Rexing - Universal OBD II Scanner & Engine Code Reader for 1996+ Vehicles - Black

This is my first OBD reader. For years, I felt blind about what was happening with my cars—whether a code didn't show up on the dashboard or when a check engine light actually came on. I couldn't be happier with this fantastic tool. As a first-time user, I am really impressed with all the data I can see and understand. Thanks to its simplicity and intuitive user interface, menus navigation, it is user-friendly, and the screen quality is excellent for its 2.8in LCD size. I also really appreciate that it comes with a physical instruction manual instead of forcing you to download a PDF file like other brands do. I have three cars: a 2013 Subaru Forester, a 2023 Subaru Crosstrek, and a 2020 Kia Sportage. I was eager to try this reader on all three and ended up learning a lot. For example, I discovered the Sportage had been having low voltage issues for quite a while, which I wasn't aware of because there was no dashboard error. It turns out that the LoJack tracking device installed on the vehicle was draining too much power from the battery while the engine was off. I was able to fix this immediately by extending the unit's polling time! Meanwhile, the Forester reported a 10-degree higher engine temperature than normal, which is something I now know to address by replacing the coolant or checking the fans. I dare say that thanks to the Rexing OBD II, I saved myself from potentially getting stranded on the highway. This reader is truly plug-and-play. There is no setup required—you just connect it to the car’s OBD port and that’s it. It doesn't require internet access, creating a user account, or the process of gathering data first and then connect to a computer in order to read the codes. You don't have to deal with Bluetooth pairing or installing a smartphone app just to access your data like you do with other units. Thanks to the built-in display, I can see live data. Best of all, it doesn’t need batteries, and I can easily clear check engine light or emission codes without having to disconnect the car battery to clear error codes as I used to do before getting this reader. I already own a few other Rexing devices (a dashcam and a wireless car adapter), and all of them work great. It is a reputable brand with quality products, and this reader is no exception. The Rexing OBD II is a very affordable, useful tool that you can easily keep in your car or truck to quickly diagnose issues on the fly. I am incredibly pleased with this reader!

I recently picked up the Rexing OBDII-R1 and so far it’s been a solid little scanner. Setup was simple — just plug it into the OBD2 port and it powers on right away. The interface is easy to navigate and it quickly reads codes and vehicle information without any hassle. One thing I really like is the amount of information it gives you beyond just reading engine codes. Features like voltage monitoring, the built-in code library, live data view, vehicle information display, and freeze frame playback make it feel more useful than a basic scanner. I also like that the freeze frame feature lets you go back and look at stored data afterward instead of trying to catch everything in real time. One small issue I noticed is when reading DTCs, the screen says “press any key” to continue, but pressing the OK button keeps it reading instead of moving forward. You have to press a different button for it to continue, which was a little confusing at first.

I used the Rexing Universal OBD II Scanner on my 2018 Toyota Camry, and it paid for itself right away. The OBD II port on my Camry is under the dash near the driver's knee, was easy to plugin. The scanner powers up from the car, so no batteries needed. The screen is easy to read, and the physical buttons make the menus simple to follow. It helped me spot a battery issue. The voltage reading was lower and allowed me to catch it, before I was stranded. Without this scanner I wouldn't have known until the car failed to start. The built-in code library also explains what each code means. It's focused mainly on engine and emissions diagnostics, so it won't read ABS or airbag codes. Still, its extremely useful to catch early issues and avoiding a surprise breakdown, it's a great value and easy to keep in the car.

I own a 2018 Honda CR-V and a 2006 Honda CR-V and often work on the car myself to avoid going to a mechanics shop when possible. This is a very useful OBD II scanner since its very easy to use and the UI is pretty easy to understand. Having an OBD II scanner is useful and if you are like me and like to work on your own cars this tool can save you from having to take your car to a mechanic shop. The entire unit is self-contained meaning there is no bluetooth or app you have to download or have to signup for. You just plug the unit into your car and you are good to go. It does quite a bit more than just display an engine code. You can clear codes, view live data, check battery voltage, and use the built-in code lookup to get a better idea of what a code actually means. That's especially useful if you just want some basic information before deciding whether something is an easy fix or needs to go to a mechanic. Overall, it's simple, convenient, and a great tool to keep in the garage or even in the vehicle. Definitely useful for taking some of the mystery out of a check engine light. The Rexing OBD II scanner did not find anything wrong with my vehicle.

This is an extremely easy to use OBDII adapter that will make your life easier. There are numerous functions that it can provide, but the main code reading and code clearing capability is the most common and super easy. The four best things I like about the product: 1.) It has a cable and doesn't require a phone, Bluetooth, batteries, etc. Just grab it and use it. 2.) The display is wonderfully lit and easy to read. Even some of the Bluetooth apps that connect to wireless adapters are a pain to read and understand. Not this one. 3.) The buttons are very tactile and easy to understand and execute. I could plug this into a car, find the codes, write them down, clear them, and be on my way in less than 2 minutes! 4.) The cost! It's such a good price that there is no excuse to not have this in your glove box or automotive toolbox in your garage. It's fast to load, easy to read and navigate, and works every time.
