LAUNCH X431 PRO3S+ SmartLink HD Heavy Duty Truck Diagnostic Tool
The LAUNCH X431 PRO3S+ SmartLink HD is a professional diagnostic tablet for commercial vehicles, combining the X431 PRO3S+ platform with the SmartLink C 2.0 heavy-duty module. Consequently, technicians can diagnose both 12V passenger vehicles and 24V trucks, buses, trailers and plant machinery with a single system.
2 years of software updates included.
Because modern commercial vehicles use many separate electronic control units, a dedicated heavy-duty connector is essential for reliable communication. The SmartLink HD module provides that access, while the X431 PRO3S+ tablet delivers fast processing, a large display and one-click Wi-Fi updates.
Professional Heavy-Duty Diagnostics
Heavy goods vehicles rely on multiple control units to manage engine, transmission, braking, ABS and aftertreatment systems. Therefore, technicians need equipment capable of communicating with each system and reporting accurate fault information. The LAUNCH X431 PRO3S+ SmartLink HD provides full-system fault diagnosis on supported vehicles, including fault code reading and clearing, live data streaming and component testing.
SmartLink C 2.0 Coverage
The SmartLink C 2.0 module supports newer communication protocols such as CAN FD, improving communication speed and coverage of later vehicle models. Depending on the software package, coverage extends to common diesel and commercial-vehicle systems, including trucks, buses, trailers, construction equipment and agricultural machinery.
