Abstract: Controller area network (CAN) bus malfunctions can exert numerous influences on vehicles, such as local functional failure, decreased power, increased fuel consumption, and even circumstances where the vehicle cannot be accessed or started. This paper takes the 2019 Volkswagen Magotan B8L as the experimental platform, and with the aid of EveryCircuit software simulation and real vehicle tests, conducts experimental analyses on the CAN bus under different fault modes. Through the research methods and measured data in this paper, it is capable of providing references for the diagnosis and elimination of vehicle CAN bus faults, presenting an efficient and expeditious maintenance approach and thinking.
