A system and method for determining a health status of a hydraulic system is disclosed. The system may comprise a controller configured to receive a request to determine a health status and in response to the request, automatically conduct a health test and determine the health status. The health test may include: move a member or the upper frame; receive information indicative of measurements associated with movement; determine one or more parameters; compare each parameter to a check range or value; and if the pump status, the main control valve leakage status, the in-line relief valve leakage status, the cylinder drift status or the cylinder seal leak status associated with the component is currently failing, predicted to fail or out of specification, identify the component as a service-needed on a display or log and activate an alarm.
