Question
How to diagnose CAN bus recessive bit fault?
Answer
It identifies issues preventing the bus from returning to recessive state.
Explain
Recessive bit faults cause bus lockups. CHEPQ CAN analyzers measure bus voltage in recessive state, detect short circuits between CAN-H and CAN-L, or faulty transceivers, and verify termination resistance. This restores bus communication, preventing widespread network failures.
