A method for operating a control unit of a motor vehicle including a function unit and a monitoring unit which have a communication connection to one another. In a first check, the function unit is checked for errors, an error of the function unit being inferred if an error counter reaches a threshold value, and the monitoring unit and the function unit exchange first data with one another. In the event of a correct exchange of the first data, a positive change of the error counter is carried out. Otherwise, a negative change of the error counter is carried out. In a second check, the monitoring unit and the function unit exchange second data with one another. In the event of an incorrect exchange of the second data, a negative change of the error counter and a negative change of the threshold value are carried out.

Method for operating a control unit of a motor vehicle

A method for shutting down an electrically controlled component of a vehicle in a case of error of a processing unit, the component being controlled by a control circuit, which receives at least one control signal from the processing unit and controls the component as a function of the at least one received control signal, the processing unit outputting the at least one control signal to a control terminal, the processing unit being designed for outputting an error signal having a defined level to the control terminal in a case of error.
