In order to research the mechanism of automotive failure diagnose and to improve, as well as to explore a new perspective to a find automotive failure diagnose quickly. This paper is based on the empirical data to analyze Xian’s some 4S shop and its self-organized criticality proposed a new suggestion. In this paper, we analyze in depth the data of automotive failure running status and diagnose index of different period between 2014, based on the theory of automotive failure diagnosed complexity and self-organized criticality, and thus proves the characteristics of power-law under which lies the related scale. The result shows us that, automotive failure diagnose system is a dynamical system that’s both extensive and dissipative. In addition, when STATUS is under 20 or less and TPI is above 6, the scale of influenced districts caused by index in automotive diagnose system and the related frequency fits the law-power distribution, and the rising of automotive will reach the state of self-organized criticality, and meets the characteristic of self-organized criticality.
