<p>PROBLEM TO BE SOLVED: To provide an electronic control device having a non-volatile memory high in memory efficiency. SOLUTION: In a step 100, it is discriminated whether an IG switch 21 is an on-state or not. In a step 110, the total number of times of start of each memory EM1a-EM1e of an EEPROM 19 is stored in each memory RM2a-RM2e of a RAM 27. In a step 120, it is discriminated whether a starter 33 is driven or not. In a step 130, the number of times of start of this time is counted up, and stored in a memory RM1 of the RAM 27. On the other hand. In a step 140, it is discriminated whether the IG switch 21 is switched from ON to OFF or not. In a step 150, the minimum value of the total number of times of start stored in the memories RM2a-RM2e of the RAM 27 is detected. In a step 160, the number of times of start of this time is added to the minimum value and the total number of times of start is calculated. In step 170, the total number of times of start is written in a memory having he minimum value of the EEPROM 19.</p> |
