Launch X-431 Pro Dyno | Diagnostic Tool | Car

The Launch X-431 Pro3 Dyno is an advanced and powerful OE-level diagnostic solution, specifically designed for modern and universal workshops servicing a wide range of vehicle manufacturers. As the successor to the successful X-431 V4.0, this Apex version features enhanced hardware and faster software, combining comprehensive system diagnostics, online coding and over 30 maintenance functions in one robust platform. At the heart of the system is a fast 10.1-inch Full HD touchscreen tablet running the stable Android 10 operating system, enabling technicians to work efficiently on fault diagnosis, system adjustments and advanced vehicle configuration.

Wireless communication is handled by the new Launch DBScar VII VCI, a compact and powerful interface compatible with the latest communication protocols such as CAN-FD and DoIP. This ensures a stable and fast connection with the most modern vehicles on the market. The Pro3 Apex comes standard with two years of free software updates, including access to a rapidly expanding vehicle coverage of over 110 manufacturers worldwide. After this period, the system remains fully functional with the last installed software, but an annual licence is required to receive updates and use online functions.

Diagnostic functions:

The Launch X-431 Pro3 Apex offers comprehensive OE-level diagnostic capabilities, suitable for professional fault analysis, system communication checking and live monitoring of vehicle data.

• Full system diagnosis (OE-Level): Provides access to all electronic control units in the vehicle, such as engine, transmission, ABS, airbag (SRS), body control module (BCM), air conditioning, steering, instrument cluster and more. Supports reading and clearing fault codes with detailed descriptions.
• Intelligent topology mapping: Visualises the complete network of ECUs in an interactive module map. Communication status is clearly displayed with colour coding, allowing faults in, for example, the CAN-bus to be quickly and precisely identified.
• Active tests (bidirectional control): Sends commands to actuators, relays and components to test their operation without disassembly. Examples include controlling the fuel pump, activating the air-conditioning clutch, or testing the windscreen wiper motor.
• Live datastream: Displays real-time sensor data from modules in text format, graph view or as analogue gauges. Supports simultaneous display of multiple datastreams for thorough system comparison and fault diagnosis.
• AutoVIN: Automatically recognises the vehicle via the chassis number (VIN) and automatically selects the correct manufacturer, model and year of manufacture. This saves time and prevents errors in manual selection.

Maintenance and service functions:

The Launch X-431 Pro3 Apex supports over 40 maintenance and reset functions, allowing vehicle systems to be calibrated, reset or reconfigured after maintenance or component replacement. Suitable for universal workshops and dealer-level servicing.

• Oil service reset (Service): Resets the maintenance interval and extinguishes the service lamp after an oil change.
• Electronic parking brake (EPB): Release, close and initialise the electronic handbrake for safe brake servicing.
• Battery management system (BMS): Registers a new battery and restores the vehicle's charging strategy.
• Steering angle sensor (SAS): Calibrates the steering angle sensor after wheel alignment or replacement of steering components.
• Diesel particulate filter (DPF): Initiates forced regeneration of the soot filter and clears related fault codes.

• System language change: Modifies language settings on the vehicle display or infotainment system.
• Air/fuel ratio reset (A/F): Restores adaptive values for mixture control after sensor replacement or adjustment.

Programming and coding functions:

The Launch X-431 Pro3 Apex offers powerful coding capabilities for adapting, configuring and learning vehicle modules. This allows technicians to optimise vehicle systems or correctly activate new components according to OE specifications.

• Advanced ECU coding: Provides the ability to recode electronic control units, correctly configure new modules and activate hidden functions, such as disabling start/stop, coming-home lighting, or automatic mirror folding.
• Online coding: Supports direct connection to the factory servers of Volkswagen, Audi, BMW and Porsche, with coding data automatically loaded for the most accurate module configuration.
• Guided functions (VAG): For vehicles from the Volkswagen Group (VW, Audi, Seat, Skoda), the system provides step-by-step instructions for complex tasks such as key coding, steering module replacement, or ABS reprogramming, minimising the risk of errors.
• Important limitation: The Pro3 Apex does not support full ECU programming (flashing) with the standard DBScar VII VCI. For J2534 Pass-Thru ECU programming via OEM software, the optional Launch SmartLink C VCI is required.

Cloud and reporting functions:

The Launch X-431 Pro3 Apex supports powerful cloud and reporting tools for efficient workshop administration, customer communication and documentation of performed diagnostics.

• Cloud storage & management: All diagnostic reports are automatically saved to Launch Cloud, allowing them to be centrally managed, safely backed up and accessed at any time from multiple devices.
• Professional reports: Generates clear pre-scan and post-scan reports, which can be personalised with workshop logo, customer information and notes. Ideal for transparent customer communication and insurance documentation.
• Easy sharing and printing: Reports can be shared directly from the tablet via email or printed wirelessly over Wi-Fi, without requiring a PC or additional software.

Additional features and special capabilities:

The Launch X-431 Pro3 Apex is designed as a powerful and future-proof diagnostic platform, equipped with technologies and features that far exceed standard fault code readers.
