Advanced CAN Diagnostics: CAN Error Frames TrainingĀ  (2-day course)

CAN physical layer adapter
CAN bus hub connecting 3 ECUs

The CAN Error Frames training course isĀ for engineers and technicians already familiar with Controller Area Network basic electrical troubleshooting . This training focuses on Error Frames and intermittent issues.

Course objectives include best design practices for a robust CAN system, causes of signal degradation and an in-depth discussion of error frames: their mechanism as well as techniques to identify their source.

Demo Lab includes experiments to emulate real-world conditions in the physical layer and generation of error frames.

Course Duration: 2-day, Delivery: at customer location
