The invention relates to a computer-supported diagnostic system in which the physical structure of the technical system to be diagnosed is implemented in the form of a structural model. If a fault code occurs in a component of the technical system which is capable of self-diagnostics, and thus also in the structural model, the fault location is searched for with a parameterizable path search by means of the path search algorithm as a function of the fault which has occurred in the structural model. The parameterization of the path search succeeds here by virtue of fault-specific heuristics. A heuristic in the sense of the invention is here a software module which can be selected as a function of a fault which has occurred, which module contains a fault-specific evaluation algorithm, which contains information about the set of candidates which are to be included in the troubleshooting, and which contains rule lists with fault record conditions which are used for a fault decision by the evaluation algorithm. The fault location is found if a state variable of a component in the structural model meets a fault record condition.
