The reset check code is converted, the step(S14) clears all data stored in the RAM to control the component of the vehicle. If the reset check code is not converted, the step(S15) checks a predetermined main data storage address of the RAM. The step(S16) clears a remaining data of the RAM except the main data stored in the main data storage address, and continues the main routine. Thereby, the method for preventing a memory clear selectively clears a memory of ECU according to a discrimination result of a reset signal being input to ECU of controlling an electronic component of vehicles, and enhances a user's convenience.
