Which cars this scanner actually covers
The Autel AL549 works as a general OBD2 code reader and adds ABS code reading and clearing. It also tests your starting and charging system, so it can flag a battery or alternator issue before you guess at parts.
Compatibility is where this purchase is won or lost. The ABS side only supports OBD2 standard vehicles built before 2020, so if your car is a 2020 or newer model, we'd skip it for ABS work. You should confirm the ABS function covers your specific year and model before ordering, because the listing names major North American, European and Asian brands without pinning down every trim.

What it will not do
This is a diagnostic reader, not a repair tool. It reads and erases codes, shows live data, freeze frame and vehicle information, and provides code definitions, but it does not fix the underlying fault or guarantee a vehicle is safe to drive.
The ABS coverage stops at pre-2020 OBD2 vehicles. If you drive a newer car, plan on using the OBD2 side only and check that the enhanced powertrain coverage for Ford, GM and Chrysler matches your vehicle.
Reads and clears ABS codes on pre-2020 OBD2 vehicles, plus standard OBD2 codes.
Does not repair faults or substitute for a proper diagnosis.

At $55.20, you are paying $13.25 less than a typical price over the last 90 days of $68.45. That is about 19 percent off, and $55.20 is the lowest price on record for this scanner.
For a tool that covers OBD2 codes, ABS codes and a battery test, that is a fair entry point if the compatibility checks line up.
Power, printing and update checks
The scanner runs from your car's OBD2 port, so you do not need a separate power source for basic use. For battery and alternator testing, follow the on-screen guidance and the pretest steps in the user manual, because results depend on doing those steps in order.
Printing requires a Windows-based PC and the supplied USB cable, so confirm you have that setup if paper reports matter to you. Updates come through the Maxi PC Suite on a PC, which is worth checking against the computer you actually own.
Who should buy this scanner
Buy it if you own a pre-2020 OBD2 vehicle, want to read and clear ABS and check-engine codes yourself, and want a basic battery and charging system check in the same handheld. The $55.20 price makes it a reasonable first diagnostic tool for that job.
Skip it if your ABS work is on a 2020 or newer car, or if you need manufacturer-specific coverage beyond the powertrain codes listed for Ford, GM and Chrysler. Check your vehicle year and the ABS brand list one last time before you order.
