Data are combined according to predetermined equations to yield intermediate diagnostic results. Intermediate diagnostic results are combined recursively according to fixed expressions to produce final diagnostic results relating to the state of the vehicle system under diagnosis. Fixed expressions may be algebraic, Boolean, fuzzy logic, statistical, or relate to an expert system.Other References
