Abstract
A circuit for correcting a fault in an automotive system having at least two operating states includes an actuator mechanism for placing the system into one of at least two operating states and a switching mechanism, such as a relay, operatively connected with the actuator mechanism for driving the actuator mechanism upon passing a current through the switching mechanism. The circuit further includes a fault warning mechanism for detecting an inability of the actuator to place the system into a desired operating state and for generating a fault warning signal in response to the detection as well as a control unit for activating the switching mechanism according to a predetermined sequence upon generation of the fault warning signal to correct the inability of the actuator mechanism to place the system into a desired operating state.
