A pre-charging circuit for charging an intermediate circuit capacitor is provided having a first electronic component, a second electronic component and a diagnostic circuit. The diagnostic circuit is designed for functional testing of the first electronic component and/or of the second electronic component and comprises an energy source with a terminal voltage. A voltage drop can be induced on the first electronic component by the energy source, as a result of which the functional performance of the first electronic component and/or of the second electronic component can be tested. The diagnostic circuit has a diagnosis switch via which the energy source can be connected to the first electronic component in such a manner that the dropping voltage on the first electronic component corresponds to the terminal voltage.
