How to connect (important for iPhone)
Don't pair it in your phone's Bluetooth settings. Pair it inside the app instead.

1. Plug the KW901 into your car's OBD2 port, which is usually under the dashboard by the steering wheel.
2. Turn on your phone's Bluetooth.
3. Open an OBD2 app such as OBD Auto Doctor and go to Extras, then Connectivity, then Bluetooth.
4. Under Device, choose "Konnwei" and connect.
5. Go back to the home screen, tap the connect icon in the top right, and wait about 10 seconds.
