Abstract

PURPOSE: To enable only the peripheral circuit to be sufficiently diagnosed as well by providing gate means between a function circuit element and a peripheral circuit element.
CONSTITUTION: To test a printed board unit except a function circuit part 2, a control signal is applied from a control signal input terminal 8 to electrically disconnect a gate part 5 and a gate part 6 from the function circuit part 2 and electrically short-circuit the gate parts 5 and 6 to each other by means of wiring 7. The input signal group inputted from a DC diagnosis device 9 via a signal cable 10 and a jack 11 passes through the gate part 5 past a peripheral circuit part 3, is bypassed by the wiring 7 and is transmitted to the gate part 6 and further from the gate part 6, the output signal group is outputted through the peripheral circuit part 4 to the DC diagnosis device 9 via a jack 12 and a signal cable 13.
