Abstract

PURPOSE: To make reliable engine control possible by diagnosing by an abnormality diagnosing circuit whether a power circuit and load are abnormal and by inhibiting a driving circuit from operating when so.
CONSTITUTION: Driving circuit 200 is providing for each of various control loads and each load is driven by a control signal output by a control circuit. Then, abnormality diagnosing circuit 260, diagnosing whether power circuit 220 and loads are abnormal, inhibits circuit 200 from operating and also sends an alarm in case of abnormality such as when circuit 200 is abnormal and a car is disabled to run. Further, when the control circuit is abnormal, backup circuit 280 generates a control signal by simulating to back the operation of circuit 200 up. Consequently, engine control of reliance can be exercised.
