ABSTRACT:
System and method for detecting a fault in a faulty network element of a bus network comprising two or more transmitters. The method comprises transmitting from one of the transmitter a signal of predetermined parameters to the bus network; receiving the signal; and determining if the first signal is followed by a tail that is an echo indicative of a faulty network element. The location of the faulty network element can be determined by transmitting from a second transmitter a second signal of predetermined parameters to the bus network; the second signal and, determining if the second signal is followed by a second tail that is an echo indicative of the faulty network element; and if tails are detected, determining by an algorithm executer the location of the faulty network element by triangulation.
