I use IM508 + XP400 Pro Combination. I am gonna try to read XET512 Chip D-Flash Data to delete the crash data from my airbag module (ACSM4 65.77 - 9280186-01 has XET512VAL Chip). I tried the Programmer Software and Autel IM508. But when I try to read D-Flash Data it asks to write partition first but when I try to write, it is warning as "Write Partition erases D-Flash and EEE Data". How can I get this D-Flash without erasing it. There is a tool which is your competeter VVDI reads this data I think. I saw people share the D-Flash Datas which they reach out via this tool and they share in the forums. I believe that XP400 Pro also should have it somehow. How can I get D-Flash Data before erase it ?
