Issue:
Got IMMO data from Kessy module by VVDI Key Tool Plus, load the file into VVDI2 to get 7 bytes CS, and it prompts “CRC verify error”.
Solution:
Reduce Kessy immo data file size from 2.25KB to 2.00KB.
How to reduce Kessy immo data file size?
As the instruction, data from 0*800 is secured and every time Key Tool Plus will get a different result.
So we save data from 0*800 and delete data below 800 (801*900).
Then read 7 bytes CS code without problem, and we can make a dealer key.
Also, we need to save an original key to avoid corrupting data.
