Abstract

A method for functional testing of an electromechanical fill level monitoring device. In order to test the plausibility of a signal emitted by a fill level monitoring device of a first pressure medium chamber, a forced actuation of this fill level monitoring device is carried from time to time. This forced actuation is carried out in that a pressure medium delivery unit in a pressure medium circuit having the first pressure medium chamber is activated for a predefined period. This delivers the pressure medium fill level monitoring device into a second pressure medium chamber via a pressure medium connection. On the basis of the signal profile output by the fill level monitoring device, the proper operation of the fill level monitoring device is inferred in the electronic control unit.
