Abstract: With the wide application of controller area network (CAN) bus technology in automotive field, solving CAN bus fault has become a necessary ability for automotive network engineers. From the perspective of automobile research and development, this paper first expounds the general idea of dealing with bus faults, then introduces several common CAN bus diagnostic tools, and finally describes the CAN bus faults encountered by the author in the actual project work in detail from the aspects of fault phenomena, diagnosis analysis and troubleshooting methods. It is hoped that the sharing of these cases can provide some practical experience and help for relevant personnel engaged in the development and application of automotive CAN network.
