foxwell-nt301-vs-konnwei-kw850-which-is-the-best-obd2-scanner-with-error-code-definitions

As a DIY enthusiast, I like to get my hands dirty. I like to carry out my repairs whenever I can. Whether it is a chipped piece of furniture or a broken down mower, I can always go to the internet for some help.

I started repairing vehicles at a very young age. Since I did not have the right tools for the job, I often had to consider the professionals. I was watching my local auto repair serviceman working on my vehicle when I noticed him use a handheld tool before determining the problem, which only took a matter of minutes.

I was impressed. I looked online to find out more about this scanner and bumped into this Foxwell NT301 vs Konnwei KW850 OBD2 comparison.

Foxwell NT301 vs KONNWEI KW850 – how do they differ?

Let us look at some of the key bits of difference between these two scanners

Ease of use

The best OBD2 scanners are developed for enhanced ease of use. They feature ideally placed hotkeys for easier diagnostics. While the Foxwell NT301 offers plug-and-play support, the KONNWEI KW850 features a one-click readiness module that may take up one more click to start. Nonetheless, both models are very easy to use.

Display and diagnostics presentation

The larger display screen of the KW850 makes it better than the NT301 in terms of data presentation. While it is still sufficiently clear, the NT301 falls short of the wide KW805 display screen. Both models feature LED lighting which can help increase the ease of diagnostics.

Warranty

Like other Foxwell products, the NT301 is compact and sturdy. It features a great design as well as the use of high quality materials to ensure longevity. The brand offers a 12 month warranty on this scanner.

The Konnwei KW860 is also similarly well designed. It is lightweight but compact, and includes a storing case. However, it offers a longer 36 month warranty.

Vehicle compatibility

Locally, these scanners offer compatibility with a large range of vehicles. However, the KONNWEI KW850 is somewhat limited in its coverage of vehicles manufactured outside the US.

Unlike the NT301’s blanket coverage for international models built beyond 2004, the KW850 offers coverage for models built after 2007.

FAQs

Can I update my scanner on my MAC PC?

You cannot update your scanner through iOS devices. However, all Windows 10, 8, 7, Vista and XP versions will do.

Will I be able to decipher the error codes?

Thanks to a large look-up library, these scanners offer a generic definition of the problem that allows you to pinpoint and address it.

Do I need to dismantle my car to access the OBD2 port?

There is no need for any special tools. Your car’s OBD2 connector is located in a visible area beneath your dashboard.

Will these scanners test my battery?

Your OBD2 scanner is limited in its ability to offer battery registration, unless specified. The KONNWEI KW850 can enable you to monitor battery health.

Will the KW850 work on my imported diesel vehicle?

All post-2004 models will be compatible with the scanner, provided they feature an OBD2 port.

My verdict

Having limited experience will undermine your ability to carry out DIY repairs on your car. Even the most detailed YouTube tutorials just won’t help if you do not know what you are doing.

Even though I enjoy working on repairs, I could not risk damaging my vehicle even further. The Foxwell NT301 vs Konnwei KW860 comparison helped me solve my problem.

After trying out both scanners, I found Konnwei KW860 to be more convenient for use thanks to its extensive lock-up library.

Despite my initial inability to understand the diagnostic presentation, I was able to follow the codes to understand what my vehicle needed. I can now carry out DIY repairs from the comfort of my garage.
