Connecting an ELM327 car scanner to your car is a straightforward process that allows you to access your vehicle’s diagnostic data. This guide will walk you through the steps to connect your scanner and start monitoring your car’s performance.
Understanding the Connection Process
Your car has a diagnostic port, typically located under the dashboard on the driver’s side. This port, known as the OBD-II (On-Board Diagnostics) port, is where you’ll connect your ELM327 scanner. The scanner then communicates with your car’s computer (ECU) and transmits data wirelessly to your smartphone or tablet via Bluetooth or Wi-Fi.

-
Locate your car’s OBD-II port: It’s usually under the dashboard on the driver’s side, but its location can vary depending on the car model. Consult your owner’s manual if you can’t find it.
-
Plug the ELM327 scanner into the OBD-II port: Ensure it’s firmly connected.
-
Turn on your car’s ignition: You don’t need to start the engine, but the ignition needs to be on to power the OBD-II port.
-
Enable Bluetooth or Wi-Fi on your smartphone/tablet: Depending on your ELM327 model.
-
Pair your device with the ELM327 scanner: Open your Bluetooth settings and search for available devices. Your scanner should appear as “OBDII,” “ELM327,” or a similar name. Select it to pair. If your scanner uses Wi-Fi, connect to its network according to the manufacturer’s instructions.
-
Launch a compatible car scanner app: Apps like Car Scanner ELM OBD2 are available for both Android and iOS.

Connect to the ELM327 within the app: The app will guide you through the final connection steps.
Choosing the Right ELM327 Adapter
While many ELM327 adapters are available, quality can vary. Cheap clones often have connectivity issues and can even negatively impact your car’s performance. We recommend using genuine ELM327 adapters or reputable brands such as Kiwi 3, Viecar, V-Gate, Carista, LELink, or Veepeak. Avoid adapters marked as version 2.1, as they are known to have bugs.
Troubleshooting Connection Problems
If you encounter difficulties connecting, try the following:
- Ensure your adapter is fully inserted into the OBD-II port.
- Double-check your Bluetooth or Wi-Fi connection.
- Try restarting your smartphone/tablet and the car.
- Consult the app’s troubleshooting guide or contact the developer for assistance.
Accessing Your Car’s Data
Once connected, you can use the app to read and clear diagnostic trouble codes (DTCs), monitor engine performance, view sensor data, and much more. This information can help you understand your car’s health, diagnose problems, and potentially save on repair costs.
Conclusion
Connecting a car scanner ELM to your car opens up a world of information about your vehicle’s performance and health. By following these steps and choosing a reliable adapter, you can easily tap into your car’s diagnostics and take control of your car maintenance.
