摘要： In an vehicle-mounted engine control apparatus according to the present invention, a restart inspection means, which is simpler than an activation inspection means, is provided, and a means to be applied is selected by an initialization determination means. The contents of the restart inspection are limited to malfunction items detected by a periodic code inspection means during driving of the vehicle. As a result, the time that is required to restart a microprocessor when a malfunction occurs is shortened.

摘要： A sensor switch 111a connected to a constant voltage Vc via a breeder resistor 114a and dropper diodes 112a and 113a is connected to a microprocessor 120 that configures a wire abnormality detecting device 100, and the electric potential of the connection point between the dropper diodes 112a and 113a is inputted to the microprocessor 120 as a switch logic signal D1 via a signal wire 105 and a series resistor 131a. The signal voltage level of the switch logic signal D1 is inputted to the microprocessor 120 via an AD converter 123, and the microprocessor 120 cooperates with a program memory 121 to perform a determination of whether or not the signal voltage is in an abnormal intermediate voltage state. However, during a transitional period when the switch logic signal is changing between high and low, mistaken determination is prevented by avoiding abnormality determination.
