OBD2 Scanners for General Motors in 2022 (Reviews & Comparison)

When looking at the best OBD2 scanners, you’ll find a couple of different varieties. There are code readers that come with a handheld device, and there are items like this one, that connect to a computer to help you get more from the software.

There are pros and cons to each option, but we like what this scanner has to offer, especially for GM vehicles.

GM Specific Software

One thing about OBD2 scanners is that they are usually meant as a generic tool for a wide range of makes and models. While that can be helpful if you have one of the top brands, it also means that you’ll have a bunch of codes that you don’t need.

What we like about this model is that it’s designed specifically for GM. This means that you don’t have to worry about compatibility issues or not having the right codes for your car.

Freeze Frame Data

Although the primary purpose of these scanners is to tell you what’s wrong with the engine, sometimes they can also give you a glimpse at the overall performance of your vehicle.

In this case, freeze frame data can provide a snapshot of what’s happening, which can help you diagnose the overall health of your car. While it’s not the same as real-time scanning, it’s better than nothing.

When it comes to software-based scanners, nothing really compares to TOAD. The name stands for Total Onboard Auto Diagnostics, and you’ll see that this unit lives up to its title.

Total Vehicle Compatibility

Although this is a “generic” scanner, meaning that it comes with codes for a variety of makes and models, you’ll be impressed by the fact that you’ll have access to everything that GM offers. Since the software is updated all the time, you’ll never be out of date or have the wrong codes.

ECU Tuning and Performance Enhancing

What sets TOAD apart from other scanners is that you can be more proactive about your diagnostics. By connecting to your car’s onboard computer, you can both monitor and improve its overall performance. Most other scanners do not have this capability.

As we mentioned, you can find scanners that are either handheld code readers or software-based options. This unit from iCarsoft is the former, which makes it both convenient and easy to use.

Compact Handheld Model

The best thing about having a small, lightweight code reader is that you can keep it in your vehicle. Since you don’t have to rely on a laptop to scan your car, it’s much easier to manage your diagnostic capabilities.

Code Reading and Live Data Streaming

With basic scanners, you can simply look up vehicle codes and reset the dash lights. Fortunately, with this system, you can also monitor your car’s health and performance in real-time, which gives you valuable insight into how well it’s operating at any given time.

If you like the idea of having a handheld OBD2 scanner, then Innova is one of the better brands you can buy. This model is one of their top devices, meaning that you can do a lot more than you might think.

Read and Clear All Vehicle Codes

As we mentioned, many newer scanners allow you to check additional systems beyond the engine. Thus, if you want to monitor things like airbags, brakes, and tire pressure, this unit will enable you to do so. Keeping an eye on your car’s health has never been easier.

Large 3.5” LCD Screen

Compared to other handheld devices, this one has a much larger and easier to read screen. Navigating through the menus is simple and efficient, and you can see what the codes mean much more easily.

Our final OBD2 scanner is another handheld model, although this one is designed to provide some additional features that will help you maintain your car more efficiently. Let’s see what it has to offer.

Live Data Playback and Recording

One of the most valuable features of any OBD2 scanner is the ability to monitor your car’s health in real-time. Seeing how the engine and other systems are performing while the vehicle is running can help you diagnose issues long before they show up as dashboard lights.

Location Descriptions

With most code readers, you’ll get a short description of the problem. With this one, however, it will tell you where the issue is located so that you can pinpoint it faster. Rather than having to look up the component’s position in the engine, you’ll see it on screen immediately.
