ABSTRACT:
An abnormal lifting cycle of a work machine lift component can be indicative of operator error and/or a fault within a lift component coupler. The present disclosure includes a method of detecting a fault for a lift component coupler of a work machine. Pressure within at least one hydraulic cylinder of the coupler is sensed during at least a portion of a lifting cycle of the lift component. A condition of the lifting cycle can be determined by detecting a magnitude of asymmetry within a plurality of the sensed pressures. An abnormal condition of the lifting cycle is indicated if the magnitude of the asymmetry of the plurality of the sensed pressures is outside of a predetermined range of asymmetry.
