Abstract
A system and method for controlling access to a work vehicle includes limiting an unauthorized operator's access to the work vehicle by disabling an engine subsystem and additionally limiting access to another vehicle system such as an auxiliary fluid actuator, by disabling at least one of the auxiliary fluid actuators. In this manner, even if a thief hot wires the engine of the work vehicle, he will not be able to use the work vehicle since the engine and the fluid actuators and the fluid controller that controls the actuators are independently disabled.
