  If the AlienTech Test Equipment K-Suite software does not recognize the tool and the red LED is not lit, check that the tool is correctly connected to your computer with the USB cable supplied. Ensure the USB cable isn't damaged, and try another identical USB cable if possible. Always use the USB cable supplied with the standard kit. Do not use extension cords or other USB cables. Do not use a USB hub; connect the USB cable directly to your computer's USB port. If the problem persists, contact the Technical Support Service.

  If the AlienTech Test Equipment displays the error message: "Micro protection type not supported. It's impossible to work on this ECU", it means you are trying to communicate with an ECU equipped with a protected microprocessor. Use one of the Families dedicated to these types of ECUs, identifiable by the initials “TPROT” in the name.
