Launch X431 PRO3S+ Elite Bidirectional Diagnostic Tool with Smartlink 2.0 Support Topology Map Online Coding

The Launch X431 PRO3S+ Elite is designed for professional mechanics, automotive technicians, auto electricians, diagnostic specialists, independent workshops and multi-brand repair centers that require more than conventional OBD diagnostics. Its combination of full-system diagnosis, bidirectional Active Tests, topology mapping, online ECU coding, SmartLink C 2.0, CAN FD, DoIP, J2534, remote diagnostics and extensive expansion options makes it a versatile professional workshop platform.

The PRO3S+ Elite features a 10.1-inch 1280 × 800 display, Android 10, 2.0 GHz quad-core processor, 4 GB RAM, 64 GB storage, 8 MP rear camera and 6300 mAh battery. It communicates with the SmartLink C interface via Bluetooth/USB.

Yes. Commercial/heavy-duty vehicle diagnostics can be added using the appropriate Launch heavy-duty software, hardware and adapters. This makes the PRO3S+ Elite suitable for workshops that want to expand beyond passenger-car diagnostics.

Yes. The platform is highly expandable. Optional compatible accessories include X-PROG3 IMMO Programmer, Key Programmer, i-TPMS/TSGUN, BST360 battery tester, O2-series Scopebox, S2-2 Sensorbox, videoscope and ADAS equipment, among other professional Launch modules. These accessories are normally purchased separately.

Yes. The platform supports security-gateway solutions for selected manufacturers, including supported FCA, Renault, VAG and European Mercedes-Benz applications. Access can require separate licenses, accounts or subscriptions depending on manufacturer and region.

Depending on vehicle compatibility, functions can include Oil Reset, EPB service, SAS calibration, BMS functions, ABS Bleeding, DPF Regeneration, Injector Coding, Throttle Adaptation, gearbox-related procedures and numerous other maintenance, reset, relearn and calibration functions.

Yes. Current PRO3S+ Elite specifications list support for J2534, D-PDU and RP1210, further expanding its professional communication capabilities.

Yes. SmartLink C provides advanced remote diagnostic capabilities. This can allow supported remote diagnostic workflows and collaboration between technicians when appropriate network and service requirements are met.

Yes. Current PRO3S+ Elite specifications list support for J2534, D-PDU and RP1210, further expanding its professional communication capabilities.

Yes. The PRO3S+ Elite with SmartLink C supports J2534 Pass-Thru functionality for compatible OEM PC-based diagnostic/programming applications. Manufacturer software, subscriptions and authorization may be required separately.

Yes. DoIP (Diagnostics over Internet Protocol) is supported through SmartLink C 2.0 for compatible Ethernet-based vehicle diagnostic systems.

Yes. SmartLink C 2.0 supports CAN FD as well as conventional CAN 2.0 communication, allowing the PRO3S+ Elite to communicate with many newer vehicle electronic architectures.

SmartLink C 2.0 is the professional Vehicle Communication Interface supplied with the PRO3S+ Elite. It connects the diagnostic tablet to the vehicle and supports advanced communication protocols and remote diagnostic capabilities.

Not as a standard built-in function. Current comparisons distinguish ECU-Codierung from ECU Programming and state that the PRO3S+ Elite does not provide the built-in BMW/Mercedes online programming capability offered by the higher-level PRO5 platform.

Yes. Online coding is available for supported manufacturers and control modules. Exact online functionality depends on the vehicle brand, model, ECU, region and current Launch software coverage.

Yes. ECU coding is supported for compatible vehicles and modules. Depending on the manufacturer, available functions can include coding, adaptations, matching, personalization, configuration and selected online coding procedures.

Topology mapping provides a visual representation of the vehicle’s electronic control-module network. Instead of opening each system individually, technicians can view the network structure and quickly identify modules reporting faults or communication problems.

Yes. Bidirectional control allows the scanner to send commands directly to supported ECUs and actuators. This helps technicians test components independently and determine whether a problem is related to the component, wiring or control system.

Yes. It can access supported electronic control modules throughout the vehicle to read and clear DTCs, retrieve ECU information, display live data and perform available diagnostic, coding, adaptation and service procedures.

The Launch X431 PRO3S+ Elite is a professional automotive diagnostic scanner designed for workshops and advanced technicians. It combines full-system diagnostics, bidirectional Active Tests, ECU coding, topology mapping, service functions and modern vehicle communication protocols with the SmartLink C 2.0 VCI.
