PROBLEM TO BE SOLVED: To easily specify an electric component control means in which a fault occurs when supplying a power supply voltage prepared by a power supply board to a plurality of electric component control means. SOLUTION: When trouble like a short-circuiting fault does not occur in each of electric component control boards, respective LED (LD01-LD10) are turned on. When trouble like short-circuiting fault occurs in association with a VSL in a certain electric component control board, an over current flows to cut a corresponding fuse and only the corresponding LED is turned off. When trouble like short-circuiting fault occurs in association with a VDD in a certain electric component control board, an over current flows to cut a corresponding fuse and only the corresponding LED is turned off. When trouble like short-circuiting fault occurs in association with a VCC in a certain electric component control board, an over current flows to cut a corresponding fuse and only the corresponding LED is turned off.
