Step 1: Find the OBD2 Port

The OBD2 port, also known as the Diagnostic Link Connector, is easily accessible. It is located on the driver’s side dashboard. It is located on the left side of the dashboard, just below the steering column.

This port is usually covered by something resembling a flap.

Step 2: Connect the OBD2 Scanner to the Port.

Once you’ve located the OBD2 port, simply insert the Bluetooth scanner into it. Make sure you plug it in properly by gently pushing it inside, or else the Scanner will not receive any signals.

Step 3: Start Your Engine or Leave Your Car Idling

Read your Scanner’s user manual to determine whether you must start your car or keep it in idle mode when using the Scanner. This will differ depending on the scanner’s brand. Make sure you follow the correct procedure; if you keep the car in idle mode when the Scanner requires it to be in idle mode, or vice versa, the tool may be damaged.

Step 4: Download the Scanner App and connect it to your phone.

After connecting the OBD2 Scanner and it begins receiving the signal, launch the Scanner application on your phone. You should be able to tell which application you need to install on your phone by reading the user manual, as it varies depending on the brand.

Install the scanner app and enable Bluetooth on your phone. Don’t worry, the app for connecting your phone to the Scanner should be compatible with both iOS and Android devices.

When you open the app on your phone, you should see a ‘connect’ button. After you click that, you must wait a few seconds for the connection with the OBD2 Scanner to be established.

Step 5: Use the App to Run the Scan

You will be able to run OBD2 scans from your phone once the connection has been established. Each application’s user interface will be slightly different, but they will all be very simple, making navigating through the app a breeze.

Step 6: Determine the Meaning of the OBD Error Codes

Following the completion of the scan, OBD2 error codes will be displayed on your phone, and you must understand what they mean in order to proceed with the diagnosis of any issues. Error codes begin with one of four letters: P, B, C, or U, indicating problems in various parts of the car.


The Bluetooth OBD2 is an almost flawless tool that provides utility that no other scanning tool can match. As you can see from our article on how to use the OBD2 Bluetooth scanner, it’s a very user-friendly tool that only takes a few minutes to set up.
