Its DTC query library offers fault analysis and inspection methods, helping you determine why the check engine light is on. After fault repair, it can quickly clear the code. Moreover, It is also equipped with an I/M readiness feature that checks if your vehicle is ready for the S-mog test, helping you pass your annual inspection with ease. If you're still unsure about Father's Day gifts, NL101 could be a great choice.
- Multi - Function: It is both an OBD2 vehicle code reader and a battery tester. It can monitor the health of 6V and 12V batteries, and in just a few seconds, it can check battery voltage before and after the vehicle ignition. With this data, you can get a clear picture of whether your vehicle has enough juice to start the engine and whether the alternator is charging properly. This helps you prevent roadside failures in advance and effectively reduces unnecessary repair expenses.
- Excellent Compatibility: Our OBD2 scanner diagnostic tool is suitable for American models after 1996, Asian vehicles after 2006 and European models after 2002, covering more than 99% of car brands in the market. Whether it's a car, SUV, pickup, light truck, etc., it's a perfect fit. If you are not sure if it is compatible with your vehicle, please feel free to contact us for assistance.
- Easy To Use: No need to charge, plug and play. It is equipped with a 2.4-inch color screen, with an intuitive and clear interface that displays all real-time engine parameters in text and graphic form, such as engine speed, airflow sensor, intake temperature, fuel rail pressure, etc. Even inexperienced users can easily compare fault readings with normal values using our OBD2 scan tool, thus quickly identifying the cause of vehicle malfunctions.
- No Subscription Fee: By owning the NL101 car code reader, you can enjoy the full functionality without any additional cost. It can be connected to a computer through a USB port to print diagnostic reports and enjoy lifetime free software upgrades, allowing you to access new parameters, features, and the latest vehicle data without worrying about obsolescence. It also comes with a dedicated protective case worth $19.99, which can be used to prevent equipment wear and tear.

This thing is awesome. I was looking at buying an expensive one and this was referred to me by my dad’s mechanic buddy. This works excellent, is easy to use, and does everything I need. Very happy with this purchase.

When I used to work on cars this would have been a super handy tool to have. Now, I don't work on cars as the friend whom I used to fix old cars up with passed away. I am just not into doing that sort of thing. Anyways, I did think owning an OBD2 scanner would come in handy for me to clear codes and to keep an eye on the details of my new 2019 Ford Escape. Being a brand new car I didn't think I would have any issues but at the same time if something seems odd being able to narrow down the cause before calling the dealer always makes for getting a repair done quicker, at least in my experience. The problem I have found with this OBD2 scanner is that not all the functions work with my car. This was pretty disappointing but on the bright side being able to clear basic codes and check if my battery is at a good level is nice. I have used OBD2 scanners with fewer functions and harder to see and read screens. The buttons are easy to press it powers on from the OBD2 port so no need for any double AA's to power it. The one thing I don't really care for on the device is that they use a Mini USB port and I have that shown in the photos I took for firmware updates. Mini USB is outdated and sometimes it’s a bit harder of a cable to find in stores. I would have gone with Micro USB or even better, USB-C. All in all, if I would have had a different model car all the functions should have worked great. What I was able to use gives me faith that the device is a good buy.

The media could not be loaded. Awesome tool! It ran both 02 sensor tests in a matter of seconds on my 2008 Toyota Tundra! Pulls codes, erases codes! Easy to use, well built! 3 foot cord, nice storage case. Happy with this purchase! SEE THE VIDEO OF HOW TO USE THIS TOOL! Very easy to use, no apps required.

Good basic scanner. no issues. have used it a bunch of times and even bought a second one for my son.

I wanted one of these for my 2012 Prius c so if a check engine light goes off I can find out what it is. I also chose this one because it checks the status of the 12v battery. It is so simple to use. I just plugged it into the OBD II port and it turns on and you click on the picture of what you want it to do. Nothing wrong with my car and it found nothing wrong. I got it for $40 as a prime day deal. Great deal!

What was great about it, it had a case- a nice touch. The case was semi hard-shelled with a zipper and webbing to keep the scanner in one place while being mobile. Why the low rating? No user error issues, it was just not that great on the keypad. For some reason, I would press the keys, be it arrow or enter or back or home and sometimes it would work and sometimes, nope- had to press repeatedly. The other issue, the shiny surface although it looks great indoors, really made it hard to read outdoors- not a huge issue since I would just tilt the device up or down a bit, but there's something about that ultra-shiny surface, maybe a matt finish would have been better around the LCD at least. So back it went, I'm sorry NEXAS and by the way, if you are like me and went to their website first to look for updates/firmware, etc...nothing available...nothing.
