【Easy to Use】Plug the OBD2 Bluetooth adapter into the OBDII port of your car, start the car engine, enable Bluetooth on your phone or tablet, search for "OBDII" and pair it (pin 1234). Then run the app, make simple settings, and just wait for it to connect to the car's ECU successfully. If you use the same OBD on 2 or more cars, you need to disconnect the Bluetooth and close the app when you finish testing one car, and re-match the Bluetooth when you plug the OBD into another car.
