A system for preventing tampering with recorded accumulated running distance data is provided which comprises a first memory, a tampering prevention control unit, and a third memory. The tampering prevention control unit is configured to output an error message if the vehicle serial number data stored in the second memory unit is not equal to the vehicle serial number data stored in the first memory unit and in the third memory unit. The tampering prevention control unit is configured to determine whether the accumulated running distance data stored in the second memory unit is equal to the accumulated running distance data stored in the first memory unit, and if not, the tampering prevention control unit stores the accumulated running distance data stored in the second memory unit to the first memory unit.
