초록

In this study, when a communication wire harness is defective due to long-term operation of a vehicle with a high-speed CAN communication network, the unique ID information of each controller and the oscilloscope waveform are analyzed to find defects. As a result of the experiment, it was possible to know whether the circuit of the main wiring was disconnected by the differential voltage analysis, and it was possible to confirm whether the sub-wiring was disconnected due to the generation of saw blade waveforms in the bus idle part. In addition, the fault location could be found with controller ID information and communication circuit analysis.
