Abstract

PURPOSE:To protect the control operation of an engine even in case of the destruction of the contents of a backup RAM by detecting the destruction of the contents of the backup RAM by making a comparison between the contents of the backup RAM and an ROM, and by initializing the contents of the backup RAM. CONSTITUTION:A CPU20 discriminates whether the storage contents of a backup RAM34 coincide with those of an ROM22 or not. When the both coincide with each other, it is judged that the contents of the RAM34 are normal, and the following processing is carried out as it is. When not, on the other, it is judged that the contents of the RAM34 are destroyed owing to a break of electric power supply, its drop, noises, etc., and all areas except the checking storage area of the RAM34 are initialized.
