Abstract
A method for testing a reservoir warning apparatus of a fluid reservoir for a hydraulic motor vehicle brake system, with the reservoir warning apparatus comprising a switching unit with at least one reed contact as the switching element. In order to find all possible faults in the reed contact, a dynamic contact resistance and a transient response of the reed contact are measured at the preassembled switching unit.
