Abstract
A method and a device for monitoring at least one output stage which is actuated by a microcontroller using an input signal having any pulse duty factor. The output signal from the output stage is averaged by an electrical circuit and compared to a setpoint value which is calculated from the input signal of the output stage. An error in the output stage is diagnosed when the averaged value deviates from the calculated setpoint value.
