Method and diagnostic facility for checking high-pressure tank valves, high-pressure tank system and motor vehicle with a high-pressure tank system

摘要

A method and diagnostic facility for checking a plurality of magnetic valves in a high-pressure tank system of a motor vehicle is described. A magnetic valve is activated for opening the magnetic valve. A pressure in a high-pressure tank system is measured while activating the magnetic valve. A valve is determined to be defective if during measuring the pressure a drop in pressure is found.
