Abstract
In a method for operating a tank device of a motor vehicle having a tank and a valve which is adjustable by a driver stage connected to an energy supply, the valve is closed in response to an ascertained fault. Based on the fault, two output signals are formed for closing the valve: one of the output signals represents a relay signal and interrupts the energy supply to the driver stage.
