Abstract

A method of operating a steering system having a rotatable steering control, a steering actuator having a rod movable along a range of travel, a rotary device coupled to the steering control, and a valve assembly disposed between the rotary device and the steering actuator includes rotating the steering control in a first direction, displacing the rod toward an end of the range of travel, and determining when the rod reaches the end of the range of travel. The method also includes, after determining, actuating the valve assembly from a first position in which the rotary device is not in fluid communication with the steering actuator, to a second position in which the rotary device is in fluid communication with the steering actuator, and inhibiting further rotation of the steering control in the first direction due to back pressure on the rotary device.
