The OBD2 port is also known as the Diagnostic Link Connector and is straightforward to find. It is on the underside of the driver’s side dashboard. To be exact, it is on the left side of the dashboard and right below the steering column.

Most of the time, this port will be covered with something like a flap.

Step 2: Insert the OBD2 Scanner into the Port

Once you have found the OBD2 port, you will just have to plug the Bluetooth scanner into the port. Make sure you plug it in properly by pushing it inside with slight pressure, or else the Scanner will not be receiving any signals.

Step 3: Start Your Engine or Keep Your Car in Idle Mode

Read the user manual of your Scanner to find out whether you have to start your car on or keep it in idle mode when using the Scanner. This will vary depending on the brand of the Scanner. Make sure you take the proper step; if you keep the car in idle mode whereas the Scanner calls for it to be in idle mode or vice versa, the tool may get damaged.

Step 4: Download the App for the Scanner, and Connect it To your Phone

After you have connected the OBD2 Scanner and it starts receiving the signal, you need to open the application of the Scanner on your phone. By reading the user manual, you should be able to tell which application you have to install on your phone since it varies depending on the brand.

Install the scanner app, and turn on your phone’s Bluetooth. The application for connecting your phone with the Scanner should be compatible with both iOS and Android devices, so don’t worry.


Open the application on your phone, and you should see a button that says ‘connect.’ After you click on that, you will have to wait a few seconds, and then the connection with the OBD2 Scanner should be established.

Step 5: Run the Scan Using the App

After the connection has been established, you will be able to run the OBD2 scans from your phone. Each application’s user interface will be slightly different, but all of them will be very simple, so navigating through the app will be a breeze.

Step 6: Learn What the OBD Error Codes Mean

Upon completing the scan, OBD2 error codes will be displayed on your phone, and you need to know what they mean to diagnose any issues. Error codes begin with one of four letters P, B, C, or U, each indicating issues in different parts of the car.

A P at the start of the code means there’s a problem with the powertrain, B for Body, C for Chasis, and U means undefined.
