Best OBDII scan tools for Ford Mazda Lincoln Mercury 2021: What you’ve never found before

Some of the best Ford scan tools aren’t scan tools at all. An OBD2 adapter paired with a high-performance software like FORScan takes your home diagnostics to the next level. Best of all, they offer more features at a lower price.

Want to learn more? We’ve picked out our 7 favorite tools for diagnosing and customizing the ECU of a Ford vehicle. Whether you want to tune your engine or just find out what’s causing that pesky check engine light, one of these adapters will do the trick.

What Is A Ford Scan Tool?

Ford Scan Tool

In general, a scan tool is any device you use to read the diagnostic information from your vehicle. While all modern vehicles are required to be compliant with OBD2 diagnostics, there are a variety of different protocols they use to convey this information. Ford scan tools are specifically designed to support the protocols employed on Ford, Lincoln, and Mercury vehicles.

Keep in mind there are a lot of different styles of a scan tool. Many hand-held scan tools are only designed to read OBD2 information, specifically the trouble codes (DTCs) produced by your vehicle’s ECU. Even the best car code reader can’t access systems beyond OBD2, so you’ll miss a lot of diagnostic data.

This is the main reason we’ve focused on Ford adapters in our reviews here. Unlike stand-alone code readers, these adapters connect your car to your computer, letting you read the engine using dedicated diagnostic software. That gives you access to more diagnostic information, and often even the choice to program and customize your ECU.

What Is FORScan?

FORScan is the recommended diagnostic and customization software for Fords, and will also work on Lincoln, Mercury, and Mazda vehicles. Paired with the right adapter, it can read and program any engine module. Even better, you don’t need to be a professional to use it, unlike the proprietary software used at dealerships.

The only major negative of FORScan is that you’ll need to have a Windows device to use its full functions. There is a mobile version for Android, but it’s not as extensive as the Windows software. The same goes for versions run on iOS devices through Windows emulators.

Of course, FORScan isn’t the only OBD2 software on the market. It’s the best for Fords, but there are others that will offer almost the same range of functions on Android or iOS. You’ll see those mentioned in the product reviews below.

Why Do I Need A Ford Scan Tool?

In all honesty, a scan tool or adapter is an investment that will pay for itself in no time. Most mechanics charge a fee simply to diagnose your system, on top of whatever you’ll pay for the repair. Considering the problem could be as small as a loose gas cap, that’s money you don’t need to waste.

This is why you should own a Ford diagnostic scanner, even if you don’t plan to make advanced repairs yourself. At the very least it arms you with knowledge so you can avoid getting fleeced at the mechanic. You may even find it empowers you to make more of those small repairs yourself.

I’m delighted with this find and highly recommend it to anyone needing a simple way to download fault codes from their Ford.

OBD1 Diagnostics

If you want the best Ford scan tool for vehicles made from 1982-1995, the Innova 3145 is your answer. Using this tool, you can accurately read and interpret trouble codes from the engine or transmission through the OBD1 system.

Keep in mind OBD1 diagnostics are more limited than those included in OBDII. You won’t be able to view freeze frame or graphical data, for example.

User-Friendly Design

Ease of use is the best thing about the Innova 3145. The numerical digital display clearly shows the code, with no need for counting or guess-work.

  • Reads engine and transmission codes
  • Clear digital display is easy to read and interpret
  • Memory feature stores codes even after it’s turned on
  • Easy to use with instructions for all Ford self-tests

Helpful Custom Dashboards

The OBDwiz software that comes with the OBDLink SX gives you the option to display and graph more than 90 parameters. This includes things like on-screen fuel gauges and fuel economy feedback.

Now keep in mind the OBDLink SX is just designed for OBD diagnostics. It does that beautifully and accurately, but it won’t give you trouble codes from other electronic systems. Keep that in mind if you want a tool to troubleshoot airbag or transmission issues.

Wide Vehicle Compatibility

This check engine light reader isn’t just for Fords. It will work with any OBD2 compliant vehicle, which is pretty much any car on the road made after 1996. That’s good news if you need to scan multiple vehicles, either in your household or in a repair shop.

Know more more about you vehicles operation than you can imagine.

Efficient Diagnosis

The Veepeak FORScan USB OBD2 Adapter connects via USB for stable, fast analysis of your system. It’s able to read nearly every sensor module, including those connected to the airbrakes, tire pressure, and transmission. Along with its thorough OBD2 diagnostics, that makes it the best professional automotive scan tool for Fords.

You’ll also get support for bi-directional and active testing with the Veepeak OBD2 Adapter. That’s a lot more helpful than sensor data when you need to know if a specific valve is opening correctly.

Customization and Service

You can program and customize pretty much any electronic feature on your Ford with the Veepeak OBD2 adapter. This includes disabling that annoying double horn honk, and even next-level programming like IMMO and key fobs.

Built for FORScan

The Veepeak OBD2 Adapter is built specifically to work with the FORScan software. This is both a blessing and a curse. On the positive side, it means you’ll have no issues accessing all of the many in-depth features the FORScan software offers.

On the other hand, though, that makes it less likely to function correctly with other software. This is especially problematic for Android owners since the FORScan software for Android is weaker overall.

  • See sensor data from most modules, including transmission, SRS, and ABS
  • MS-CAN/HS-CAN toggle switch
  • Allows configuration and customization of vehicle features
  • Capable of programming keys
  • Baud rate up to 500 Kbps for faster diagnosis
  • Supports active component tests


  • Not compatible with Apple devices
  • Functions of FORScan limited on Android
  • Not reliably compatible with other OBD2 software

While the OHP WiFi OBD2 Adapter can often also program and customize electronic systems, it’s not the most recommended adapter for this purpose. The WiFi connection can be unreliable, and it won’t allow access to all modules on all vehicles.

Wide Compatibility

One advantage of the OHP OBD2 Adapter is that it works with any Ford car or light truck from 1996 through 2019. Since it uses WiFi to communicate, you can use it with devices running iOS, Android, or Windows operating systems. It’s not limited to FORScan, either. Basically any generic OBD2 software will work with it, including free versions.

  • Communicates with all systems via Wi-Fi

Final Thoughts

When it comes to the adapter, you’re looking for two main things: a reliable connection and compatibility with your vehicle. The functions and features are dictated by the program, not the adapter. Make sure you research both before making your final decision.
