To ensure a smooth setup and avoid any installation compliance issues, please review the following technical requirements for our professional diagnostic tool:
- Antivirus Compatibility (False Positives): > Because most aftermarket diagnostic software utilizes deep-system emulation to interface directly with your vehicle’s ECU, strict security tools (like Windows Defender) will frequently flag it as a threat. This is a standard false positive. For successful installation, the software must be added to your antivirus “Exclusion List” or the antivirus temporarily disabled during use. If you are uncomfortable with this standard protocol, please consider alternative options.
- Pre-Installed Software Activation Required: > If your package includes a pre-installed hard drive (HDD/SSD), the system and diagnostic software are securely locked for transit and require activation before first use. Upon receiving your package, please contact our support team immediately to get remote activation service. It is not defective; it simply requires a 5-minute initial unlock.
- HDD/SSD Compatibility & Restrictions (Except SKU: DS036): > Please note that ALL our software hard drives are designed as internal drives and CANNOT be used via a external USB enclosure, with the sole exception of SKU: DS036(Alldat* software). Before purchasing, please ensure the physical size and interface (e.g., 2.5″ SATA) of our drive are fully compatible with your laptop’s internal slot. If you are unsure about compatibility, please contact our customer support before buying.
- Pre-installed software HDD/SSD Warranty Void Policy: > Our pre-installed software contains encrypted configurations. Any attempt to duplicate, clone, or copy the files from our hard drive to another device will permanently lock the software and instantly VOID your product warranty. We do not provide after-sales support or refunds for drives that have been privately copied.
- Professional Remote Tech Support (Optional & Secure): > Automotive diagnostic software setup can be complex. We offer 100% free, secure remote technical assistance via TeamViewer to help you configure the system. This service is entirely optional. We respect your data privacy and will only perform necessary software configurations with your permission.

Great purchase!
Everything about this unit AL539B is great. If you are your own mechanic this unit will do everything you need.
Kemone –
Great tool for purchasing a car or everyday repairs
I’ve used this to buy my most recent car and it was a great purchase. The first car I viewed had a pending code and the scanner picked it right up, even though the person claimed there should be no codes. The multimeter is also great for battery testing, fuse testing, as well as, the starter test and alternator test feature. It even picked up codes that were not causing a check engine light. I have not been able to see if AL539B can view when codes have been erased, but all in all it was a great buy and worth every penny.
frank g. –
Best scanner reader.
This is by far the best scanner I’ve ever used has everything you need I highly recommend getting this along with some accessory attachments.
Levi –
Easy to use and versatile
I’ve been able to use this code reader for numerous functions from pulled diagnostic trouble codes, testing batteries, and checking readiness monitors. Its a great value for the money given what it can do.
G Siles –
Works with 2004 Dodge Caravan SXT. Great Value
I bought this Autel 3 in 1 – OBD 2 scanner and couldn’t be more happy. My wife drives a 2004 Dodge Caravan SXT, and everytime she has a problem with it, she doesn’t know how to explain it. So instead of wondering and guessing I just bought this tool to find out myself. Of course, I DID MY RESEARCH to avoid comments like “this doesn’t work with my car” because as a buyer and car owner it’s your job to figure that out. Anyway this is a Great price/value tool and it came with all the cables and a bag. I didn’t have any issues like any other reviewer claiming missing items. (Pictures for reference). Frequent buyer tip, make sure that your item ships from AMAZON, regardless of your seller. I also added pictures of this tool doing what it’s supposed to do and that’s giving the diagnosis on my wife’s car. Btw I bought this with my own money and this is not a sponsored review. Just my honest opinion. I hope you find it helpful and be safe out there.
Matthew McDaniel –
Tim from astro auto repair was on the money
Best tool AL539B for the money.
BriB –
Quick and multifunctional
I initially bought this as a quick tool for watching I/M Readiness on test drives after repairs. I didn’t think I would use this AL539B as much as I actually do. I use it to test the battery as part of the inspection attached to every oil change that enters my bay. I use it as a quick peek code reader. I use it for live data during diagnostics because I can change the units to values that match to the manufacturers scale instead of just my locals generic scale. I use the multimeter to check fuses and power feeds to sensors even though I have several other DMMs to choose from because it’s already in the service cart and ready to go. The only things I wish this tool did that it does not is test voltage drop (or amp load) during cranking and test alternator output amperage. It’s not designed to handle the amperages associated to those tests but that is ok because it does plenty more.
Kindle Customer –
Great tool, quick startup and ready to use.
I’m a professional auto technician, this tool is great, it’s faster to connect to just grab diagnostic trouble codes or check I/M status, just remember with any diagnostic tool it does not tell you exactly what’s wrong it is an aid to help you find the source or the problem. No tool in the market can tell you exactly what’s wrong it takes some leg work on your end.
Betty J. Davis –
Have used meters for troubleshooting all my life… Here is a great little meter!!!
All likes No dislikes!! A GREAT meter AL539B for automotive troubleshooting and all the other features built in are a real plus plus. I was told by Autel… this meter was NOT intended for the US market… better grab one before they are gone!!
Brandon Volturno –
Works great, multi use reader
Screen is bright and easy to see, it’s intuitive to use, and is multi function. Battery tester very useful with its cold cranking amps testing function, a voltmeter is handy for several uses, and of course the OBDII function works well also. It’s able to read codes and also tells you what the code means on the same screen, erases the codes, and can also show you live data of many different things.
