FOXWELL NT301 OBD2 Scanner Live Data Professional Mechanic OBDII Diagnostic Code Reader Tool for Check Engine LightGlobal Recycled StandardGlobal Recycled StandardGlobal Recycled Standard

This is one of the most useful tools I’ve bought in recent memory. I regret not having picked one up sooner. It’s paid for itself after a single use. I had a shaking in a vehicle and I could not figure out what it was. I’m a home mechanic and was dreading taking it to the shop. This told me that this issue was a simple misfire in a specific cylinder and I found a loose wire and fixed the problem in a second. Since then, I’ve easily diagnosed and quickly fixed other issues with other vehicles. Very easy to use. I read the instructions but they weren’t even necessary, it’s that intuitive. If you’re reading this, just pick one up already.

Works great, very easy to read & figure out what needs fixing. Great functionality and a very good device for the price.

This OBD2 scanner is a solid tool for car enthusiasts and weekend mechanics. It has a bright display that's easy to read in both daylight and garage lighting. It’s multifunctional, offering a range of diagnostic features that make it great for DIY jobs.That said, the instruction manual is hard to read due to the small lettering, and the learning curve can be a bit frustrating, especially if you're new to these kinds of tools. However, once I got the hang of it, it solved my check engine light mystery in minutes, saving me a trip to the mechanic. Overall, a very useful tool if you're willing to spend a little time getting familiar with it.

I purchased the FOXWELL NT301 OBD2 Scanner after my check engine light came on, and I couldn’t be happier with the decision. This scanner is incredibly easy to use, even for someone with limited car knowledge. Just plug it into the OBD2 port, and it powers up instantly — no batteries or setup needed.The 2.8" color screen is clear and bright, and the menu is very intuitive. It reads codes fast and gives detailed definitions, so you don’t need to Google what each code means. I also love the live data graphing feature, which helps track engine performance in real time. The I/M readiness button is a handy bonus — great for emissions testing prep.I’ve already saved money by diagnosing and clearing codes myself rather than running to a mechanic for every issue. It even prints data for records if needed.If you own a car (1996 or newer), this tool will pay for itself in no time. Whether you're a weekend DIYer or just want to avoid unnecessary shop visits, this is one of the smartest tools you can keep in your glove box.

Works like a charm. Goode value for price.

this device does its job well. I used it on my bmw e46 2005 330Ci to eliminate a possibility of broken traction module and other brake related issues. it also shows emission information which is important here in VA as we have emissions inspections every two years.

I was happily surprised that I could own a code reader for a very reasonable price. My neighbor has helped me out before but I was traveling when that "check engine" light came on last week. I prefer to have some idea what might be the issue before I take the vehicle to a mechanic since the problem can be just a minor one. Your vehicle starts this guessing game with you and it can drive you crazy. Easy to operate.

Hailing from the shade tree mechanic era of points & plugs ignition and the carburetor accelerator pump, most of what goes on that fills the NT301 data stream is way above my pay grade. While the likes of EGR, O2 and catalyst are not beyond my understanding, the value 12.226 associated with a VPWR(V) certainly is.Being the consummate motor head, the dreaded "service engine soon" lit up for the first time from behind its mask on my dashboard finally gave me the impetus to purchase a code reader. Upon some goodly research, and a screaming hot Amazon deal (a few bucks more than the NT201), I settled on the NT301 and I'm not disappointed.I had two reasons for the purchase:1) To read the code(s) and have some knowledge in advance of a mandatory visit to a repair shop as that "service engine soon" (or "check engine") light is grounds for instant rejection for my county's annual inspection, even if the good ol' tailpipe sniffing and other "hands on" checks would pass the Federal mandates. As well, it might reveal a serious issue that shouldn't be ignored.2) To satisfy that ubiquitous question: how can one turn that light off if one wanted to? Searching teh googuhl for either "check engine" or "service engine soon" returns gazillions of hits with bazillions for ODB scanners. Makers, sellers, yoot oobs, reviews, best of... oh my. Not to mention, "over 1000 results" here on the 'zon.I opened NT301_OBDII_V1.00.pdf (the equivalent of the printed manual) in Tracker Software's PDF-XChange Viewer and used its powerful search engine to help out.The words "check engine" or "service engine soon" do not appear in the manual.Instead, one finds section 4.2, Erase codes, for the two choices - an "Erase hot key" and an Erase Codes item in the diagnostic menu. The reference to the hot key appears no where else.The down key has a big old ERASE printed on it. Section 2.1 refers to that as a "Quick access to the Clear Codes function before going to diagnostic menu..." And that's it.Clear = Erase?? Hot key = Quick access??Fortunately, using the down/ERASE key (you really, really need down) didn't seem to erase or clear anything. My "service engine soon" light remained shining bright as my county and the Federal bureaucrats and repair shops far and wide would have it. I'm OK with that, but in that respect, an obscure "Erase hot key" is dangerous if that shuts off the light.Yet, the question remains, does NT301 anything extinguish the light?Another documentation shortcoming is illustrated in figure 4-30. Although the green check mark and the no symbol can be presumed, my result had two white-X-on-red results with no explanation on what that means. Considering the Federal legal implications of the environmental technology presented by the the I/M Readiness Status, the documentation focuses only on the the three simple LEDs while fully ignoring the really neat Diagnostic Menu Screen.All that said, even at the regular price, the NT301 seems to deliver a great bang for the buck. Further, I'm motivated to hit the books, uh, internet and study up on some of this OBD stuff.Kudos for the 08/01/18 firmware (v4.24) burn date on an 08/15 purchase. A pleasant surprise.But I've got to ding two stars for omitting The Obvious from the manual. Some other reviewers here are less than satisfied with the manual as well. Admittedly, the manual should not be held to the standard of a concise tutorial.SIDEBAR: The problem was repaired; the car passed emissions testing. I still have the two white-X-on-red symbols in the I/M Readiness Status Diagnostic Menu Screen. So, what the heck...
