Key Features & Performance
The Autel Maxisys Ultra’s reputation is built on a foundation of powerful features. In my testing, these features translated into tangible performance benefits that justify its position in the professional market.
Comprehensive Vehicle Coverage and System Access
This is the cornerstone of the Ultra’s appeal. It supports an enormous range of vehicles, including Asian, European, and domestic passenger cars, as well as light/medium-duty trucks and many electric vehicles. More importantly, it provides deep-level access to virtually every electronic control unit (ECU) in the vehicle. I was able to not only read codes from the engine or transmission but also access systems like airbags, ABS, steering angle sensors, parking assist modules, and infotainment units. The ability to perform active tests—activating solenoids, relays, and motors directly from the tool—was invaluable for pinpointing faults without disassembling components.
Advanced Programming and Coding Capabilities
For modern diagnostics, the ability to code and program modules is often non-negotiable. The Maxisys Ultra handles this with authority. It supports both offline coding (using data stored on the device) and online programming for the latest software flashes, the latter requiring an Autel Security Access subscription. In my use, functions like programming a new key fob, adapting a throttle body, or coding a replacement control module worked smoothly. The guided processes are clear, and the tool provides important warnings and battery voltage checks to prevent errors during critical programming events, which is a crucial safeguard.
Integrated Repair Information and Guided Functions
Beyond raw data, the Ultra includes a wealth of technical repair information directly on the device. This includes wiring diagrams, component locations, maintenance schedules, and technical service bulletins (TSBs). The guided functions are particularly impressive. For example, when working on a brake bleed procedure for a vehicle with electronic stability control, the tool can guide you through the specific steps required to activate the pump and solenoid via the ABS module. This integration of data and direct vehicle control saves significant time compared to juggling a separate manual or subscription service.
Robust Hardware and Wireless Operation
Performance is also about the physical experience. The tablet itself feels solid and well-built. The screen is responsive and bright, even when used under shop lights. The wireless VCI is a game-changer for convenience; you can connect it to the vehicle’s OBD2 port and then freely use the tablet anywhere within range—inside the car, under the hood, or at the wheel during a test drive. This eliminates the hassle of a cable and reduces the risk of damaging the port or the tablet. The battery life is sufficient for a full day’s work, and the device charges quickly.

I wholeheartedly recommend the Autel Maxisys Ultra for its intended audience: professional automotive repair shops, fleet maintenance departments, and highly skilled technicians. It is a tool that pays for itself by expanding service offerings and solving difficult problems faster. However, for the average home mechanic or someone who only needs occasional basic code reading, this tool is excessive. Its complexity and focus are squarely on professional use. If you fall into the professional category and need one device to do almost everything, the Maxisys Ultra is a compelling choice that stands up to rigorous daily use.
