Autel MS300 OBD2 Scanner Code Reader, Turn Off Check Engine Light, Read & Erase Fault Codes, Check Emission Monitor Status CAN Diagnostic Scan Tool

As with anyone who has had the check engine light pop on while driving, my heart jumped to my throat when that baby lit up my dash on the way to work. And then it splashed back down to the pit of my stomach...hard! I guess it is the not knowing of what is hurting my little commuter. I wanted to know. This brought on the search for a dependable, but not expensive, scan tool to find out on my own what the heck was going on. I found this little jem and decided to give it a shot based on the mostly positive reviews it had. NO REGRETS!This product worked without any glitches. My vehicle is a 2003 Hyundai Elantra GLS and I think the hardest part of the process is finding the link connector in the car (it is down below of the steering wheel under the driver side dash, if anyone is interested, you have to feel for it because it is not visible). Once I found it though, it was all down hill...in a good way. It fit perfectly and worked as stated in the manual.Just follow the steps indicated and you will get the info you need. In my case, all I was looking for was the reason for the check engine light to turn on. I got my answer with this little scan tool. In less than five minutes I got the DTC code (this is explained in the manual) that set of the MIL. Once I got the code, I went straight to the auto shop and told my mechanic what I found. I have a good honest "guy" that was surprised, but also pleased, that I had pin pointed the problem for him.But, the tool also gives more info on the car than just the problem codes. It can pretty much give you the status of most of important components in the car. It was a relief to find out my car was in great shape, except for just one code. Very much a relief.Well, from my positive rating, you can figure out that I definitely recommend this producted. It is a simple, but valuable tool to have if you drive every day and depend on your car. I have used it only once, and will be happy if I don't have to use it again. I mean this in a good way, but if I ever get a check engine light, it won't freak me out because I have my own diagnostic tool to see what is going on with my beloved 4-banger!Note: The manual comes with a list of generic code definitions. Once you find the code, you can use their listing, or look it up on the internet. I did both just to verify.

i can't believe how simplistic this device is compared to the high end scanners and it just works. i mean what else could you ask for. its so simple. plug in, turn key, it auto detects the car's programming and if there is an active code will automatically scan. is very fast and effective. i used on 2 cars, my friends Pontiac grand am and my Pontiac g6. my g6 had no codes on it just wanted to see the difference. if there are no codes active it will not auto scan. however you can still manually make it scan, and it also can see certain things from your emissions systems. not everything but some things, but it really just tells you if they are working or not. if the programming is compatible, it can also pull the VIN off the car and as i found out, i can't on every car. my g6 it could see the VIN, while my friends grand am, it could not. still for the small affordable price of 20$ has already saved me 110$ in diagnostics fees. im sure will save me much more in the future. The other nice thing being, even if this thing broke after 1 use..... it cost 20$ and electrical diagnostic fees at a shop where i live are 110$..... even ONE use would pay for this product. and yes it doesn't give you a description of the code but who cares.... most the software in high end scanners has to be constantly updated to be accurate. it reads code, you type code in Google and presto..... you saved yourself a ton of cash. i like cash. if you like cash you can order too!edit (11-4-15) - I have owned this for over three years now and has been extremely valuable. I have had several different cars since the time I originally bought this and used at least a half dozen times on family/friends cars to pull codes. This thing is great, even though these can be borrowed for free at auto parts stores to pull codes, it is more convenient to do it yourself in your own home on your schedule. This thing even stunned me when it could read a 2004 Audi A4 as VW and Audi normally are on a completely different communication/diagnostic system than most other cars in the world. Also I am pretty rough with this thing because it was so cheap and I wouldn't care if I had to replace and it has continued to work. It may be cheap but has been extremely valuable to me in pulling engine codes. I wish there was a rating above 5 star!
