    Autel AutoLink AL519 Complete 10 Modes of OBDII Tests

    • Read Codes

      AL519 engine fault code reader can access the powertrain module to pull generic codes(P0, P2, P3, and U0), manufacturer specific codes((P1, P3, and U1) and pending codes to pinpoint the fault locations that lights up the check engine light. Reading codes can be done with key on engine off or with key on engine running depending on the specific vehicle it’s testing.

    • Clear Codes

      Erase the DTCs when proper fix needed has been done and the fault is not longer present. Erasing the fault codes may allow the auto scanner to delete not only the codes from the vehicle’s on-board computer, but also “Freeze Frame” data and manufacturer specific enhanced data.

    • Live Data

      Live Data functions allows you to view the live PID(parameter identification data) data of vehicle’s computer module(s) in text, graph to check the status of various sensors. It also enables you to record manually or automatically 5 frames of live data before and several frames after a trigger event like when a DTC is set and for later data playback and review.

Doesn't really lag and displays live OBD data pretty quickly once you scan it

The scanner works really well. Doesn't really lag and displays live OBD data pretty quickly once you scan it. I used this scanner to diagnose a bad O2 sensor. I really enjoy how the scanner can show you readiness monitors (for DEQ testing) and lays it out in a simple to understand manner. I am a professional mechanic and use this scanner daily as a "quick check".

5.0 out of 5 stars Way better than expected!

I've used this on 6 different cars in a week's time and can't complain. The display is bright and legible, controls are self explanatory if you've used a scanner before, and the quality is obvious once you unzip the case. I'd say it was money well spent since I've wanted for a while. Of the 6 cars I used this with, all codes were found (a lot more than expected) and easily taken care of before clearing. I did read the manual before using it in case you're wondering. It does give detailed information on all the vehicle modules it links to while scanning. The rest is mainly a beginner intro on use. It reads the codes and gives a good description of the probable fault. I read a review where they thought the case felt like cheap plastic and can't disagree more. The outer "sleeve" is a little loose to absorb impact in a fall. I tested this It survived without a scuff. The zippered nylon case adds another layer of protection when not in use. It also has a Velcro pouch inside for the OBD-II interface cable, software CD, and USB to mini USB cable. I would highly recommend this over any scanner you can pick up at the local parts store. You're not going to get a color display that large at this price point!

Great bit of kit!

Ideal tool. I have already saved £100s. Simple to use and very accurate.


This product is one of the best auto scan tools that I have ever used and well worth the price.

This product is one of the best auto scan tools that I have ever used and well worth the price. 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. After I repaired my truck, my daughter drove it down the road as I ran a complete analyses on my truck's performance. I could not believe all the information the tool provided. Buy It!
