Feedback: I am using KT200 to read and write Citroen EDC17C60 TC1793, I changed the internet connection from different devices and it always gives the same error when trying checksum correction. Use also 13.5 volt and no 12.4! Please help me.
Possible reason and solution:
If you read the file from this ECU, do manual checksum correction with Winols or Lsuite, and write a file without checksum correction, and it will be okay. If it’s file from another ecu.. first correct trpot.
