Check the USB Connection: If use a wired interface, pls confirm that the USB cable is securely connected to your computer. Pls not use USB hubs or extension cables. Check OBD-Il Power: Check if the LED on the interface lights up when connected to the car. If not, the OBD-Il port might not be supplying power.
