5 Best Subaru Scan Tools Review 2020

The best Subaru scan tool can save you a trip to the mechanic by identifying what’s turning on your check engine light from the comfort of your home garage. Not only does this save you money in the long run, it gives you peace of mind that your vehicle is running like it should. 

Some scan tools are all-purpose, designed to work with any vehicle. The advantage of a Subaru scan tool is that it’s built to work with your vehicle. This makes it more likely to support your car’s specific protocols and systems. In addition, these scan tools save you some money, since more comprehensive professional options tend to cost hundreds of dollars.

There are two main design formats for Subaru scan tools. Hand-held scanners have the diagnostic software built right in. You interact with your vehicle using the provided screen. This is convenient for anywhere diagnosis, even when you’re outside of WiFi range.

The other option is an OBD2 adapter. These devices only communicate with your engine, and don’t provide the user interface for you. Instead, you’ll need to download diagnostic software on your phone or tablet. The main advantage of this is these adapters give you more functions for less money. On the other hand, you’ll need a WiFi connection to use them, and you have to do the legwork to get your own app. 

For Subarus, you can find both hand-held scanners and wireless adapters built to work perfectly with the manufacturer’s protocols and systems. We’ve picked out our 5 favorite Subaru scan tools and reviewed them below. Check out the comparison to find the one that meets your needs.

BAFX OBD2 Scanner is a wireless adapter that turns your iOS device into a powerful diagnostic tool.

Similar to the FIXD™ above, BAFX OBD2 Scanner is a wireless adapter that turns your iOS device into a powerful diagnostic tool. Unlike FIXD™, BAFX doesn’t come with its own software. Instead, you’ll need to choose your own app. This is an advantage for some, since you can pick the option you like best, but it also adds an extra step (and, often, extra costs).

BAFX OBD2 scanner based on your application.
BAFX OBD2 scanner depends on your app.

How easy the BAFX OBD2 scanner is to use from a navigation standpoint will depend on your app. Physically, all you have to do is plug it in and pair it to your device. Its data processing rate is pretty fast, and it supports real-time data tracking and graphing.

For OBD2, BAFX is comprehensive. You can check on-board monitors, see emissions data, and read or clear any codes your ECU has triggered. For diagnosis, it works best with OBDFusion, Torque, and FORScan. With other apps, you’ll want to check their functions and compatibility, but it’s usually reliable.

The only major drawback of BAFX is that it doesn’t go beyond OBD2. Some users report being able to read transmission codes with it, but you shouldn’t count on it to do that for all vehicles. Still, it’s the best scan tool for Subaru if you want an affordable way to turn off your check engine light

Pros

  • Great value
  • Can access all OBD2 modes, including Mode 6
  • Compatible with a wide range of diagnostic apps
  • Works with all OBD2-compliant vehicles
  • Fast data processing rate
  • Reliable connection with all OBD2 protocols

The Foseal OBD2 Scanner is even more affordable than the BAFX scanner above. It’s also compatible with a lot of diagnostic apps, including some free ones, so you can diagnose your vehicle for less. Even better, it can work with any device, whether your operating system is Windows, iOS, or Android. 

We like the real-time sensor data functions of the Foseal OBD2 scanner. You can quickly and easily check the fuel trim data, coolant temperature, RPMs, and more. As far as code reading, it can read and clear permanent and pending codes as well as active DTCs.

You can use the Foseal OBD2 Scanner with most OBD2 compliant vehicles, which includes all Subarus made after 1996. The only exception to this is that it won’t work with many diesel engines, so you’ll want to check with Foseal first before buying it for a diesel Forester or Outback. 

As you might expect for the price, the functions of the Foseal OBD2 Scanner are limited. It’s great for checking your emissions or clearing the check engine light, but don’t expect it to work for enhanced diagnostics. Still, it’s well-built, connects reliably, and is a great option for Subaru owners who want basic OBD2 diagnostics. 

Pros

  • Wide functionality for live data tracking
  • Read and clear all engine DTCs
  • Supports emission testing and I/M readiness
  • Works with Windows, Android, and iOS devices
  • Compatible with most diagnostic apps
  • Lowest cost

Final Thoughts

Any one of these scan tools will reliably work with the majority of Subarus (with the non-diesel exception of the Foseal OBD2 scanner). The only compatibility you’ll have to worry about is which kind of device you use if you want to go the wireless route. Some products will work with any operating system, while others are limited to Android and iOS. 

Beyond that, choosing the best Subaru scan tool is a matter of figuring out which features you need. If you’re only interested in reading and clearing codes, an affordable option like the Foxwell NT201, BAFX OBD2 Scanner, or Foseal OBD2 Scanner will do what you need for cheap. 

For those who want to diagnose non-OBD2 systems, you’ll need to spend a bit more. Having said that, something like FIXD™ still isn’t much of an investment. You’ll get access to your climate control, airbags, anti-lock brakes, and transmission system for right around a hundred bucks. While the Launch CRP129E costs the most, it’s the only scan tool on the list that lets you turn off the oil light or reset your TPMS data.
