Explanation about what? Google for checksum and you`ll find what is checksum. Each type of ecu has different checksum areas and method for calculating checksum.

Thanks friend, but can I trust Winols when it calculates the checksum, and "if not" how can I check CRC? Is there any checksum calculator for different types of ECU (EDC15, EDC16, EDC 17, ETC.)?

If you have genuine WinOLS you can trust checksums calculated.
Almost all writing tools has own checksum calculators when writing ecu.

Anyway, in case of checksum file fail you can write original file back and car is alive again.
