Hello,
i have read the ecu with Kess through OBD and i wrote the backup back into the ecu. The ECU it isn't recognized anymore.
I found this fix:
ECU remain in programming mode.
1. Read IROM / XROM and EEPROM in bootloader mode.
2. Fix IROM/XROM using bootloader readout and OBD ORI readout (you will probably need to paste part of map zone and chk/RSA zone)
3. Write fixed IROM/XROM by bootloader (do not touch EEPROM!)
4. connect ECU to the car and write repaired IROM/XROM (same used for bootloader) by OBD.
It will automaticaly fix eeprom problem.
So i made a boot mode with Galetto and read the flash and once more. I compared the IROM that i read from obd and IROM from boot mode. And i Fixed the file, put it back in with Galetto (boot mode) and the ecu is now again recognized - but the car doesn't start. I also flashed the ecu once more with OBD (Step 4.) with the repaired file but then the Car isnt recognized anymore. Is the problem in EEPROM? - If yes, how can i fix it? Did i make a good IROM fix? Please, if someone could help. In attachment i send you all the files(OBD Backup, BOOT Mode Backup, My FIX, EEPROM Backup).
Here is the ECU data:
03L906022MC 9979
1037564342
Thanks!
