OBD2 Programming Software: The Best Options to Choose in 2020

You don’t need an expensive scan tool when you get the best OBD2 software. With many programs available very cheap (or even free), OBD2 software lets you easily and affordably diagnose car issues at home. That gives you peace of mind and saves you money at the mechanic.

We’ve reviewed 10 of the most popular OBD2 software to highlight their strengths and differences. While they vary widely in price and functionality, there’s something on this list for every user, from absolute beginners to professional mechanics.

What is OBD2 Software?

OBD stands for “onboard diagnostics,” and is a protocol included in all modern vehicles. OBD2 software lets you access and interprets this data. Just connect your device to your car with an adapter, and you’ll get dealer-level access to emission data, sensor readings, and diagnostic trouble codes.

Differences Between OBD2 Software and OBD2 Apps

Most OBD2 apps are designed to work with a specific adapter. Popular versions include BlueDriver and FIXD. While these all-in-one systems are convenient, they can also be limiting when it comes to user control.

With OBD2 software, your options are more open. Most work with a variety of different adapters and offer compatibility for more vehicles. This makes them especially appealing to DIYers, allowing easier repairs and a more thorough diagnosis.

When it comes to your adapter and computer, FORScan has a broader compatibility. There are versions for Windows, Android, and iOS. Though the desktop version has the most features, the mobile versions are still handy for diagnosing trouble codes. You also have multiple options for which OBD adapter to use—basically any adapter with ELM327 support will work.

Along with diagnosing trouble codes, FORScan gives you the power to customize your vehicle. This program can view and re-program most electronic modules.

AutoEnginuity Software

How useful you find AutoEnginuity will mostly depend on what kind of car you drive. For some vehicles, it’s a powerful diagnostic tool that can read trouble codes other scanners don’t see. With other manufacturers, though, its diagnostics are limited to those supported under OBD2.

At its best, AutoEnginuity can diagnose the airbag, anti-lock brakes, and electronic instruments. It also performs bi-directional active tests, so you can identify mechanical components that aren’t functioning correctly. This support extends beyond OBD2 to include vehicles made in Europe that are EOBD compliant.
