Abstract:
An exemplary system includes a hydraulic device configured to operate at a fluid pressure. A sensor is configured to measure fluid pressure in the hydraulic device and generate a pressure signal representative of the measured fluid pressure. An actuator configured to regulate fluid flow to the hydraulic device. A control module is configured to identify a fault pending condition based on the measured fluid pressure, increase the fluid pressure in the hydraulic device during the fault pending condition, and iteratively enable and disable the actuator during the fault pending condition to determine if the actuator has failed.
