Connecting to your car
Connect to your car
With the vehicle stationary, locate the diagnostic socket using the vehicle handbook and connect a compatible adapter. Check that it has power. Select the adapter’s connection type in the app settings; choose the correct Bluetooth device or follow the manufacturer’s Wi-Fi network, address and port instructions.
Start the connection in the app and check its status before interpreting readings. A phone-to-adapter connection does not necessarily mean the vehicle’s control unit is responding. Follow the vehicle instructions for ignition and engine state instead of changing settings at random.
If the connection fails
Check adapter power, the selected device or network and the required Android permissions, in that order. If another app is using the same adapter, end that connection before retrying. If the adapter responds but the vehicle does not, check the conditions specified by the manufacturer.
For support, note the message, when it appears, your app and Android versions and the adapter model. Do not send passwords or personal vehicle identifiers. Do not erase your data and profiles just to retry a connection.
