Autel MaxiSys Ultra EV Functions

EVDiag Box & Adapters for Battery Pack Diagnostics

The EV Diagnostics Upgrade Kit includes an EVDiag Box and adapters with a carrying case for specific electric vehicles to perform battery pack analysis. The EVDiag Box is compatible with the MaxiSys Ultra, MaxiSys Ultra ADAS, MaxiSys MS919, and MaxiSys MS909 tablets, and connects to MaxiFlash VCI or VCMI.

• Includes EVDiag Box, Adapters for BMW, VW and Breakout Leads
• Includes Carrying Case
• Compatible with Ultra series products to perform Battery Pack diagnostics
• State of Charge and State of Health analysis for true battery condition
• For customers who already own MS909, MS919EV, or MaxiSys Ultra, purchasing the EV box alone upgrades their device to MS909EV, MS919EV, or MaxiSys Ultra EV.
• To activate the EV box on MS909/MS919/MaxiSys Ultra: input the EV box serial number directly into the tablet portal and select the EV Diagnostics Upgrade Kit.

High-Voltage Diagnostics

High-voltage system diagnostics allow for reading and clearing codes and displaying SOC, SOH, voltage, and battery pack status with one click—helping quickly locate faults. The Ultra EV provides a high-voltage system block diagram, parts diagram, plug-in diagram, and disassembly guide to simplify operation. The scan tool also supports offline battery pack diagnostics to ensure efficient completion of each battery installation.

Advanced 5-IN-1 VCMI

The VCMI integrated into the Autel MaxiSys Ultra combines five powerful functions: VCI, Oscilloscope, Waveform Generator, Multimeter, and CAN BUS CHECK—making it one of the most capable diagnostic tools available.

1. VCI Connection (Wi-Fi / BT / USB):
   Supports dual wireless mode. The host and communication box connect via Wi-Fi, offering faster transmission speed, greater stability, and strong anti-interference capability. Real-world tests show wireless range exceeding 50 meters and diagnosis speeds over 30% faster.
2. Oscilloscope:
   Integrated into the VCMI with four key technologies: large bandwidth, high sampling rate, deep storage, and massive preset cases. Supports zoom & playback and advanced triggering to improve complex fault resolution efficiency.
3. Waveform Generator:
   Supports multiple signal modes—including DC voltage, square wave, square wave (X+Y), triangle wave, actuator drive, and arbitrary waveform—to simulate sensor and ECU signals, enabling intuitive hardware issue identification without part replacement.
4. Multimeter:
   Measures voltage, current, resistance, frequency, diode status, duty cycle, pulse width, and connectivity.
5. CAN BUS CHECK:
   Detects OBD interface signals to quickly verify communication status. A flashing indicator light confirms normal signal; if no signal is detected, verify correct pin configuration.

New Topology Module Mapping

The new Topology Module Mapping feature displays a CAN BUS Tree—originally designed for OEM diagnostic tools—that shows all available control units of the test vehicle in color-coded format. This allows users to instantly identify the number of systems, which systems have been scanned, and the results of those scans.

Intuitively displays the current module status—including whether a specific module contains DTCs and the number of DTCs present.

Communication Structure & Vehicle Compatibility

Systematically visualize the communication structure between vehicle modules.
Directly display fault codes and access system execution functions.
Easily view the color-coded module status tree with zoom in/out functionality.
Compatible with a wide range of makes including BMW, Ford, Audi, Chrysler, Nissan, Honda, Toyota, Lexus, Land Rover, Jaguar, Mercedes-Benz, Volkswagen, and more.

ECU Programming & Coding

The Autel Diagnostic Scanner Ultra EV includes a J2534 ECU Programming device and a BMW Ethernet Cable (for F-Series coding and programming). It enables replacement of existing software/firmware in Electronic Control Units (ECUs), programming of new Mercedes-Benz and BMW ECUs, resolution of software-controlled drivability and emission issues, and updating of vehicle computer software to the latest version.
Note: ECU Programming is supported only for BMW and Mercedes-Benz vehicles.

Full Bi-Directional Control (Active Test)

The Autel MaxiSys Ultra EV automotive diagnostic scanner features full bi-directional control, allowing active tests to verify the integrity of systems or components such as ABS, windows, doors, and sunroofs. Technicians can read ECU data or monitor actuator operation—like switching solenoids or relays—to diagnose issues effectively.
Note: Available tests vary by vehicle manufacturer, year, and model. Only compatible tests appear in the menu. For vehicle-specific compatibility, refer to the Autel website or contact support directly.

40+ Advanced Service Functions

As Autel’s flagship diagnostic tool, the MaxiSys Ultra EV delivers over 40 powerful service functions—including resets, adaptations, and relearns—to resolve common issues such as Oil Reset, EPB, SAS, A/F Setting, Throttle Calibration, Suspension Reset, Headlamp Adjustment, Injector Coding, and Power Balance. Additionally, its bi-directional capabilities enable specialized active tests on components like the PCM, fuel injectors, ignition coils, fuel pump, and A/C clutch for rapid diagnostics. OE-level full-system diagnosis provides deep access to all available modules to identify and fix problems comprehensively.
Note: Service availability is not universal and depends on vehicle make, model, and year.
