Abstract
PURPOSE: To carry out conduction test for vehicle having an extremely large number of lines to be tested, correctly and completely, through provision of a matrix establishing means in which a test voltage is impressed on one end of connecting wires for detecting the voltage at the other end of the wires.
CONSTITUTION: Connecting wires 2 extended from connecting plugs 6 provided in vehicle correspond to either of terminals A1 to An of matrix establishing unit 15 and connected to its output terminals B1 to Bn. When either one of the terminals A1 to An is selected by line number changing switch 16 and terminal Ai is pressed by judging element 18, it is transmitted directly to Bj. Line number (i) connected to line number (j) is provided with judging element 18 at the intersection of line Ai and row Bj, whereas NOT judging element 19 is provided for those combinations which are not electrically conducted. With such an arrangement, output of terminal Bj corresponding to line number (j) is measured while switching the selection switch 16 to all of the lines, and when it is detected that voltage is impressed to all of the terminals, it is judged that line number (j) is normal
