Abstract
When a non-volatile memory such as an EEPROM has a trouble code storage area and a status information area, status information is stored in the status information area after completion of storage of a trouble code in the trouble code storage area. Even when storage of the trouble code in a second storage area is interrupted due to a power fault with a result of three area discrepancy, the storage of the trouble code in the storage area is determined as not complete based on the status information, thereby leading to an appropriate data recovery of the trouble code in the trouble code storage area for an improvement of storage reliability of a vehicular memory management apparatus.
