Launch X431 SmartLink C 2.0 – Heavy Duty Diagnostic Module for Trucks and Construction Machinery (2026)

The Launch X431 SmartLink C 2.0 Heavy Duty is designed for professional truck mechanics, diesel technicians, commercial vehicle workshops, fleet maintenance companies, construction machinery technicians, agricultural equipment workshops, bus service centers, and diagnostic specialists. When combined with a compatible Launch X431 tablet and heavy-duty software, it provides a versatile professional platform for diagnosing a wide range of commercial and heavy-duty vehicles.

No. Vehicle identification, full-system diagnostics, Active Tests, special functions, CAN FD, DoIP, J2534, and other capabilities depend on the manufacturer, vehicle or machine model, production year, engine, ECU, diagnostic protocol, connector, software package, and current Launch coverage. Compatibility should always be checked for the specific application.

The SmartLink C 2.0 uses a dual-processor architecture with Cortex-A7 and Cortex-M7 processors and runs on Linux. It features a 320 × 480 display, 8 GB of storage, 256 MB of memory, less than 6W power consumption, and Wi-Fi, Bluetooth, and Ethernet communication.

The SmartLink C 2.0 Heavy Duty operates from approximately 9V to 36V DC. This wide operating-voltage range makes it suitable for both conventional vehicle electrical systems and 24V heavy-duty commercial vehicle applications.

SmartLink C is designed with remote diagnostic capabilities and can function as a remote J2534 Pass-Thru interface in supported configurations. Availability of remote services can vary by country, region, account, software version, and Launch service availability.

Yes. SmartLink C 2.0 can operate as a local J2534 Pass-Thru device for compatible applications. J2534 functionality can be used with supported PC-based software and workflows where the appropriate manufacturer software, licenses, subscriptions, and access permissions are available.

Yes. DoIP (Diagnostics over Internet Protocol) is supported for compatible applications. This allows SmartLink C to communicate with supported vehicles using Ethernet-based diagnostic architecture.

Yes. SmartLink C is designed to support CAN FD communication for compatible applications. CAN FD provides higher data-transfer capability than conventional CAN and is used in many newer vehicle electronic architectures.

Yes. Launch heavy-duty software includes diagnostic coverage for selected bus manufacturers and systems. Available coverage includes supported applications from manufacturers such as Setra, Neoplan, King Long, Yutong, Higer, Sunwin, Sunlong, Zhongtong, and others.

Launch heavy-duty software includes selected applications for manufacturers and systems such as Mercedes-Benz trucks, MAN, DAF, Mack, Kenworth, Hino, Renault Trucks, Sinotruk, FAW, JAC, Hyundai Heavy Vehicle, UD/Nissan Diesel, and others. Exact model and system coverage should be checked before purchase.

Launch heavy-duty software coverage includes selected systems from manufacturers such as Cummins, Bosch, Weichai, Shangchai, Yuchai, Xichai, Chaochai, Yangchai, Quanchai, and many others. Coverage varies according to the specific engine and control system.

Yes. Special diagnostic and service functions are available for supported heavy-duty vehicles. Exact functions depend on the manufacturer, vehicle, engine, ECU, and Launch software coverage.

Yes. Actuation or Active Tests are available for compatible vehicles and control systems. These tests allow technicians to command supported components directly through the diagnostic software to verify their operation.

Yes. Live data or data-stream reading is available for supported systems. Technicians can monitor available sensor values, operating parameters, temperatures, pressures, engine information, and other ECU data during troubleshooting.

Yes. The module can read and clear Diagnostic Trouble Codes (DTCs) from supported heavy-duty electronic control modules. This helps technicians identify faults and clear stored codes after the underlying problem has been diagnosed and repaired.

Yes. Full-system fault diagnosis is available for supported vehicles. Functions can include reading and clearing fault codes, viewing live data streams, performing special functions, and carrying out actuation tests on compatible electronic systems.

Yes. Construction machinery diagnostics are supported for compatible equipment. Available functions and system coverage depend on the machinery manufacturer, model, engine, ECU, diagnostic connector, and installed Launch software.

Depending on software coverage, the SmartLink C 2.0 Heavy Duty can be used with supported trucks, buses, construction machinery, agricultural machinery, trailers, commercial vehicles, and other heavy-duty applications.

No. The SmartLink C 2.0 Heavy Duty is not a standalone diagnostic scanner. It must be used with a compatible Launch X431 diagnostic tablet and the appropriate heavy-duty diagnostic software.

The Launch X431 SmartLink C 2.0 Heavy Duty is a professional vehicle communication and diagnostic module designed to expand compatible Launch X431 diagnostic tablets for heavy-duty and commercial vehicle applications. It supports diagnostics for compatible trucks, buses, construction machinery, agricultural machinery, trailers, and other heavy-duty vehicles.
