1. A method for detecting a fault in a wire harness, said harness having a main line and at least one branch line, a main plurality of sensing wires in said main line and a branch plurality of sensing wires in said branch line, said main plurality of sensing wires being juxtaposed to each other, said branch plurality of sensing lines being juxtaposed to each other, a measuring wire having said fault in said main line or said branch line, said measuring wire juxtaposed to said main plurality or said branch plurality;

  • transmitting a pulse wave in said measuring wire and a random one of said sensing wires at ends thereof;

    receiving a pulse wave reflected at said fault;

    measuring a difference in time between said transmitted pulse wave and said reflected pulse wave; and

    computing a distance from a measuring point to said fault based on said difference in time and a signal propagation velocity.
