Automotive CAN Bus and In-Vehicle Networks

Understanding the digital nervous system of modern vehicles

Today's vehicles are more computerised than ever. From engine and electric drive control to lighting, braking, infotainment and safety systems-everything is connected. At the heart of this digital transformation is the CAN Bus: a communication network that allows electronic control units (ECUs), sensors, and components to talk to each other quickly and reliably.

As vehicle systems grow more advanced, technicians face a new challenge: diagnosing faults in a world where wires are fewer, but complexity is greater. While networking has helped simplify the physical layout of vehicles, it's made fault finding harder-especially for independent garages and workshops without access to manufacturer tools or software.

This book is written for those working in automotive repair, training, or study. Whether you're just starting out or looking to deepen your understanding, it explains how CAN Bus and other in-vehicle networks are laid out, how they operate, and how to test them using tools you can actually get your hands on.

Inside, you'll find:

-Clear explanations of how vehicle networks work

-Practical advice on fault finding and diagnosis

-Step-by-step guidance using accessible tools

-Troubleshooting examples to build confidence
