If you have a problem read ID or read eeprom of 59F with KT200, check the following:
1. Check your hardware version
2. Make sure the correct plug you are pinned into. Sometimes users made wrong pin. Pin is on other plug, rotate ecu on 180 degree.
3. Restart computer, repin ECU, make sure MFC is connected tightly and try again, otherwise suspect ECU.
