What It Is / How It Works

This is a Bluetooth OBD2 scan tool that plugs into your vehicle's diagnostic port and pairs with the MAXOBD mobile app on iOS or Android. It reads and clears fault codes across major systems like the engine, airbag, transmission, ABS, and more, and is compatible with most OBD2 vehicles from 1996 onward.

Who It's For / Use Cases

OBD2 scan tools suit DIY car owners who want to understand warning lights before visiting a shop, as well as hobbyists who enjoy monitoring live sensor data. They also help small workshops and mobile mechanics perform quick diagnostics without a full professional scanner.

How to Use / Care

1. Locate your vehicle's OBD2 port, usually under the dashboard near the steering column.
2. Plug the scan tool into the port; the device powers on through the connection.
3. Pair the tool with your smartphone via Bluetooth and open the MAXOBD app.
4. Follow the app prompts to read or clear fault codes and view live data.

How to Choose

When choosing an OBD2 scan tool, consider the systems it covers—basic tools read engine codes only, while full-system models handle airbag, ABS, and transmission. Check wireless connectivity and app compatibility with your phone.
