摘　　要：介绍了CAN低速网的波形特征,系统总结了CAN-H和电源的正极端短路、CAN-H线路断路、CAN-H和电源负极端短路、CAN-H和CAN-L之间短路、CAN-L和电源的负极端短路、CAN-L和电源的正极端短路、CAN-L线路断路7种故障的波形,为CAN线的学习者及汽车检测与维修提供了参考。This paper introduces the waveform characteristics of CAN low-speed network. The system summarizes the positive short-circuit of CAN-H and power supply, the disconnection of CAN-H line, short circuit of CAN-H and negative terminal of power supply, short circuit between CAN-H and CAN- CAN-L and the power of the negative terminal short-circuit, CAN-L and the power of the positive terminal short circuit, CAN-L line break seven kinds of fault waveform for the CAN line learners and vehicle detection and repair provides a reference.
