Abstract

The invention relates to a circuit arrangement of a circuit of an electrically controlled brake force booster, including a first and a second line that supply two potentials to the connections of the actuator, an electronically actuated first switch provided in the first line, a control device that switches the first switch with a first, preferably pulse-width modulated, control signal, and an electronically actuated second switch provided in the second line, wherein the control circuit switches the second switch with a second control signal. A process for testing this circuit arrangement includes the step of testing at least one potential on at least one connection of the actuator when both switches are open.
