Abstract: The increase of the number of automobiles and the diversification of types make the overall development of China's automobile field gradually become close to a virtuous cycle. From the perspective of the automobile field, the fault detection and maintenance of automobile anti-lock braking system is one of the key problems in the process of automobile development and application. Based on this, this paper starts a study. In the early years of Peugeot 307 cars and Passat B5 cars anti-lock braking system fault for the research content, first detail the antilock braking system (ABS) composition and principle, and on the basis of detailed analysis of the car fault, through professional diagnosis and exclusion to determine the real fault cause and location, to provide value reference for relevant staff.
