Abstract

Actuator configuration, in particular, for actuating an injection valve of an internal combustion engine, includes an electrically activated actuator, a power switch for activating the actuator, a control input for receiving a control signal for actuating the power switch from an external control unit through a control line, and a diagnostic circuit connected at an input end to the actuator and/or to the power switch. For sensing the operating state, the control input is connected to at least a switching element in order to influence the electrical input characteristics, and the diagnostic circuit is connected at the output end to the switching element in order to influence the input characteristics as a function of the operating state and, as a result, to permit remote diagnostics by the external control unit through the control line. A method for actuating an injection valve of an internal combustion engine is also provided.
