1. A method for determining a faulty component in a system having a plurality of interacting components, comprising:

  • generating, by a plurality of diagnosis devices, a plurality of lists of potentially faulty components using a corresponding plurality of different diagnosis algorithms implemented independently of each other;

    assigning, for each potentially faulty component, an error value corresponding to a probability of a defective function of each potentially faulty component as a function of a symptom;

    for at least one set of components of the system, linking, by an evaluation device, the error values to form an error score value for each potentially faulty component as a function of the plurality of lists;

    assigning a respective error score value to each potentially faulty component; and

    determining the faulty component based on the respective error score value assigned to each potentially faulty component.
