Abstract
A method for detecting a trouble location in wire harnesses can easily detect a position of trouble such as breakage, short circuit, or the like in the wire harnesses without bringing enlargement and complication into the wire harnesses. This method includes the steps of: setting each of electric wires (2) in a main line part (4) and a branch line part (5) of a wire harness (1) as a sensing line, the wires (2) being juxtaposed to each other in the respective parts (4, 5); transmitting a pulse wave in a measuring line of a trouble electric wire in the wire harness and the sensing line corresponding to the measuring line at their ends by a pulse generating unit (11); receiving a pulse wave reflected at a trouble point and measuring a difference in time between the transmitted pulse wave and the reflected pulse wave by a synchroscope (12); and computing a distance from a measuring point to the trouble point in accordance with the difference in time and a pulse propagation velocity by a computing unit (13).
