Our Recommendations for OBD2 Software
1. TOAD
When it comes to getting the right OBD2 software for your vehicle, you want something that is as comprehensive as possible.
Since many modern cars have proprietary codes and systems that update with each new model, you have to be sure that you have a program that won’t let you down.
Also, it’s not enough to just have OBD2 scanning capabilities. Many new vehicles have ECU computer systems, which allow you to monitor the performance aspects of your car.
Our Rating
Integrated Scan Tool
Since we’re focusing on OBD2 scan software, most of the programs on this list won’t come with their own scanners. TOAD, however, does.
This makes it much easier to get started because you don’t have to worry about finding a scanner that is compatible with the system.
Also, many generic scanners can be less than high-quality, meaning that you may encounter issues when trying to diagnose a problem.
TOAD not only allows you to connect to your vehicle immediately, but it also has a Bluetooth option for wireless monitoring.

One issue with most OBD2 scanners is that they only work with the top makes and models. Thus, if you have a European or Asian vehicle that isn’t covered, you’re out of luck.
TOAD standard for Total Onboard Auto Diagnostics, and it’s not hyperbole. All cars, trucks, and SUVs around the world are included with this system.
To make it even better, you get free updates for life. Other software programs require annual renewals to stay current with codes, but TOAD has you covered forever. You’ll never miss out with this system.
ECU Scanning/Programming
If your car has an ECU system on board, then you can do even more with TOAD. This software allows you to make adjustments to your vehicle’s performance, all from your laptop.- WHAT WE DON'T LIKE
- Pros/cons overview
Overall, TOAD comes with everything you’ll need to diagnose and troubleshoot problems with your car.
It also provides online access to forums where you can find repair manuals for any make and model, as well as connect with mechanics to see what they’ve done.
Simply put, no OBD2 scanning software is as comprehensive as TOAD.

One thing that’s nice about this system is that it will work on both your computer or a mobile device. You can download the software onto your Apple or Android phone and diagnose remotely if necessary.
We highly recommend having this service on your computer as well, though, so you can read data and navigate through menus even faster.

You can monitor the data and see what’s happening in real time, which can help you make adjustments for a cleaner, more fuel-efficient ride.
Wireless Reading
With most OBD2 scanners, you have to be plugged in directly to the car to get a reading. With this system, you can access your vehicle remotely.
Best of all, you can buy a scanner that can stay in the vehicle at all times, enabling you to check up on it whenever you like, even while you’re out in the field.

4. FORScan

One issue that you may come across when using an OBD2 scanner is that you may not have access to the proprietary codes listed by some auto manufacturers.
While most dtc codes are universal, some companies have their own systems, meaning that you need access to them if you want to be sure that you’re diagnosing the right problem.
If you have a Ford, Mazda, Lincoln or Mercury car, then FORscan is the best option for you. If you don’t, then you want to avoid this system because it won’t help with any other brands.
That being said, if you have one of these vehicles, let’s see how it works.
Our Rating
Designed for Ford, Mazda, Lincoln, Mercury Vehicles
Overall, we know that many people have foreign makes and models, such as Honda or Toyota. Even other domestic brands like GM and Dodge are not included, meaning that this tool is severely limited.
However, if you fall into one of these parameters, you will have access to a full list of codes offered by the manufacturer. In this case, FORscan is much better than using a generic scanner that may not have all of these tools.
Mobile Compatible
When it comes to reading and diagnosing a problem, we like convenience. The fact that FORscan has a mobile app means that you can troubleshoot like a champ, even if you’re out on the road.
That being said, don’t monitor your car while you’re driving for safety reasons.
Real-Time Data Streaming
When you have your vehicle in a safe area, you can run a variety of tests that help you get a complete picture of how it’s behaving.- WHAT WE DON'T LIKE
- Pros/cons overview
If you have a Ford, Lincoln, Mercury, or Mazda vehicle, this is the scanning software to get.
Generic scanners may not have all of the codes, and comprehensive units will have a lot of unnecessary stuff to sift through to find the right material. This program is easy to use and install.

Store Info for Fleet Vehicles
Although you may only use it for your personal car, it’s nice to know that it’s built for fleets as well. You can monitor every vehicle in the household, as well as compare cars that you may get over time.
Save all of the data for recall later and set up different accounts so that you get a clear picture of each car you’re working on at any given time.
Run Real-Time Data
Do more than see what’s causing the check engine light to come on. Run tests on your vehicles to see how they’re performing. Use this information to perform maintenance and upgrades as you see fit.
Covers Most Makes and Models
Almost every domestic brand is covered here, as well as most popular foreign models. Although the list isn’t comprehensive, it should cover you with no problems. Also, having fewer brands to sift through can make it easier to find what you need.- WHAT WE DON'T LIKE
