Abstract
A method for determining a lack of capacity of a pump, actuated by an electric motor, of a hydraulic brake system of a motor vehicle comprises the steps of generating a hydraulic pressure in a first brake circuit of the brake system by means of a plurality of pump elements of the pump that are assigned to the first brake circuit, limiting the generated hydraulic pressure to a test pressure and simultaneously acquiring a motor-related parameter, and determining a lack of capacity of at least one of the pump elements on the basis of a comparison of the parameter with a comparison value.
