<p>Disclosed is a vehicle data abnormality determination device, which provides a storage unit that stores two-byte remainder terms, which are the result of CRC calculations of areas being calculated, in a predetermined memory area, and an arithmetic logic unit that calculates CRCs including the two-byte remainder terms, and calculates CRCs including the two-byte remainder terms following the CRC calculations of the relevant areas when performing CRC calculations so that the calculation results are always zero when data has not been manipulated. Said vehicle data abnormality determination device can easily and adeptly detect whether data has been manipulated.</p> |
