Click “Erase” to clear the external ECU.
8.Click “Personalization” and select the original Car EEPROM Data to write
Click “OK” once personalization is successful.
9.After that, click “Read TCU Information” again to confirm if the ECU data has been successfully erased.
10.Finally, install the ECU back into the vehicle, and complete the programming and coding process.
