Not connected
Before you connect
- An OBD2 Bluetooth LE (BLE) adapter. It is also sold as “Bluetooth 4.0”.
- Classic Bluetooth and Wi-Fi adapters won't work: the browser cannot talk to them.
- Chrome or Edge on an Android phone or a computer (Windows, Mac or ChromeOS). On iPhone and iPad it does not work in any browser.
The browser's Bluetooth list will open. Pick the adapter: it's usually called OBDII, OBD or similar.
Don't look at the screen while driving. Read the data with the car stopped, or ask a passenger to do it.
Your car's data stays in your browser. It's only sent if you use it in a diagnosis.
