Why is communication to the vehicle not established on my GUTMANN mega macs 56 Bike Other?

If communication to the vehicle cannot be established, ensure the correct vehicle is selected by engine code. Adhere strictly to the information and instructions provided. Verify that a 12V voltage supply is ensured via the vehicle at pin 16 of the DT VCI. You may also need to perform a DT VCI plug test.
