I have a ME7.1.1 file that I read from the ECU and me7check claims it fails checksum.  Is this a bad read?  Or a bug?

Yup. Definitely checksum errors. Not sure why you haven't seen any DTCs but perhaps checksum checking is disabled in that file.

You can try correcting the file and writing it back, but if it is working, I don't see a good reason to mess with it.

Well I do have to make some changes.  Coding out SAI/Rear-O2.  So I guess I'll try to correct all of the checksum errors.  Thanks

What does Romsys checksum failure(s) found mean and how can I get rid of it?

My file is 8D0907551K



Just wondering if there has been any update on this checksum error
