Autel AutoLink AL519 Car OBD2 Scanner, Classic Enhanced Mode 6 Engine Fault Code Reader OBDII CAN Diagnostic Scan Tool, One-Click Smog Check, DTC Look, Upgraded of AL319

I replaced my old OBDII unit, because when I would read the codes on my 2005 Lexus ES300 (P40002, P0004 and P0006 codes), upon clearing the codes, I would find that my SRS lost it's calibration and my car computer would think it was in the middle of a "roll-over" and would turn off the Anti-lock brakes and traction control. This meant that I had to re-calibrate the SRS every time I read the codes. My old meter read the codes, and hinted at the problem - which meant hours looking for a vacuum leak. All told - hours wasted and lots of frustration.So, I got this little gem. It read the same codes, as expected - and then SUGGESTED some easy fixes. Guess what? An $8 replacement gas cap fixed my problem. And, because this meter reset the codes and is compatible with CAN-Bus, it didnt' screw up my SRS and ABS system after reading the codes. It does so much more than my old meter!And another plus. If you are like me; you buy this, and generally only use it a couple of times a year. And, likely have batteries that get left there to rot, and hopefully they are replaced before they leak. This requires NO batteries. That's right - it just taps into the vehicle's battery and takes what little power it needs to run the CPU from the car - so you can store it indefinitely without worrying that the battery will leak acid and destroy the unit. It boots up in about 10 seconds, and autel has firmware updates online so you can keep it updated. You will need WindowsXP or newer. I had no issues with Win10. Update was easy and pretty fool-proof. Included software also allows you to capture screen-shots to review on your PC (again, Windows only - not Mac - I couldn't get Parallels to play with this on my Mac running El Capitan). So - as far as I can confirm - you will need a PC running WindowsXP or later.I also had no issues getting this to connect to my 2003 Toyota Tacoma - so it works perfectly with "older" vehicles too. It connected with my vehicles flawlessly, every time. BTW - I updated to the latest firmware on the autel website upon receiving the unit. Again, to be clear - it's straightforward, the download is relatively small, the update takes less than a minute and I am extremely satisfied with this purchase.

Have to smog a vehicle (its been a while since I've done that) and my Bluetooth adapter finally died. I was looking for a complete all in one so I didn't have to link it up and mess with the adapter, this scanned both vehicles and quickly connected to live data and IM's readiness. The user interface is really slick, and easy to read on the color screen. I remember when this level of functionality was way pricier! Didn't even have to look at the manual or look up codes they had a little help menu with each meaning right on the screen at the touch of a button, O2 wasn't ready (IM's) and found a dead clutch pedal switch, easy part swap and easy to see that the O2 was responding appropriately via live data graphs. I was able to read up on how to set it and with a little driving from the manual it set everything and the switch replacement worked as well. Now the car is all ready to go in. The interface is super easy and it picked up a few other things reported that didn't show on a cheep-o scanner. I was able to get all readiness codes set and verified and all the other things fixed up with out wasting a trip. Its a little pricy for the feature set, but they seem to have done a good job with this one, so I'd say just for the easy of use / navigation, and stored lookups and help, this was a good grab and go tool. For a basic scanner it helped for my use case so if that's all you need this one made it way easier. Graphing data was a huge plus! Graphs are a little slow but perfectly good enough for a handheld tool (look its not a Textronics scope here). I was able to capture O2 stream data and changes reasonably quickly with a good sample rate, that I could verify it was in spec and wasn't having to guess. It graphs most PID's smoothly on the ODBII port. If you need some other feature sets you'll probably pay more, but this was worth it for just being easy to see, ready, and troubleshoot with out looking up anything in a tiny booklet or having to go in and google. Autel FTW!

I had never used an OBDII scanner before, but decided to get one when a co-worker pulled his out of his car and plugged it into my van to see what was wrong when I had some mis-firing going on. I purchased both this wired unit and a wireless unit, the ieGeek® WIFI Wireless OBD2 Auto Scanner Adapter Scan Tool for iPhone iPad iPod. Both work well, but the wireless version has the added benefit of being able to monitor engine functions LIVE, so if something intermittent is going on, you have a better chance to spot it if it is not leaving the MIL codes. The Autel AL519 will display live sensor data as well, but there is a cable in the way and I already have a nice dashboard mount for my iPhone. To make the ieGeek WiFi Wireless work, I purchased a $5.95 app at the iTunes App Store, so the real price of the wireless model is about $35.Since I am new to this OBDII scanner stuff, the Autel AL519 might have important features I have not tried yet that make it a better overall choice, but for the amateur like me, I think the wireless devices make more sense. I also purchased a BlueDriver ODBII wireless scanner, but it was more expensive and even though it came with a free iPhone and Android app, doesn't seem any better than the ieGeek version. The BlueDriver is more compact and easier to leave plugged in all the time, but for the price difference you really need those features to make it worthwhile.I plan to leave one device in each of our families 3 cars, so they are readily available when needed.
