7 Best OBD2 Bluetooth Adapters in 2018 and Why

After considering dozens of Bluetooth Scanners for this guide, and ultimately selecting 7 for testing, the BlueDriver Scan Tool came out solidly on top. It ticks all the boxes in terms of perfomance, price and compatibility. Other adapters tick these boxes as well, but none hit them all quite as perfectly as the BlueDriver while also selling at a great price for such a professional tool.

On the other side, if you’re a beginner, you might want to try the plug-and-play OBD2 scanners first. Plug-and-play tools are easy to setup even for the first time users. Most of them have only two buttons, which are very handy to use. Their main use is to display trouble codes and reset light problems. One common basic scan tool is the Autel MaxiScan MS300. This maybe all you need if you just want to know the codes and perform basic repair. However, if you’re a little more experienced and want something that does more than just display codes, then go for a bluetooth adapter.

These tiny adapters don’t have any built-in software or display like what the traditional scanners have. Instead, they use a wireless or Bluetooth technology to read OBD2 signals and transmit them to your tablet, computer, smart phone, or other device.

With this option, you have to download an app and connect it to your scan tool. Various OBD2 apps are available for Android and Apple users. Some are paid, while others are free. For instance, the app Torque, which is popular for Android devices, offers a free version (Torque Lite) to let you monitor your car’s systems, as well as read and reset faulty codes. It also offers a paid version (Torque Pro), which supports more vehicles and offers more features, such as view map, graphing, and improved real-time information.

To help you on choosing the best tool for your device and vehicle, we created here a short list of the most popular and loved OBD2 Bluetooth Scan Tools on the market today. Check them out!

Final Thoughts

We know that there’s countless of things that can either go wrong while driving. Sure, some things can happen that are out of our own control; but there are also some things that are largely within our control. And it’s up to us if we want to let those things happen or prevent them.

If you want to ensure your and your family’s safety, you have to strictly follow traffic rules and safety road regulations. It’s also important to know more about your vehicle and educate yourself of what to do in case an emergency happens. Installing a Bluetooth scanner is one of our best recommendations as it helps you detect problems while on the road. While it’s primarily designed for emission regulations, a Bluetooth scan tool can now also be used to identify codes and solve your car’s problem.

What is OBD2?

If you own a car that was built after 1996, chances are it has an OBD2 system installed. All vehicles with a model year equal to or later than 1996 are required to comply with the OBD2 standards mandated by the U.S. Environmental Protection Agency (EPA). But what is OBD2?

On-board Diagnostics 2 (OBD2) is a standard system designed for modern vehicles to allow you monitor your car’s performance and detect potential problems. It’s connected to a signal light, called as a Check Engine Light (or Malfunction Indicator Lamp), which flashes when an issue is detected.

The thing is that the warning light can be confusing, and there’s no way it can tell you what exactly is causing the problem unless you connect it to a scan tool. Mechanics have different scan tools and they can help you pull out the code for you to determine the cause of the problem. But this option is expensive, which could run about $100 or more. The good news is, you now have the option to do-it-yourself the diagnosis. All you need is a little technical knowledge and the right equipment for the task.
