Autel MaxiSys Ultra S2 – 2026 Advanced ECU Programming & OE-Level Diagnostic Scanner
The Autel MaxiSys Ultra S2 is a flagship professional automotive diagnostic platform engineered for workshops, diagnostic specialists, automotive electricians and technicians handling complex modern vehicles. It combines OE-level full-system diagnostics, ECU programming and coding capabilities, bi-directional control, advanced vehicle network analysis and professional electrical measurement into one powerful workshop system.
Built around a large 13.7-inch anti-glare touchscreen, Android 13, a 2.7GHz 8-core processor, 12GB RAM and 512GB of internal storage, the Ultra S2 is designed to handle demanding diagnostic workflows while allowing technicians to move quickly between scanning, live data, active tests, programming and repair information.
The upgraded MaxiFlash VCMI2, Topology 3.0, enhanced 4-channel oscilloscope, MAX voice assistant, Digital Vehicle Inspection and 48+ service functions make the Ultra S2 a complete diagnostic workstation for advanced professional workshops.
OE-Level Full-System Diagnostics
The Autel MaxiSys Ultra S2 provides comprehensive access to electronic systems throughout supported vehicles, allowing technicians to perform complete diagnostic scans and investigate faults across multiple ECUs.
Supported diagnostic operations can include:
- Read and erase diagnostic trouble codes
- View ECU information
- Display and graph live data
- Access freeze-frame information
- Perform complete vehicle Auto Scan
- Run system and component active tests
- Perform adaptations and special functions
- Generate diagnostic and vehicle health reports
Coverage can include engine, transmission, ABS, SRS, body control, chassis, steering, HVAC, battery management, electronic parking brake, instrument systems and additional available modules.
ECU Programming, Coding & Adaptations
For workshops dealing with module replacement and advanced electronic repairs, the Ultra S2 combines ECU coding and adaptation capabilities with J2534 pass-thru programming through the MaxiFlash VCMI2.
Depending on vehicle support, technicians can perform coding, component adaptations, variant configuration and other module-specific operations required following replacement or repair.
The VCMI2 can also be used with compatible OEM software for J2534 pass-thru programming, providing professional workshops with a more complete solution for modern ECU service requirements.
Bi-Directional Control & Active Tests
The Ultra S2 supports bi-directional control, allowing the diagnostic tablet to send commands directly to supported vehicle control modules.
Depending on the vehicle, active tests may include:
- Fuel pump activation
- Injector testing
- Cooling fan operation
- Solenoid activation
- Electronic parking brake testing
- Door lock and window operation
- Lighting tests
- HVAC actuator operation
- Relay activation
- Other supported actuator and component tests
Active testing helps technicians isolate component, wiring and control-module faults faster than relying on diagnostic codes alone.
Topology 3.0 Dynamic Network Analysis
One of the strongest diagnostic features of the Autel Ultra S2 is Network Topology 3.0. It provides an OE-style visual representation of the vehicle communication network, allowing technicians to understand the relationship between modules and networks at a glance.
Color-coded module status helps quickly identify faults, communication problems and modules that are not responding.
Topology 3.0 also supports active module and network analysis, allowing technicians to locate and directly ping ECUs to evaluate signal quality and network integrity.
6-in-1 MaxiFlash VCMI2
The upgraded MaxiFlash VCMI2 transforms the Ultra S2 from a diagnostic tablet into a complete vehicle communication, programming and electrical measurement platform.
The 6-in-1 VCMI2 combines:
- Vehicle Communication Interface
- J2534 Pass-Thru Programmer
- 4-Channel Oscilloscope
- Digital Multimeter
- Waveform Generator
- CAN Bus Tester
It can also function as a standalone Remote Expert device, helping professional workshops access additional programming and diagnostic support when required.
Enhanced 4-Channel Oscilloscope
The VCMI2 includes an improved four-channel automotive oscilloscope for advanced electrical and electronic troubleshooting.
Technicians can launch the scope directly while analysing live data, making it easier to compare ECU parameter information with actual electrical signals.
Diagnostic applications can include:
- Sensor and actuator waveform testing
- Ignition analysis
- Communication signal analysis
- Charging system testing
- Parasitic current testing

Advanced Live Data & PID Analysis
The Ultra S2 provides enhanced live-data visualization for technicians diagnosing increasingly complex vehicle systems.
Multiple parameters can be viewed and graphed to identify abnormal sensor readings, intermittent problems and relationships between vehicle systems.
Reference sampling can also help technicians compare selected PID values before and after repairs, including minimum, maximum and average readings.
MAX Hands-Free Voice Assistant
The integrated MAX virtual assistant allows technicians to control supported Ultra S2 functions using voice commands.
MAX can help launch system scans, access maintenance functions and initiate supported active tests without repeatedly navigating through the tablet interface, which can be useful when the technician is physically working on the vehicle.
Advanced Digital Vehicle Inspection
The Ultra S2 includes advanced multi-point Digital Vehicle Inspection capabilities designed to help workshops document vehicle condition and provide customers with clearer inspection information.
The system can help organize inspection results and can be integrated into a broader professional vehicle inspection workflow.
EV-Ready Diagnostics
Modern electric and electrified vehicles require increasingly advanced electrical testing capabilities. The Ultra S2 provides enhanced diagnostic and measurement functions for supported EV and high-voltage applications.
Available electrical testing capabilities can include:
- AC and DC charging system analysis
- High-voltage component testing
- Interlock loop signal testing
- Power-on control analysis
- Resolver sensor testing
- Thermal management system analysis
DoIP, CAN FD, J2534 & D-PDU Support
The Ultra S2 supports modern vehicle communication protocols required by many newer European, Asian and American vehicle platforms.
- DoIP
- CAN FD
