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

Fantastic. Does what I need, reads engine codes, and can reset them Amazing tool for the price It gives you a readout of the codes and you have to look them up online. You can pay 3or 4 times this to get that feature but why bother. For $20 it's perfect

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!

for those with link error, I didn't read the manual but you need the ignition in the ON position (not ACC or OFF). For those with codes that it read that had already been repaired... your mechanic should have cleared the codes in the computer after the repair but did not. Now you can clear them yourself. :) It's possible the repair didn't work, either, but if the MIL (malfunction indicator lamp, aka check engine light etc) didn't come back on, you should be fine. ----------------------------- This Autel scans my 1998 Subaru Legacy and read the P0440 code just the same as the Actron. It cleared the code successfully and the MIL turned off. This unit also scans my wife's 2010 Toyota RAV4, but it doesn't have any check engine light to confirm codes or any of that stuff. The included manual comes with generic DTC definitions, but the definitions are so short you need to search them on the web anyway to translate and determine the severity. That's true with just about any scanner, especially those in this price range so I was expecting that. The manual does not list manufacturer specific codes that the tool presumably reports, but you can get those on the web. I've found that obd-codes dot com to be a good resource for _most_ DTC generic and manufacturer specific definitions. It also includes other details for generic codes that are helpful. It is true that most auto parts stores will scan your car for free, but that's not always convenient. Plus, if you have an intermittent problem that occassionally trips the MIL, you might dismiss any future instance of the MIL as the original issue, and potentially cause harm to your vehicle. If you own a scanner, it's easy to regularly verify. I also own a more expensive Actron CP9180 but I bought the Autel to leave in my car at all times. Since MS300 so inexpensive I wouldn't be too upset if it gets baked in the summer heat. This product feels like a toy (very light and it has a short short cord...maybe 18"), but it seems to work. I only gave it 4 stars because of the feel of the product, but quite honestly I wasn't expecting anything more based on the price and the fact that these are made in china. My Actron has a lot of features that I'll never use (I'm just a consumer, not a mechanic), but it is a solid product that will presumably last much longer than the cheaply made MS300. Even though I paid a cheaper price for the Actron on eBay, you can get three MS300 tools for the same price of the Actron, and the MS300 tool has every feature that normal consumers like myself need.

Works great. Give correct codes. Easy to use
