overview

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2018 Audi A3 Quattro, 2017 Audi A3 Quattro, 2016 Audi A3 Quattro, 2016 Audi A3, and 2015 Audi A3 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

The Controller Area Network (CAN) bus is a message - based protocol that allows control units and devices to communicate with each other using a shared network. With this system, control units of the various electronic systems are no longer interconnected by multiple separate cables. This does away with a large number of electrical connections and results in a reduced likelihood of failure of the device network.
