The invention discloses an electronic control air suspension system component testing method and system, and relates to the technical field of suspension system performance testing, and the method comprises an air spring testing step, and the air spring testing step comprises the steps: sequentially selecting a plurality of air pressure values as a group of loads of an air spring according to the working air pressure range of the air spring; respectively applying a corresponding constant force to the air spring in an initial state corresponding to each load of the air spring so as to carry out air inflation and deflation tests on the air spring, thereby respectively obtaining the air inflation flow and height of the air spring at each sampling moment and the deflation flow and height of the air spring; and a corresponding load-flow-height inflation model and a corresponding load-flow-height deflation model are constructed on the basis. According to the test method and system, the relation between the inflatio
