User feedback: used ECUHELP KT200II to write MG1CS011, got message “ERROR SK2 – Bench Locked”, shown as the following image.
Solution:
This ECU is newer than 2020/06 and locked, so KT200II can’t read/write it.
The solution is to use flex or autotunner, first send them for unlock ecu 250€, after you can do obd via ECUHELP KT200II.
