In previous EnginEEringTheJigsaw episodes we've mentioned OBD in the context of #VehicleDiagnostics and talked a little about its history and what it is for, it's time to fill in the gaps though, what is OBD On-Board Diagnostics?

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: youtube.com/hashtag/engineeringthejigsaw
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! | #Engi...
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: www.vector.com/int/en/know-how/engineering-the-jig…
Of course, we are also happy if you write a comment directly here under the video!

The emission characteristics of vehicles are monitored by the legally prescribed on-board diagnostics (OBD). Each emission-relevant ECU must therefore support the OBD diagnostic. If exhaust-related errors occur (for example, a misfire), they are stored in the fault memory of the ECU and the driver is warned by an indicator, the so-called MIL (malfunction indicator lamp). Using an OBD diagnostic tester, the stored DTC (diagnostic trouble code) can later be read and analyzed.
Emission-relevant ECUs are no longer limited to the powertrain. Therefore, more and more automotive suppliers face the challenge to develop OBD-capable ECUs. Vector supports you with powerful tools and embedded software: www.vector.com/int/en/products/solutions/diagnosti…
