ANCEL AD310 Classic Enhanced Universal OBD II Scanner Car Engine Fault Code Reader CAN Diagnostic Scan Tool, Read and Clear Error Codes for 1996 or Newer OBD2 Protocol Vehicle (Black)

This is not a miracle tool! An OBD-2 reader READS CODES off the ECU. It does not diagnose. It does not know anything except what the code is. It works great for that, it is accurate, easy to use, and inexpensive ($24 now? I probably paid that 9+ years ago). This is a passive scanner, it can clear codes but not much else. It can't, for example, select what tire you have on your Honda (our Honda has 2 rim diameters and 2 tire types for each diameter to choose from, a fancy OBD-2 tool will allow you to select which one) or activate your ABS when you're bleeding brakes (like on our Suburban). I got this originally Nov 30, 2016, because my car had a check engine light ("CEL") on. I was an automotive service writer but tracking down a sensor problem was very time consuming and I didn't want to put my guys through that (the lead tech did use his OBD-2 tool to bleed the brakes on my Suburban though). So I did the troubleshooting myself. Ends up that my O2 sensor code (P0037, heater element in downstream O2 sensor is not working) ended up a burnt pin on the ECU! I had to replace the ECU to get the car to pass emissions. My registration had expired due to the emissions. After the new ECU I drove very discretely at night across the state line with the ANCEL plugged in, checked it whenever I came to a stop, and when it was ready I literally drove it to my work (where we do emissions), parked the car, and called my wife for a ride. The next morning someone ran it through emissions (I was not allowed to since it's my car) and it was good. Another car had an intermittent CEL (Chevy Suburban). Knock sensor. This vehicle was known to have intermittent knock sensor issues, especially around rain/moisture weather (water pools where the sensor is). I used the Ancel to clear the light then to see when the vehicle was ready for emissions, then brought it to emissions. I ended up replacing the knock sensors maybe 6 years later, but I passed 3 emissions tests with the sensors working only intermittently. The last time I used it was about 5 months ago, needed to pass emissions but had a new battery (and the engine was out so there was no power for a bit) and therefore the system wasn't ready ("incomplete" status for the various self checks). I drove around with the ANCEL plugged in, checked it every now and then, and when it was ready I went home and parked the car. Passed emissions the next day. I really like this tool, it's simple, useful, easy to use.

This little guy is amazing and gets the job DONE! You can EASILY find and erase codes! Nice display, easy to use, responsive, and accurate!! 10/10 recommend

Very happy with this purchase. I have an older car (2008) and have error codes regularly pop up on my dashboard. This tool helps me determine how big of an issue any of them are and how quickly I need to deal with any code. Solid value for the price. Gives me piece of mind having it readily available in my glove compartment. I appreciate how easy it is to use. I had never used one of these before and was able to connect it without any issues, so you don't need a lot of car experience to use.

A good little tool to have

Owner of a 21 Chevy Camaro. Threw a check engine code on me and I’m tired of going to AutoZone etc to ask for printouts that are often inaccurate. I went to autozone a week ago for this same light and it told me I had to replace my OIL PUMP. I bought this and scanned it because my car has been running perfectly normal I figured it wasnt anything that major. Just a sensor. I scanned with this and it came back as my oil pressure SENSOR. Just as I thought. I can’t recommend this device enough. It’s inexpensive and a MUST HAVE for all car owners. BUY IT. Forget the fancy gizmos, this is simple, direct, and EFFECTIVE

Has good basic analyzer codes and easy to read nice product for the money

wonderful tool. Very easy to use and read the code on our 2017 chevy equinox. nothing complicated at all with this. Saved me money instead of taking to a dealer or other shop. Also was shipped very fast and packaged well. Its not cheaply put together and the buttons seem durable. Plugged it in to the car and instantly it came on ready to work.

After going to auto zone to have my car scanned because of a Check Engine Light, only to find out it was a loose gas cap. I bought this one because of the great reviews and ease of use after watching You Tube. It was every bit as easy as reviews said. I am totally thrilled with my purchase & I will recommend it to my sons so the can buy their own.

Great product, even better price.

Ottimo prodotto, ha una miriade di codici e per un uso non professionale é più che sufficiente!

جيد وبسعر مناسب وبسيط وسهل الاستخدام

Me llegó en tiempo y forma y lo ocupe para revisar mi vehículo, lo cual me arrojó los problemas que tenía y es muy eficaz. En cuestión de funcionamiento es muy bueno y tiene para cambiar el lenguaje, así es más rápido interpretar los códigos.

Right out of the box, it’s super intuitive, lightweight, and truly plug-and-play. You just connect it to the port, and it powers right up without needing batteries or a setup process. Unfortunately, I ended up having to return it because it couldn't detect the more advanced diagnostic codes I needed to troubleshoot for our hybrid minivan. It’s definitely aimed more at standard engine code scanning rather than complex hybrid system diagnostics. That said, if you just need to read and clear basic check engine lights, this is a reliable, inexpensive piece of hardware that everyone should keep in their glovebox. It’s perfect for simple DIY checks,
