User feedback: used KT200II to read/write Med17.1.27, got message “ERROR SK2 Bench Locked”, shown as the following images.
Advice and solution:
You must first to unlock, With pcmflash you can read the password and write, the first time you read the password then write it down and that’s how the unlock is done, after that you can read and write it with any device, including the KT200II ECU Programmer.
