OE-Level Full-System Vehicle Diagnostics
The Autel MS919 S2 provides comprehensive diagnostic access to major electronic control modules on supported US, Asian and European vehicles.
Diagnostic capabilities can include:
- Automatic full-vehicle scanning
- Read and erase diagnostic trouble codes
- ECU information
- Freeze-frame data
- Live data and graphing
- Vehicle health reports
- Pre-scan and post-scan reports
- Active tests
- Coding and adaptations

Technicians can diagnose systems including engine, transmission, ABS, SRS, body control, steering, chassis, HVAC, battery management, parking brake and additional available modules.
ECU Programming, Coding & Adaptations
The Autel MaxiSys MS919 S2 is designed for workshops handling advanced module replacement, coding and programming procedures.
Through the MaxiFlash VCMI2, the scanner supports J2534 pass-thru programming, enabling compatible OEM programming procedures when used with the required manufacturer software and subscriptions.
Depending on vehicle support, ECU-related functions can include:
- ECU coding
- Module adaptations
- Variant configuration
- Component matching
- Personalized vehicle settings
- Replacement module setup
- Vehicle-specific special programming procedures
Bi-Directional Control & Active Tests
Bi-directional control allows technicians to send commands directly from the MS919 S2 to supported vehicle modules and components, helping confirm whether a component can respond correctly before replacing parts.
Active tests may include:
- Radiator and cooling fan activation
- Fuel pump operation
- Injector testing
- Exterior and interior lighting
- A/C clutch operation
- Relays and solenoids
- Electronic parking brake operation
- Windows and door locks
- HVAC actuators
- Additional vehicle-specific component tests
This capability helps workshops move beyond simply reading fault codes and perform more accurate component-level diagnosis.
Topology 3.0 Dynamic Network Analysis
Topology 3.0 provides an OE-style visual representation of the vehicle communication network. Instead of viewing ECUs only as a conventional list, technicians can see how supported control modules and communication networks interact.
Color-coded module status makes it easier to identify faults, modules with communication issues and systems that are not responding.
Dynamic network analysis also enables supported modules to be pinged and monitored, helping diagnose network integrity and signal-quality problems.
Smart PID Data Analysis
The MS919 S2 introduces enhanced data-driven diagnostics designed to make live-data analysis faster and easier.
Technicians can:
- Visualize multiple parameters using advanced graphs
- Record and compare live-data trends
- Analyze related PIDs simultaneously
- Compare values across different systems
- Identify relationships between sensor parameters
- Use real-time split-screen analysis
These functions can help diagnose engine performance, emissions problems, intermittent faults and complex electronic issues where a single PID alone does not provide enough information.
Real-Time Split-Screen Diagnostics
Split-screen functionality enables technicians to view different diagnostic applications simultaneously rather than repeatedly switching between screens.
Useful combinations can include:
- Live Data + Oscilloscope
- Fault Scan + Network Analysis
- Topology + Component Location
- Topology + Diagnostic Trouble Codes
This improves workflow when diagnosing complicated faults that require comparison between electronic signals, live data and network information.
MAX Hands-Free Voice Assistant
The integrated MAX virtual assistant provides hands-free navigation and voice-control capability for supported scanner operations.
Technicians can use voice commands to:
- Start system scans
- Access maintenance functions
- Perform supported active tests
- Navigate the diagnostic interface
- Receive operation guidance
6-in-1 MaxiFlash VCMI2
The upgraded MaxiFlash VCMI2 turns the MS919 S2 into much more than a standard OBD diagnostic scanner.
The VCMI2 combines:
- Vehicle Communication Interface
- J2534 Pass-Thru Programmer
- 4-Channel Automotive Oscilloscope
- Digital Multimeter
- Waveform Generator
- CAN Bus Tester
It can also operate as a standalone Remote Expert device for supported remote diagnostic and programming services.
Enhanced 4-Channel Automotive Oscilloscope
The integrated 4-channel oscilloscope provides professional electrical testing capabilities for sensors, actuators, communication circuits and other vehicle electrical systems.
The oscilloscope can be launched directly while analyzing live data, allowing technicians to compare ECU data with real electrical waveforms.
Typical applications can include:
- Sensor signal diagnosis
- Actuator waveform testing
- Ignition analysis
- CAN network signal testing
