摘要：
The invention relates to a protective circuit for a controlling element (100) of an electrically controlled brake booster, comprising a first and a second line (103, 104), whereby two potentials feed the connections of the controlling element, a first electronically actuated switch (106, 206) provided in the first line (104), a control device (112, 235 - 237) switching the first switch with a first control signal (S1), preferably a pulse width modulated control signal, and a second electronically actuated switch (105, 205) provided in the second line (103), wherein the control switch switches the second switch with a second control signal (S2). The method for testing the protective circuit comprises a step wherein at least one potential on at least one connection of the controlling element is tested when both switches are opened.
