Car Diagnostic Tool Buying Guide
The number of different car diagnostic tools that are available to buy is increasing every month. The market is fairly saturated with many OBD2 scanners under $100 being the most popular for the average car owner or home mechanic.
However, there are many people that are professional mechanics or enthusiasts and wish to purchase a premium car diagnostic tool. Equipped with a more capable car scanner, you will be able to do far more than just read and clear codes but also perform modifications, real time tests and much more.
At ProCarReviews, we have been testing OBD2 scanners for many years and currently have over 50 within our garage. To help you make an informed buying decision, we have produced the below guide regarding car diagnostic tools.
Types of Diagnostic Scan Tools
OBD2 scanners come in a range of types with the larger and more powerful being suitable for professionals or enthusiasts. This is because they often come with a larger processor, hard drive and other features. The smaller devices are the cheapest and perform the basic tasks such as reading and clearing error codes.
Depending on the age of your car will be a major factor in which car diagnostic tool is best. Modern cars will have an OBD2 port but vehicles that are made before 1998 (before they were standardized) may have an OBD1 port. Therefore, you may need to purchase an adapter to convert the OBD2 connection to an OBD1.
The term OBD stands for “On Board Diagnostics” and the number “2” refers to the second generation, which is a huge improvement upon the first generation. The OBD1 scan tools aren’t universal and are usually specific to each car and provide completely different codes.
The introduction of OBD2 technology is a huge improvement and the amount of information you can get from a from a scanner is much higher than OBD1 tools. The below image is an example of a OBD2 connection that you will plug in to a port.
OBD2 compatible vehicles can connect to a range of diagnostic tools and provide standardized error codes, which makes researching the issue much easier. However, it’s always worth spending that little bit extra for additional functionality as you may need it one day.
Ease of Use
Older car diagnostic tools are notoriously difficult to use with bland interfaces, poor usability and various wired connections. However, with the advancements of technology, they have become just as easy to use as a smartphone.
For those that have never used a scan tool before, there are thousands of videos on YouTube with mechanics providing detailed tutorial videos. However, these days most brands will provide detailed instructions in the box or online.
Of course, if you are new to using a car diagnostic tool, we highly recommend avoiding the professional devices. These may provide far more details than necessary and you may only want to find out the error code that’s stored on your car’s ECU.
We have trialed many of these OBD2 scanner tools within this article but the BlueDriver really excelled in the ease of use category. Once it has been connected (as shown in the image below), you simply go to the app and perform various checks. You could even leave the BlueDriver connected whilst you are driving and use the application as your very own car HUD to display various real time data.
Why You Need a Car Diagnostic Tool
Owning a scan tool is very helpful when trying to diagnose issues with your car. All you have to do is connect the scanner into the port and you are on your way. It avoids the guesswork and potential to spend thousands on parts and labor.
Scan tools automatically read and analyze the vehicle to provide a detailed list about the car and any codes that are stored. With a wide range of possibilities to choose from, anyone is able to perform various diagnostic tasks. The main advantages of owning a diagnostic scan tool are:
- Check to see if your car is safe to drive and wont cause any damage
- Save you money as you will not need to use a mechanics
- Most recent data and stored codes
- Scan vehicles before you buy them
- Add/Modify current features i.e. full window closure

Other Factors To Consider
The amount of car diagnostic tool devices out there will continue to increase but you will want to keep an eye out for their features. From the on screen information to the data storage, these factors can make the difference between an easy to use or terrible scan tool.
If you are opting for a device that runs from an application, we highly recommend checking reviews of the smartphone application. This will give you a strong indication to whether it is compatible with your phone and features work as they should.
We highly recommend sticking to the big brands such as Autel, Launch, Ancel, Actron, Innova, Foxwell and a few others. This will give you complete peace of mind that it won’t cause any damage to your ECU and function as you would expect.
