Abstract: The invention relates to a method for detecting faults in a set of wires (25) to be tested comprising at least two wires each having an input end and an output end. The method comprises in succession a step (10) of connecting at least one wire undergoing analysis to a signal generator (26) and of grounding the other wires, a step (12) of generating a test signal on the channel undergoing analysis with the signal generator (26), a step (13) of acquiring and measuring the power of a first signal returned over at least one wire connected to the acquiring unit (29), and a step (14) of analyzing the integrity of the wire undergoing analysis using the power of the return signal of the wire in question and the analyzing unit (31). These steps repeat automatically, the wire to be tested being changed each time.
