Abstract
The Magotan B8L near-light network transmission architecture and functional components are introduced,the near-light signal trigger circuit,main loop working circuit and network indicator circuit are analyzed,and combined with its light control circuit,the detection and diagnosis of Magotan B8 lighting system fault diagnosis is introduced from the aspects of diagnostic instrument diagnosis,voltage testing,waveform analysis,etc.Break the method.Finally,take the abnormal lighting of Magotan B8L near light as the case point.Through inspection,analysis and reasoning,the LIN bus control near-light failure is eliminated,which provides reference and reference for the efficient and accurate locking of similar electronic control faults.
