Vehicle Diagnostics: What Is UDS? |

In Episode F18, we covered On Board Diagnostics, specifically #OBD-II, and how this was introduced in the 1980s and -90s to control emissions (pollution). Has everything stood still for 30 years, though? And what about #VehicleDiagnostics that don't relate to a combustion engine? Answers to these questions and more may be found in this episode!

CONNECT WITH ENGINEERING THE JIGSAW

#EnginEEringTheJigsaw is a new series from #VectorInformatik that explains the technologies and concepts that are being built into the electrical/electronic (‘E/E’) systems of modern vehicles, and how Vector helps engineers to simplify their daily work: https://www.youtube.com/hashtag/engin...

To help you approach the episodes, we are grading them according to the level of content, as ‘foundation’, ‘intermediate’ or ‘advanced’. For more information on the series, please watch our introduction episode:    • Welcome to EnginEEring the Jigsaw! | ...  

Please get in touch with us if you want to suggest topics relevant to modern vehicle E/E systems that you’d like us to cover, or if you have any questions on the content: https://www.vector.com/int/en/know-ho...

Of course, we are also happy if you write a comment directly here under the video!

FURTHER RESOURCES

Unified Diagnostic Service (UDS) according to the #ISO14229 standard is a protocol used by diagnostic systems to communicate with ECUs in vehicles. The protocol is used to diagnose errors and reprogram ECUs. For example, it is possible to read and delete the fault memory of an ECU or to flash a new firmware on the ECU.

UDS is called "Unified" because it combines and consolidates standards such as KWP 2000 (ISO 14230) or Diagnostics on CAN (ISO 15765) and is independent of vehicle manufacturers.

#VectorInformatik supports UDS in its diagnostic and flash relevant products as well as embedded solutions: https://www.vector.com/int/en/product...
