The Autel MaxiSYS Ultra S2 is Autel’s most advanced professional diagnostic platform, designed to keep pace with increasingly complex vehicle electrical systems, hybrid vehicles and electric vehicles (EVs).
Building on the award-winning MaxiSYS Ultra, the Ultra S2 introduces the new MAX AI Assistant, Topology 3.0 dynamic network mapping, enhanced hardware performance and intelligent diagnostic features that help technicians diagnose faults faster and more accurately.
The Ultra S2 offers outstanding coverage for over 80 vehicle manufacturers, delivering OE-level diagnostics, 26+ service functions, ECU coding, programming, and advanced live data analysis on a large high-resolution display powered by Autel’s fastest processors and largest SSD storage. A docking station is included as standard.
The system combines diagnostics, servicing, ECU coding and reflashing with the latest MaxiFLASH VCMI, featuring a built-in 4-channel Oscilloscope, Multimeter, Signal Generator and OBD Bus Check. High-speed Wi-Fi communication provides faster and more stable connectivity between the tablet and the VCMI, while support for D-PDU, RP1210, CAN FD, J2534 and DoIP ensures compatibility with the latest vehicle communication protocols.
With intelligent software features including MAX AI Assistant, Topology 3.0, Repair Assist, DTC Analysis and Relevant Cases, the Ultra S2 provides technicians with faster fault identification, guided diagnostics and access to repair information, making it one of the most capable diagnostic platforms available today.
The MaxiSYS Ultra S2 can also be upgraded to operate Autel’s ADAS calibration systems, providing a complete workshop solution for diagnostics, calibration and programming.

- Pulse Width
OBD Bus Check
The integrated OBD Bus Check quickly verifies the condition of OBD communication pins and vehicle network integrity before diagnostics begin.
Communication Protocols
The supplied MaxiFLASH VCMI supports all major modern vehicle communication standards including:
- J2534 Pass-Thru
- DoIP (Diagnostics over IP)
- CAN FD
- RP1210
- D-PDU
Providing compatibility with current and future vehicle architectures.
Repair Assist
Repair Assist provides guided troubleshooting procedures with prioritised testing recommendations.
The software automatically recommends the most efficient repair path, identifies relevant wiring diagrams and pin locations, and allows technicians to follow or skip individual inspection steps where appropriate.
Currently supported for selected BMW, Jaguar Land Rover, GM, Ford, Chrysler and Porsche models.
Relevant Cases
Relevant Cases automatically recommends similar repair cases based on the vehicle and fault codes detected.
The system also provides access to manufacturer Technical Service Bulletins (TSBs), repair procedures, software update information and known vehicle issues to improve diagnostic efficiency.
Currently supported for selected Ford, GM, FCA, Toyota, Lexus, Volkswagen, Nissan, Honda, BMW, Mercedes-Benz, Audi, Hyundai and Kia vehicles.
DTC Analysis
DTC Analysis provides intelligent descriptions of fault codes, likely causes and recommended repair procedures to reduce diagnostic time and improve first-time fix rates.
Currently supported for selected GM, Ford and Toyota vehicles.
