1. A dynamic diagnostic operational transducer fault detection system comprising, a first logic network being connected to a low level pressure offset circuit and to an operational transducer to transducer equivalence check circuit, said low level pressure offset circuit being connected to a second logic network, said operational transducer to transducer equivalence check circuit being connected to said first logic network and to an operational transducer to transducer comparison check circuit, said second logic network being connected to a pair of transducer offset test check circuits, said pair of transducer offset test check circuits being connected to a third logic network, said third logic network being connected to a pair of high level transducer fault detector circuits for distinguishing a transducer failure from a faulty dragging and/or stuck brake condition.
