Automobile electr onic tech no logy has becomea symbol of the n ati onal auto in dustry developme nt. Automobile suspe nsion is the fun cti on of conn ecti on in the body and wheels, with proper rigidity supporting wheels, and absorb the impact of the pavement, improve the vehicle comfort peace obey; Also can stable the car, improve handling. Suspension effect of ride comfort and handling stability, have conflicting links. Electronic control suspension under the control of electronic con trol devices, can accord ing to the outside world to accept the in formati on or the change of the state of the vehicle itself, which can adjust the dynamic adaptive sex, n amely electr onic con trol suspe nsion has no fixed suspe nsion stiff ness and damping coefficient. As the change of road conditions and driving with the requireme nt of the n eed to automatically adjust, fun dame ntally solve the contradiction between ride comfort and handling stability, improve the use performanee of the car. This paper not only to the wide application of electronic control suspension system structure, working principle of the system is expounded, and the fault type and the causes were an alyzed, and also use case also has made the detailed in troduct ion of the diag no sis process Keywords: electr onic con
