Self Study Program 971603 – Audi Data Bus Technologies

Self Study Program 971603 – Audi Data Bus Technologies PDF. Data Bus Technology. The demand for more luxury features and increased comfort in vehicles creates an ever-increasing need for more capable and more complicated vehicle electronic systems. Data bus technology makes it possible to form a complex network of electronic control modules and sensors that can communicate with each other and share data across the entire network without the size, complexity, expense and other limitations of a conventional wiring harness.

Audi’s introduction of Controller Area Network or CAN data bus technology in the mid-’90s was a first, important step toward the exchange of increasing amounts of data between control modules.

The first portion of this Self-Study Program describes basic functions of CAN-bus systems in general, and goes on to cover specific functions, diagnosis and testing for Drivetrain, Convenience and Infotainment CAN bus systems.

The latter portion of this Self-Study Program describes the single wire Local Interconnect Network (LIN) data bus, Media Oriented Systems Transport (MOST) fiber-optic data bus, and wireless data transmission technology used in the latest Audi vehicles.

Purpose of a CAN-bus System

The CAN-bus system provides the following advantages as an overall system:

  • Data exchange between control modules takes place on a uniform platform or protocol, with the CAN-bus acting as a data highway
  • Systems involving several control modules, ESP for example, can be implemented efficiently
  • System expansions and additions of optional extras are easier to implement
  • CAN is an open system that permits adaptation to various data transfer media, such as copper wires or fiber-optic cables
  • CAN is used for control module diagnosis, replacing the actual K-wire with a so-called virtual K-wire
  • System-oriented diagnosis is possible across systems employing several control modules
