Question
How to diagnose CAN-FD extended frame format faults?
Answer
It resolves communication failures with extended 29-bit message IDs.
Explain
CAN-FD supports standard (11-bit) and extended (29-bit) IDs. CHEPQ CAN-FD analyzers verify extended frame transmission/reception, detect ID formatting errors, and check module compatibility. This ensures communication with ECUs using extended IDs (e.g., ADAS, EV powertrain), avoiding network segmentation.
