Encountering the error message “You need the bench box to continue” when the bench box is already connected to the KT200 can be puzzling. Here’s how to address this issue, even when you’re using the original power adapter with a voltage of 12.8v.

Troubleshooting Steps:

Bench Box Power Connection: It’s important to remember never to connect power directly to the bench box. Instead, utilize the bench box test function.

Jumper Adjustment: A proven solution involves adjusting a specific jumper. Simply move this jumper one pin to the right. This adjustment is known to work 100% of the time and eliminates the need to move the jumper back for other ECUs.

Additional Tip:

If you move from USB 2.0 to USB 3.0 and work, it will work on your ecu maybe yes but bmw edc16c35/31/1 and others you need to move jumper will work whit usb 2.0 whit jumper moved.
