In this paper, a simple and practical C + + algorithm and the basic mathematical theory of fast, practical electronic control diesel online fault diagnosis research. First of all, the unique design of the fault code, according to the principle of the fault code, the fault has been classified. Then, making full use of the framework formed by fault code compilation, the basic fault diagnosis algorithm has been compiled. Then, the algorithm design of multi-parameter fault and complex fault diagnosis is carried out. Finally, in order to improve the extended function of the fault library, an “unknown fault” processing function is designed. In addition, software reliability studies were conducted. The simulation results show that the system is reasonable in design and reliable in operation, and achieves the expected goal. It proves the feasibility of practical and simple fault diagnosis algorithm
