Abstract
A pilot neutralizing system of a work vehicle may include a pilot neutralizer and a first sensor. The work vehicle may include a frame assembly having a first frame portion and a second frame portion and an actuating assembly used to pivot the first frame portion relative to the second frame portion. The pilot neutralizer is electrically coupled to a controller and is hydraulically coupled between the operator control member and the steering valve to selectively provide a communication of a pilot signal. When an articulation position reaches a cushion region during steering, the pilot neutralizer is de-energized or energized to change the pilot signal at the steering valve to resist the actuating assembly from moving. The first sensor is coupled to the pilot neutralizer and detects a first value to diagnose the pilot neutralizer to determine whether the pilot neutralizer is incorrectly in a de-energized state or an energized state.
