In detail: Autel MaxiSys Ultra compare Autel MaxiSys MS908S Pro


  1. Most advanced system diagnostic tool: Autel MaxiSys Ultra

Autel MaxiSys Ultra have more functionalities, so it is highly recommended for advanced system diagnostic tool.


Both MaxiSys Ultra and MaxiSys MS908S Pro scanners support OE-level system

diagnostics. You can read trouble codes from all modules for 90% of OBD2-compliant vehicles. We are talking more than engine, airbag, ABS and transmission. You can also look at all the systems in your vehicle, including the SRS, TMPS, EPB, etc.

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

Also, both scanners perform intelligent diagnostics. When you insert the scanner, they 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.


  1. Advanced service Reset functions

Autel MaxiSys MS908S Pro can perform 30+ advanced service functions, Autel MaxiSys Ultra offers up to 36 advanced service functions.


Both scanner allow you to access standard reset features. These include oil lamp reset, injector coding, electronic parking brake reset, steering angle calibration, ABS bleeding, TPMS reset,  etc.


However, 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.


  1. Bi-directional controls

Both Autel MaxiSys MS908S Pro and Autel MaxiSys Ultra scanners have bidirectional functionality. It means you can perform active tests on various systems and modules. But the specific systems supported are dependent on the vehicle make and model.


  1. Coding/Programming

ECU Coding function allows you to update the computer software on the vehicle to the latest version, recode adaptive data for certain components after making repairs or replacements to improve driving performance, fuel efficiency and reduce power loss. Available coding operations vary by the test vehicle, and only the available operations display in the menu.


Autel MaxiSys MS908S Pro ECU Programming applies to BMW & Benz vehicles ONLY. ECU Coding is NOT universally compatible. Please check compatibility with us before purchase.


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.


  1. Specialties

First, both MaxiSys MS908S Pro and MaxiSys Ultra scanners are excellent all system diagnostics tools. Autel MaxiSys MS908S Pro offers many similar functions to the MaxiSys Ultra. Only that, it cannot pair with the 5-1 VCMI.


Autel MaxiSys Ultra: 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. If you need these functions, the MaxiSys Ultra model is the ideal choice for your needs.


  1. Vehicle coverage

In terms of full-system OBD2 diagnostics, Both Autel MaxiSys Ultra and MaxiSYS MS908S Pro scanners support 80+ car brands from domestic US car brands, to European and Asian vehicles. The difference comes in programming and coding, as discussed above.


Bothe are highly recommended for BMW and Mercedes beside tens of other brands.


  1. Compatible protocols
