Buying Guide On The Best professional automotive diagnostic scanner

If you are an average car owner that likes to get insight into your vehicle’s problems before taking it to a dealership or mechanic, you need to choose the tool that will help you achieve that and more. Here are some of the factors to consider so that you can choose the right code reader for your car:

Type of Vehicle diagnostic tool

Every OBD scanner falls into one of two main categories, namely diagnostic scan tools and adapters. Diagnostic scan tools are the traditional scanners.

They are stand-alone devices that connect to the OBD port using an OBD connector.

On the other hand, adapters are diagnostic dongles that work with a mobile device.

The dongle plugs to the OBD port and then transmits diagnostic data to a smartphone or tablet via Wi-Fi or Bluetooth.

You need to install a diagnostic app before using an OBD dongle.

Adapters are usually small and can be left plugged in. It makes more sense to buy one of these if you want a device that can do real-time vehicle monitoring.

But most of them are not as durable as traditional scan tools. Plus some apps require paid subscriptions to use.

Diagnostic scan tools are a lot simpler to use than dongles. They feature a straightforward menu. However, they are more expensive compared to dongles.

So, ultimately your choice here not only depends on your budget but also if you’re comfortable using one over the other.

Vehicle compatibility

This is undoubtedly the most important consideration. Make sure the scanner you pick actually works on your vehicle.

Manufacturers usually list all the vehicle makes and models that are covered by a particular scanner. Be sure to check that out on their website or from customer reviews.

You may want to know that while some scan tools are designed to cover just one or two vehicle brands, others are universal and work with a wide variety of cars.

For example, while the Foxwell NT510 covers BMW, Rolls-Royce & Mini, the Ancel AD410 works on all OBD2 cars.

Also noteworthy is that there are scan tools for OBD2 cars, others for OBD1 cars and still some that cover both OBD1 and OBD2 vehicles.

So before settling on one make sure it covers the type, make and model of your car.

Auto Diagnostic Functional features

At the very least a diagnostic scan tool will display engine error codes.

You’re guaranteed to read (and clear) codes related to the Check Engine Light, as well as run emission tests even with the most basic device.

However, some more complex scanners allow you to get more detailed diagnostic information.

You can do such tests as BMS, EPB, oil reset, SRS, DPF, TPMS etc. Others support programming, relearning and actuation.

Before making the purchase you may want to list down all the must-have features. That way you will know exactly what you want your device to be able to do.


Unless you are buying a diagnostic scan tool for a professional auto shop, most of these devices will not cost you an arm and a leg.

They typically cost anywhere from $50 to thousands of dollars. It all depends on the features that it brings to the table.

With that said, make sure the one you settle for is within your budget. It may sound obvious but you can’t purchase something that you don’t have the money for.


A diagnostic scan tool won’t help you in any way if you can’t figure out how to use it. Virtually all of them come with a user manual to help you find your way around the menus.

That said, start by reading customer reviews to ensure that it doesn’t have complicated menus. And that the accompanying user manual can actually help.


Not all OBD scanners are created equal. Some brands are known for their high-quality functionality and durability. Conversely, others are popular for all the wrong reasons.

With that in mind, you may be able to tell whether your device is good or not just by looking at the brand.

Some of the best car diagnostic tool include Innova, Autel, Launch Tech, Foxwell, Actron, BlueDriver,  and Ancel.


OBD scanners need to be upgradable in order to accommodate the latest diagnostic technology and newer vehicle models.

If you buy one that doesn’t upgrade it will be obsolete the moment you buy a newer car.

In short, check to know whether its software is upgradable, how easy it is to update and if the updates are free or not.

Important Tips On the Best professional automotive diagnostic scanner

When buying a scan tool, there are a few things you should take into consideration so you can enjoy your tool to the fullest. Here are some of the most important ones:

Choosing A Scan Tool

Now that it is relatively easy for the average vehicle owner to get a diagnostic tool, choosing the right one is particularly essential. To ensure you are buying a quality device, you should consider only reputable brands that are well known for producing quality tools.

You also need to confirm if the code reader can receive updates in the future so that you take advantage of new manufacturer fixes and the addition of newer vehicle models.

If you are looking for basic diagnostic functions like reading and clearing vehicle error codes, you can go for cheaper models instead of the advanced models. This will help you save money without compromising performance.

Checking OBD Compliance

This is particularly important if your car is produced after 1996 as this is a requirement of the United States regulation. This will equally make it easy to work with the manufacturer’s specific trouble codes and other testing and diagnostic codes.

Know The Difference Between OBD I Vs OBD II

All cars that are produced before 1996 – before the advent of computerized controls – generally fall under the OBD I category. Majority of the vehicles introduced after 1996 are considered to be OBD II compliant.

It’s also essential that you only choose the code reader that is compatible with the model, make, and year of your vehicle. Therefore, understanding the difference between OBD I and OBD II vehicles helps make it easy to choose the right scan tool

Understand The Features Of Scan Tools

No scan tool is completely the same as another. This is because of the difference in functions and features on each model. For example, some car diagnostic tools provide freeze data, SRS and ABS functionality, a large database of verified fixes, real-time data, etc., while others lack these features. In most cases though, you get what you pay for.

So if you are planning to use your diagnostic tool for a variety of functions, consider the features on the tool before purchasing.

Bottom Line

The takeaway point is that there are so many auto diagnostic tools out there.

However, not all of them have the same features and compatibility. With this review, you can know whether a particular device works on your vehicle and if it has the features you need.

We only took the best professional car diagnostic tools. So no matter their few flaws, each one has something solid to offer.
