Question
How does CAN bus dominant bit timeout fault diagnosis isolate persistent faults?
Answer
It identifies modules stuck in dominant state for extended periods.
Explain
Persistent dominant bits block all communication. CHEPQ CAN analyzers detect long-duration dominant bits, isolate the faulty module via power cycling, and verify transceiver functionality. This restores full network communication quickly.
