Vehicle buses provide the foundation for diagnostic communication in modern vehicles. This article explains the key bus systems used for diagnostic applications – from K-Line and CAN to CAN FD and Automotive Ethernet – and highlights their characteristics, applications, advantages and limitations throughout the vehicle lifecycle.
Read our article on how ZEVonUDS (SAE J1979-3) defines the standard for electric vehicle diagnostics using UDS and DoIP, enabling future-ready vehicle communication.
In this webinar, you will explore how OBD goes beyond fault code reading to enhance the testing and validation of modern vehicle systems. You will also gain practical insights into how these capabilities can be applied in real-world development and test scenarios.

Meet us at the SAE International On-Board Diagnostics Symposium from March 11-13, 2025 in Porto, Portugal. Our team, represented by Oliver Fieth and Julian Mayer, is looking forward to exchanging ideas with experts from the industry and discussing the latest developments in on-board diagnostics (OBD).
We look forward to discussing the latest developments in vehicle diagnostics with you at the OBD Symposium and presenting our innovations and solutions.
In this webinar you will learn the basics of diagnostic communication (UDS, DoCAN, DoIP). It also covers how UDS is used for diagnostic communication with a ZEV to read the VIN. Furthermore, a practical demo provides a graphical user interface of a diagnostic service tester.
Meet us at the SAE OBD Symposium 2024 in Amsterdam and join the presentation "Diagnostic Communication with a ZEV using UDS on IP (SAE J1979-3)” by Peter Subke. The presentation explains the extension of SAE J1979 and its "OBD Modes" to UDS and their application in ZEVonUDS for the diagnosis of ZEV drive systems, including the reading of the VIN using DoIP.
Visit Softing at the On-Board Diagnostics Symposium-Americas 2023, the industry's trusted resource for accessing automotive technologies, standards and regulatory information to meet emissions regulations from regulatory entities worldwide.
Meet Softing Automotive at the WCX World Congress Experience, April 18-20, 2023 in Detroit, MI, USA. On April 20 at 1:30 pm, Softing Automotive's Director of Business Development, Peter Subke, will speak about "UDSonCAN and OBDonUDS: CAN-Based Application Layer Protocols for the Diagnostic Communication between the In-Vehicle CAN and MVCI-Based External Test Equipment".
