Troubleshooting Pairing Issues

Ensure your device’s Bluetooth is enabled and discoverable. Put the OBD2 scanner into pairing mode (consult its manual for specific instructions). Select the scanner from the list of available devices on your phone or tablet. Enter the pairing code if prompted (often “0000” or “1234”).

Addressing Compatibility Concerns

Check the scanner and app manufacturer’s websites to ensure compatibility with your vehicle’s make, model, and year. Sometimes, specific apps work better with certain scanners. Consider trying a different OBD2 app.
