Basics, Protocols and Future trends
This comprehensive course introduces learners to the principles, technologies, and evolving practices in automotive diagnostics. From traditional On-Board Diagnostics (OBD-II) to advanced Unified Diagnostic Services (UDS) and predictive maintenance (prognostics and health management) it equips automotive professionals with the knowledge to confidently identify, interpret, and respond to vehicle faults.
You will learn how diagnostics fit into the vehicle development lifecycle, explore fault detection strategies (model-based and data-driven), and understand the role of legislation in shaping diagnostic standards like ISO 14229 and SAE J1979. Real-world systems are described with a worked example of a diagnostic system for a dual-clutch transmission, which is used to illustrate software development in modern vehicles.
The course also covers UDS message structure, OSI layer mapping, and security implications—highlighting how diagnostic ports can be exploited if not secured. As vehicles become more connected, the course discusses the integration of diagnostics with telematics, over-the-air updates, and the shift toward cloud-based monitoring and prognostics.
Ideal for automotive engineers, technicians, tool developers, and trainers, this course blends theory with applied examples to build deep competence in vehicle diagnostics. Whether you’re in the workshop or designing the next generation of ECUs, this course will elevate your understanding and readiness for tomorrow’s vehicles.
At the end of the technical sections, a short quiz aids the learning process. These are optional, and the answers are shown on the slide following the quiz.
