When your vehicle is running rough or if the check engine light comes on, your first thought may be to make an appointment at your local auto shop so you can get the problem fixed. Having an OBD2 (Onboard Diagnostics-2) scanner creates an alternate scenario where, instead of looking elsewhere for help, you can rely on the scan tool to understand what’s wrong with your car. You can take the appropriate steps to fix the problem and then use the scanner to clear the error code. 

Bluetooth technology makes these car scanners much more user-friendly. The scanner can transmit data wirelessly to your laptop, tablet, or smartphone. Therefore, you can leave the scanner plugged in and diagnose issues even when you’re on the road. The best part is that you don’t have to be an automotive expert to use these tools. Most of the models can be used by the average car owner — instead of giving a technical description, they describe the severity of the issue and highlight consequences if you continue to drive. So if you‘re looking for one of these handy devices, then you came to the right place.

The Best OBD2 Bluetooth Scanners

Built for both DIYers and professionals in mind, the Innova 5210 Bluetooth CarScan is an entry-level OBD2 diagnostic tool that diagnoses trouble codes and lets you know how to fix them. With this scan tool, you don’t have to worry about coming up short when diagnosing check engine warnings, ABS brakes, emission levels, battery, and charging systems. Plus, it has a 2.8-inch color display that shows more than 20 pieces of real-time data such as speed, RPM, and oil temperature.

The unit also features freeze-frame data, which is like a snapshot that displays all vital information on your car’s overall health from when a trouble code is triggered. It’s designed with both Bluetooth and Wi-Fi technology so you can gain access to Innova’s cloud-based databases or vehicle-manufacturer data. Therefore, you can access verified fixes from professional technicians and apply them to your vehicle. Also, you can pair it with RepairSolutions2, which is a free mobile app that gives a comprehensive diagnosis and suggests fixes. Having fixed the problem, this scan tool lets you clear engine trouble codes. Plus, it supports English, French, and Spanish.

Best OBD2 Bluetooth Scanners Buying Guide

At one time, OBD2 scanning technology was only available to professional automotive mechanics. You had to spend time and money dragging your vehicle down to the repair shop to check the state of your car whenever a trouble code came up and you had no idea how to clear it.  In today’s world, Bluetooth or wireless OBD2 scanners have made things easier for drivers — you can diagnose and fix problems in the comfort of your garage. You can also rely on your smartphone or laptop to gain more information on the trouble codes that come up through mobile apps tailored for your OBD2 scanner. However, you shouldn’t just buy any Bluetooth scanner on the market. First, read our buying guide for an in-depth analysis of OBD2 Bluetooth scanners so you can know what to look for.

Do You Need an OBD2 Bluetooth Scanner?

Do You Need an OBD2 Bluetooth Scanner? 

A Bluetooth scanner can help you better understand your vehicle’s systems since the data processing is fast and you can get real-time data in no time. Plus, they can easily connect to Android, iOS, and Windows devices so it takes away the hassle of having to deal with wires. Additionally, vehicles manufactured from 1996 and beyond have OBD-II ports. Therefore, a wireless OBD2 scanner becomes a vital tool for a professional mechanic — you can buy one wireless scanner and use it on multiple vehicles. Also, if you have an older vehicle, you can benefit from having an OBD2 Bluetooth scanner since it can help you test your emissions before you have to take the smog check. If your emissions are beyond the recommended level, you can remedy the situation and get your vehicle in tip-top shape in good time. Here are a few more benefits:
  • Save yourself costly trips to the mechanic every time the check engine light comes on.  
  • Some models can correct anomalies by sending commands to the specific car system. 
  • It lets you troubleshoot a wide range of issues with your vehicle. 
  • It helps you learn more about your car’s systems and components.

Different Kinds of OBD2 Bluetooth Scanners

There are two significant OBD2 scanner types that you should be aware of before buying one.

Code Readers

A code reader is a no-frills device that only reads and clears trouble codes. It provides an easy and quick way of diagnosing what’s wrong with your car. Anyone can use a code reader, as it gives a brief and non-technical description of the problem. However, since the information provided is minimal, you have to do more research by looking up the code and possible fixes.  These devices are cost-effective, but the trade-off is that they can’t access all types of data from your vehicle. For example, a few models may not have access to the ABS brake system or airbag control unit.

Professional-Grade Scan Tools

Professional-grade scan tools are designed to provide more comprehensive data than code readers. They not only display the meaning of error codes, but can also record the data and provide access to a large database where you can get solutions to fix the problem. Also, scan tools can read both generic and manufacturer-specific codes.  Furthermore, these scan tools let you monitor your car systems in real-time. Some models have a few self-correct functions so they can resolve a few issues with your vehicle even without you having to do anything. 

The Most Important Features of OBD2 Bluetooth Scanners

Many key factors must be considered when trying to get the best OBD2 scanner. Even if you have used these scanners before, it helps to brush up on your knowledge of the different technical aspects of these devices.

Vehicle & App Compatibility

While most OBD2 scanners have a standardized system that’s compatible with popular car brands such as Toyota, Honda, Chevrolet, and Ford, it’s prudent to ensure that the scanner is compatible with your vehicle. Hybrid, electric, and foreign vehicles are often left out of the compatibility list so if you have any of these vehicles, you may want to dig deeper and find a scanner that’s designed for your vehicle.  Another thing to note is the app compatibility. While a majority of these scanning tools come with companion apps such as the BlueDriver app, there are a few options that only work with third-party apps such as Torque, OBD Car Doctor Pro, or OBDLink. Prioritize devices that come with companion apps since it gives you total control of the scanner and a complete program of diagnostic options. 

Live Data Scanning 

Receiving accurate live data on your vehicle’s systems can be a helpful way of getting vital information on your vehicle’s performance. It lets you understand how well your car is doing and you can use the information to come up with a maintenance schedule. You can also use live data to pinpoint a few car issues such as why your vehicle isn’t fuel-efficient.  Ideally, you should choose a scanning tool that gives a detailed analysis of how your vehicle is operating with graphical representations that are easy to interpret. A device that can store the recorded data for future reference is also a bonus. 


Before you purchase any Bluetooth scanner, you have to look into the number of functions it provides to tell if it’s worth the money. Scanners that offer more functions beyond basic diagnostic trouble code reading and clearing are usually more expensive. If you are a professional mechanic, then you need a more advanced unit that lets you read other controls like the transmission, airbag unit, ABS brakes, and more.  Also, many vehicle manufacturers include specific trouble codes that can only be read with an advanced scanner. The more affordable, entry-level scanners can only read generic trouble codes, so you have to consider spending more money if you would like to access more information from your vehicle. 

Best OBD2 Bluetooth Scanner FAQs

From the above buying guide, it’s clear that there’s a lot to consider in terms of features and functions when it comes to purchasing the right diagnostics tool for your vehicle. If you still aren’t confident about picking the right OBD2 Bluetooth scanner, read some of the answers we have provided to a few common questions asked by buyers to gain deeper insight into the topic. 

Q: What kind of problems can an OBD2 scanner diagnose?

Besides check engine light codes, the latest OBD2 scanners can diagnose a variety of trouble codes, including ones triggered by oxygen sensors, airflow circuits, camshaft misalignment, airbags, oil pressure, intake and exhaust valves, and more. 

Q: Will an OBD2 Bluetooth scanner drain my car’s battery?

Some scanning tools will drain the battery after you turn off the engine. To be on the safe side, unplug the scanner every time you shut down your vehicle. 

Q: How can I tell that my vehicle is OBD2 supported? 

If your vehicle was manufactured in 1996 or later, then it’s most likely OBD2-compliant. You can locate the OBD2 port on the dashboard beneath the steering wheel column. 

Q: Is an OBD-II Bluetooth scanner safe for my car?

OBD-II scanners can run multiple system-specific tests and programs on your vehicle without causing any sort of damage, even when left plugged in. The only threat it may have to your vehicle is draining the battery when left plugged in and the engine is switched off.
