The number and complexity of control units used in automobiles has increased tremendously. It is therefore important to include diagnostics in the development process of control units from an early stage. This workshop will provide you with a basic understanding of diagnostics. You will gain a comprehensive view of the CANdelaStudio tool. Practical exercises will also help you learn how to create your own diagnostics database and use it for ECU diagnostics with CANoe’s Diagnostic Console and DiVa, the automated protocol validation tool.
