Question
Why do CAN-FD networks experience more " CRC error" faults than classic CAN?
Answer
CAN-FD's larger data payloads (up to 64 bytes) increase the risk of data corruption during transmission.
Explain
Classic CAN uses 8-byte payloads, while CAN-FD handles more data—making CRC (cyclic redundancy check) failures more likely if wiring is degraded. CHEPQ CAN-FD analyzers highlight CRC error locations (e.g., near the ABS module) and recommend harness shielding upgrades to reduce EMI interference.
