Abstract

A method for operating a shutoff device for a device, in particular an internal combustion engine and/or an electric machine, in which an operating element for initiating a shutoff operation is provided, and in which a transmission path is provided via which a shutoff signal is transmitted from the operating element to the device in order to deactivate the device. The shutoff device is checked for proper functioning at least in part automatically, by automatically transmitting a shutoff signal, in particular from the operating element via the transmission path to the device.
