Launch X431 PRO3 APEX – Professional OBD2 Diagnostic Scanner

The Launch X431 PRO3 APEX is a professional automotive diagnostic scanner designed for workshops, mechanics, auto electricians, and advanced diagnostic technicians. It combines all-system diagnostics, bi-directional Active Tests, ECU Coding, Topology Mapping, 37+ service functions, CAN FD, DoIP, and wireless DBScar VII communication in one 10.1-inch diagnostic platform.

Yes. The PRO3 APEX provides OE-level all-system diagnostics on supported vehicles. It can access electronic systems such as Engine, Transmission, ABS, SRS/Airbag, BCM, TPMS, Steering, HVAC, EPB, Chassis, and many other available control modules.

On supported vehicles, the PRO3 APEX can read and clear Diagnostic Trouble Codes (DTCs), retrieve ECU information, display live data, perform automatic system scans, execute Active Tests, and access vehicle-specific diagnostic and service functions.

Yes. The PRO3 APEX provides bi-directional control, also known as Active Tests. This allows technicians to send commands directly to supported ECUs and actuators to verify whether individual components are operating correctly.

Available Active Tests vary by vehicle and can include fuel pump activation, injector tests, cooling fan operation, A/C clutch activation, windows, doors, lights, wipers, valves, solenoids, and other electronically controlled components. Exact availability depends on the vehicle and ECU.

Yes. The PRO3 APEX supports advanced ECU Coding on compatible vehicles. Depending on the manufacturer, coding can be used for module matching, component replacement, adaptive data configuration, personalization, and modification of supported factory settings.

Yes. Online Coding is available for selected supported vehicle manufacturers. The function can access online coding data for compatible vehicles and modules. Coverage varies according to manufacturer, model, year, ECU, region, and current Launch software.

Yes. Topology Mapping is one of the key advanced features of the PRO3 APEX. It provides a visual representation of the vehicle’s ECU communication network, helping technicians quickly identify modules with faults or communication problems.

Instead of checking every control module individually, Topology Mapping provides an overview of supported ECUs and their communication relationships. This makes it easier to identify faulty modules, locate communication errors, and enter individual ECUs for further diagnosis, helping reduce diagnostic time.

The PRO3 APEX provides 37+ service, reset, adaptation, and maintenance functions. Exact availability varies according to the vehicle manufacturer, model, model year, ECU, and installed diagnostic software.

Depending on vehicle compatibility, available functions can include Oil Reset, EPB Reset, SAS Calibration, BMS Reset, ABS Bleeding, DPF Regeneration, Injector Coding, Throttle Adaptation, TPMS-related functions, Gear Learning, EGR Adaptation, Suspension Calibration, AdBlue Reset, and many other vehicle-specific procedures.

Yes. The included DBScar VII VCI supports CAN FD, allowing the PRO3 APEX to communicate with compatible newer vehicles using this high-speed communication protocol.

Yes. The DBScar VII also provides DoIP (Diagnostics over Internet Protocol) support for compatible vehicles. DoIP uses Ethernet-based communication and is increasingly used in modern vehicle electronic architectures.

The DBScar VII is the wireless Vehicle Communication Interface supplied with the PRO3 APEX. It connects to the vehicle’s diagnostic port and communicates with the tablet via Bluetooth. It also supports USB communication and modern protocols such as CAN FD and DoIP.

Yes. The PRO3 APEX supports authorized access to compatible FCA vehicles equipped with a Secure Gateway Module (SGW). An appropriate AutoAuth account and any applicable authorization or subscription fees may be required separately.

Yes. The PRO3 APEX can be expanded with the optional Launch X-PROG3 to provide additional immobilizer and key programming capabilities on supported vehicles. Exact IMMO functions depend on the vehicle, software version, and accessories being used.

Yes. The PRO3 APEX platform can be expanded for Heavy Duty truck and commercial vehicle diagnostics using compatible Launch Heavy Duty hardware and the required software package. This makes it possible to extend the scanner beyond standard passenger vehicle diagnostics.

Yes. The PRO3 APEX supports ADAS calibration when combined with compatible Launch ADAS calibration equipment. This allows workshops to expand the diagnostic platform for supported camera- and radar-based Advanced Driver Assistance System calibration procedures.

The PRO3 APEX features a 10.1-inch 1280 × 800 touchscreen, Android 10 operating system, 2.0 GHz quad-core processor, 4 GB RAM, 64 GB internal storage, 8 MP rear camera, 6300 mAh battery, and dual-band 2.4 GHz/5 GHz Wi-Fi. Vehicle communication is handled by the wireless DBScar VII VCI.

The Launch X431 PRO3 APEX combines all-system diagnostics, bi-directional Active Tests, ECU Coding, Online Coding, Topology Mapping, 37+ service functions, CAN FD, DoIP, FCA SGW access, and wireless DBScar VII communication in one professional platform. Its 10.1-inch display, 4 GB + 64 GB hardware, and expansion options for IMMO, ADAS, and Heavy Duty diagnostics make it a versatile solution for professional workshops that need advanced multi-brand diagnostic capabilities.
