: For authentic Alientech tools, a momentary drop in your internet connection can prevent the tool from validating the checksum or "waking up" the ECU via the Alientech servers. Troubleshooting Steps Check Your Voltage
Some newer protocol firmwares create a "Virtual Read."
If you run into an "Errore Generico", quickly run through this exact order of operations: the USB and power cables. Double-check your ECU wiring diagram and continuity. Increase power supply voltage slightly to around 13.5V. Extract logs manually to see if a read actually occurred.
