Abstract

PURPOSE:To automatically operate a diagnosis for the suction control decelerating device, by deciding whether good or not with a decision signal of intake suction and a decision signal of rotational speed duration time of the engine. CONSTITUTION:A setting of operating pressure of the intake suction is obtained by a comparator 10 and a potentiometer 11. A trailing edge of output waveform of the comparator 10 is operated by an inverter 15 and a multivibrator 16. An output of this multivibrator 16, according to whether within a range of the reference value, is outputted to a multivibrator 18 through an AND circuit 17. And a decision for whether a rotational speed of the engine lowers to a prescribed level is obtained by a circuit operation of a comparator 23 and a potentiometer 24 and the like, with an actuation made by an inverter 25 and a multivibrator 26 with the trailing edge signal of a comparator 23, and when within a range of the reference value, a multivibrator 28 outputs, and a diagnosis is operated for the suction control decelerating device by the output of an AND circuit 29.
