In one example, an electronic system includes, a user interface comprising an input device, a first actuator and a second actuator, the first and second actuators dually actuated by the input device, and a controller, including a comparator, a programmable device, and executable instructions residing in non-transitory memory thereon to, receive first and second output signals from the first and second actuators, respectively, convert the first and second output signals to first and second real-time logic states at the comparator, input the first and second real-time logic states from the comparator to the programmable device, and determine a fault status of the first and second actuators based on the first and second logic states input to a state machine of the programmable device, wherein the first and second logic states input to the state machine include the real-time logic states and historical logic states stored at the controller.
