    Abstract: A method for verifying the operation of a cleaning device mounted on a motor vehicle, comprising at least one of the following steps: commanding a pump to inject cleaning fluid as far as at least one valve during a determined time period, the command to activate the pump being coupled with the keeping of the valve or valves in the closed state; at least one measurement of a parameter relating to the pressure of the cleaning liquid upstream of the valve or valves using at least one pressure sensor; comparing the measured parameter relating to the pressure against a predetermined expected value; and determining an operating status of the cleaning device on the basis of the result of the comparison between the measured parameter relating to the pressure and the predetermined expected value; and generating a warning signal in the event that the cleaning device is malfunctioning.
