Beschreibung
Zusammenfassung:	A method of adjusting performance of an electronically controlled hydraulic system comprises the initial step of providing at least one electronically controlled hydraulic device having a control valve member operably coupled to an electronic actuator. The control valve member impacts a seat when the device is activated and de-activated. The electronically controlled hydraulic device is then activated according to an activation profile. The seat impacts of the control valve member are detected and recorded. The detected seat impact characteristics are compared to expected seat impact characteristics. A subsequent activation profile is then changed if the detected seat impact characteristics are substantially different from the expected seat impact characteristics
