Abstract

PURPOSE:To enable to perform all diagonosis of a main input output device based upon to a program, by outputting a given voltage corresponding to an abnormal condition of a solenoid at a given position of a throttle sensor or a car speed sensor in a car. CONSTITUTION:A speed sensor 1 generates the number of pulses corresponding to a running speed of a car, and a throttle sensor, consisting of a plural number of switch circuits, output a BCD signal corresponding to an opening degree of a throttle. Based on a said information, a microcomputer CP4 outputs a solenoid driving signal Ss, a power transistor TR9 is brought to ON, and a solenoid L10 is excited to cause a car speed to change. Short-circuit of the L10 is detected by a TR14, and a generating voltage Vd is applied to the CP4 to determine the trouble on the L10. If the L10 is released, the voltage Vd is brought to naught. Each trouble detecting information is stored in a memory 40. Additionally, the CP4 outputs a voltage proportioning the opening degree of the throttle or proportioning the car speed to a terminal DT.
