Look at the comparison table below:

Part 3. Autel MaxiSys Ultra in-depth Review

Highlights: 5-1 VCMI

Autel MaxiSys Ultra is an excellent all-system diagnostics tool, it wins Autel Elite / MS908S Pro in the 5-1 VCMI. You get a tool that comes bundled with a VCI that transforms it into a 4-channel oscilloscope, multimeter, CAN BUS tester, and waveform generator.

Most advanced system diagnostic tool

Autel MaxiSys Ultra is highly recommended for advanced system diagnostic tool because it can perform more functionalities.

MaxiSys Ultra is able to perform system diagnostics, including read trouble codes from all modules for 90% of OBD2-compliant vehicles. including but not limited to the engine, transmission, antilock brake system (ABS) and airbag system (SRS).

It can produce freeze frame data, powertrain diagnostic data, emission diagnostic data, emission diagnostic trouble codes, oxygen sensor monitoring test results, and onboard monitoring tests.

It can perform intelligent diagnostics. When you insert the scanner, it will automatically read the VIN information.

Autel MaxiSys Ultra supports topology mapping. This means they can check all systems communications and DTCs visually.

Meanwhile, with the MaxiSys Ultra, you can see two different functions since it supports split-screen multitasking. Furthermore, you can turn the MaxiSys Ultra into a 4-channel oscilloscope, waveform generator, CAN Bus Tester, and multimeter.

Advanced special functions

The Service section is specially designed to provide quick access to the vehicle systems for various scheduled service and maintenance tasks. The typical service operation screen is a series of menu driven executive commands. Follow on-screen instructions to select appropriate execution options, enter correct values or data, and perform necessary actions. The application will display detailed instructions to complete selected service operations.

After entering each special function, the screen will display two application choices: Diagnosis and Hot Functions. The Diagnosis enables the reading and clearing of codes which is sometimes necessary after completing certain special functions. Hot Functions consists of sub functions of the selected special function.

Autel MaxiSys Ultra offers up to 36 advanced service functions including oil lamp reset, injector coding, electronic parking brake reset, steering angle calibration, ABS bleeding, TPMS reset,  etc.

If you’re looking for repair advice, MaxiSys Ultra gives you detailed repair information and illustrations. It also includes an extensive waveform library, plus Oscilloscope preset guides.

Bi-directional controls

Autel MaxiSys Ultra scanner has bidirectional functionality, that means you can perform active tests on various systems and modules. But the specific systems supported are dependent on the vehicle make and model.

Coding & Programming

Autel MaxiSys Ultra can perform coding and programming for countless models including Online ECU programming on Benz and BMW models, online coding on VW/Audi, Seat, Porsche, Renault, and again, BMW and Benz models. For online ECU programming, MaxiSys Ultra can do so without special connectors on BMW F&G chassis. It can perform new chassis online programming and SCN on Benz.

The Programming and Coding function is used to re-flash the vehicle control modules, which allows you to update the computer software of the vehicle to the latest version, as well as to reprogram adaptive data of certain components after making repairs or replacements.

Note: The programming function applies only when the vehicle is connected with a VCMI device, which serves as a PassThru interface to establish communication with and transfer data to the vehicle’s ECU.

Available programming or coding operations vary by test vehicle. Only the available operations display in the tablet menu.

There are two general types of programming operations:

  1. Coding – also known as Teach-in Program, or Component Adaptation, is used toreprogram adaptive data for vehicle control modules after repairs or replacementsof vehicle parts.
  2. Reprogramming – downloads the latest version of software from the online serverdatabase through Internet access (this procedure is done automatically when thetablet is connected to the Internet, so there is no need to check for software updates yourself), and reprograms the newest version into the vehicle’s ECU.


Ensure that the tablet is connected to a stable internet access before applying the ECU programming function, so that the tablet is able to obtain access to the vehicle manufacturer’s server for update service.

Selecting the Programming or Coding function opens a menu of operation options that varies by vehicle make and model. Selecting a menu option either displays a programming interface or opens another menu of additional choices. Follow all screen instructions while performing the programming or coding operations. How and what information is presented on the screen vary by the type of operation being performed.
