ABSTRACT:
The data processing unit of an engine control apparatus constantly fetches signals flowing from the sensors and signals flowing to the actuators, and decides whether the respective fetched signals are normal or abnormal to thereby store the results of the decision as diagnosis data in a random access memory.
The data processing unit stores a predetermined code in a predetermined area of the random access memory, carries out the engine control data processing operations in accordance with the diagnosis data, and writes the predetermined code in the predetermined area of the random access memory and clears data of all areas of the random access memory other than the predetermined area to thereby carry out the engine control data processing when the read data is determined not to be equal to the predetermined data.
