How to Use a Bluetooth OBD2 Scanner

Locate your car’s OBD2 port and plug in your scanner. It will be somewhere within reach of the driver’s seat. Often it’s located in the lower dash, to the side of your steering wheel, but some cars have the port located in the center console or in a storage cubby.

Turn your ignition to the “on” position, where your accessories and dash are powered. Do not start your car.

From your Android device, smartphone or tablet, go to your settings and then to your Bluetooth settings. Turn on your phone’s Bluetooth, and then scan for nearby devices.

Some scanners may require key code or PIN, which will be included in your device’s documentation. For many, the default PIN is 1234, 12345, or 0000. Some OBD2 Bluetooth scanners, such as the OBDLink MX Bluetooth discussed above, use a physical button on the device itself to pair with your phone instead of a PIN.

Open your preferred OBD2 app. Go to the Settings page and pair the app to your Bluetooth scanner. Make sure it’s connected, and you should be good to go. Check your chosen app ‘Read Me’ file or FAQs in the Google Play or Apple Store for help with the app itself.

If you have trouble with Bluetooth pairing, try these tips.

Unpair any previously used Bluetooth devices, such as a headset or speaker.
Make sure the app is not running in the background and close the app before pairing your device to your phone.

And do try the classic fix: turn off the Bluetooth, turn it back on again, and try rescanning for the device.

Finally, check the website of the manufacturer of your device. Often there are some manufacturer tips or a firmware upgrade available that will clear up any connection issues you may have.

Understanding Your Bluetooth OBD2 Scanner’s Codes

Most commonly, the trouble codes you’ll see are P0xxx codes. These are universal codes common to all cars.

Keep in mind that just knowing what the code means doesn’t always suggest an immediate fix. Codes can have multiple causes!

Many OBD2 apps have diagnostic help built into the app or include access to online databases of suggested fixes. If yours doesn’t, you’ll want to consult owner forums for your year, make, and model of car, or consult a repair manual, such as those published by Haynes, Chilton, or Bentley, to research the possible causes of the code your car is presenting.

Remember: when attempting a repair, for your sanity, start with the simplest and cheapest possible fix and then escalate to more complex possibilities!

Your Bluetooth scanner will throw anything your car makes available to the OBD2 port to your phone. This means it’s limited by what your car’s manufacturer has decided to make available to be read through the OBD2 port.

Be aware that not all cars deliver all information from every sensor to the OBD2 port. The information available to you is also somewhat dependent on the app you’ve chosen to read the information coming off your Bluetooth OBD2 scanner.

Many of the OBD2 scanner apps are free, but a purchased app may be a better choice for you as some of the more pro-level apps or apps developed to work best with a particular Bluetooth OBD2 device offer a better interface or make more information available to you.

Also important to know: the amount of information coming through your Bluetooth scanner may slow down the refresh rate on your app.

Faster devices can “throw” more information to your phone at once and will display updates on your app more frequently. This is especially important to be aware of if you’re using a Bluetooth OBD2 scanner for live updates or real-time monitoring of your car’s systems.

Resources to Find the Codes and How to Interpret Them.

The app you’re using with your OBD2 scanner likely has repair help built right into it. But if it doesn’t, try some of our suggested options.

Many different sites offer code lookup, often including the app you’re using with your Bluetooth scanner, but two websites we’ve found helpful are and

Other useful resources are any make-specific online forums or Facebook groups that may exist for your specific car. You can often find these with a Google or Facebook search such as, “Dodge Challenger owner forums.”

And finally, check any repair manual or factory service manual you may have on hand for your car. Published in paper or online, these often have suggested fixes for common trouble codes.


We hope we’ve provided you with some solid help sorting through the range of Bluetooth OBD2 scanners available.

Now you’re well-prepared to keep your car on the road for many happy years of motoring, and with a dongle in your toolbox, you’ll be ready to help out a friend or family member when they run into car problems as well.
