What customers say about "Key Specs"
Autel AutoLink (AL319) OBD2 Scanner
  • As a code puller? hard to beat the speed this has. It gives you all the details as it tries all the OBD-2 Protocols and does it quick too.
  • This works beautifully. Instantly detected car's protocol and told me everything I need to know. It even has a one touch button labeled "I/M" that you can press to tell at a glance if your car will pass emissions.
  • Just wanted to post a review to let people know that this does work on a '99 Lexus LS400 and a 2000 Lexus LS400 even though Lexus isn't an option on the list of types of cars, just click Toyota and it reads the codes fine.
  • It includes a fair number of manufacturers and models so it goes beyond simple OBDII scanners. It also very quickly flags whether sufficient Drive Cycle tests have completed for emission inspection purposes.
  • DOA. Connected it to my Windows 7 PC and message the device connected had failed. Plugged the scan tool into OBD II port on car and it determined the protocol, but just hung in an endless loop from there and did nothing.
Autel AL519 AutoLink Enhanced OBDII/EOBD Scanner
  • Checking readiness codes are done automatically once the meter was plugged in. this took less than 10 seconds. There are 3 LED indicators on the keypad that illuminate to indicate readiness.
  • Exactly what I needed to read the codes from our '14 MB G550 and '15 Honda Fit. Tested and the tool communicated with both of these vehicles.
  • This vehicle scan tool is amazing! It worked great on my 2002 Honda Civic. It found my SRS error code and helped me diagnose exactly what the problem is. It also can erase SRS codes.
  • Stopped working less than a year after purchasing it. Stopped displaying the menus and would not produce any codes.
  • It will scan for codes but the live data is not very good. it has no missfire data . it is a cheap meter to check and erase codes. it works for the price i paid.

What customers say about "Diagnostic"
Autel AutoLink (AL319) OBD2 Scanner
  • I used it to diagnose the problems on my daughters Nissan Maxima. It showed two codes. One for a bad camshaft position sensor and one for a misfire on cylinder 3. I replaced the sensor and the #3 cylinder coil pack. Car runs great now.
  • Has worked well when the check engine light comes on. I had an issue with my coolant thermostat and was able to diagnose it before visiting the mechanic through the web with the code I got and the symptoms I had.
  • Finally, a code reader that’s easy and versatile! I like that it clearly states what the problem is without having to look up codes in the manual or online
  • Excellent small code scanner. I reset BOTH of the annoying check engine lights on my 2011 Wrangler and my wife's 2012 Liberty cause by the gas caps being loose.
  • Reads codes from engine only. It can not read codes like ABS, handbrake etc..
  • This product does NOT read ABS codes on Honda vehicles, as the claim that it will. I experienced terrible customer service trying to get them to make it work.
Autel AL519 AutoLink Enhanced OBDII/EOBD Scanner
  • I do not want to list all the features but they all worked on all the vehicles. I could read all basic live engine parameters or just a few from my own selectable list.
  • I could look at any individual live data in graphic form one at a time. I.e- I was able to look at the O2 sensor voltage sweeps live, throttle position sensor %, engine RPM, etc.
  • Haven't had any issues, but made this purchase to diagnose my cousin's '10 Lexus RX350. It found the fault code and interpreted the fix. Replaced the O2 sensor, cleared the code and all is back to normal.
  • My check engine light was illuminated on my pickup and the Autel Tool read the codes and provided information as to what was wrong. The dealership read the same codes and confirmed that the problems were exactly what the Autel AL519 had indicated.
  • I love this scan tool. It's probably the best investment tool I've ever bought. It works great and tells me what the codes I have on my 2000 Ford F-150.

What customers say about "Features"
Autel AutoLink (AL319) OBD2 Scanner
  • Large color screen. (Easy to read and you get lots of info in one shot, minimizing scrolling).
  • Pretty fast scan time. (OBD readiness scan is done under a minute).
  • I really like the Live Data and I/M Readiness features (particularly relevant to my O2 sensor failure in preparing for an upcoming state inspection).
  • The cable could be longer. (The screen barely rises above the steering wheel after plugging it in).
  • Difficult to update. Even though I followed instructions. Tried it for the fourth time but still couldn't.
  • When I tried to update the software the device work windows vista and windows 7. Nothing about windows 10. I could not update it.the car scan is good, found the code problem.
Autel AL519 AutoLink Enhanced OBDII/EOBD Scanner
  • The live data is great for checking all the vehicle sensors, and it can even graph the data in real time. Very cool product. It is very well built, feels sturdy, and the buttons are very good and strong.
  • very nice! The quality is obvious. It connects and lists the codes. On some it will tell you the possible reasons and possible cost associated.
  • I bought thus because the engine light came on in my 2000 Hyundai, the scanner worked perfectly 98% of the features worked on my car. I would totally recommend this tool.
  • The best value scanner out.. It works perfect. Saves me money from taking it to a mechanic for a diagnose.. Live data is one of the best features and so is the IM readiness test.. Helped me pass my cars smog test.
  • This is a lightweight product made in China. The outer protective rubber cover is more of a semi-flexible soft plastic. The case plastic is not a high quality flexible plastic as used on high quality DVOMs.
