XTOOL D9HD – Professional 12V & 24V Heavy-Duty Diagnostic Tool
The XTOOL D9HD is a professional dual-purpose diagnostic platform designed for workshops working on both 12V passenger vehicles and 24V heavy-duty trucks and commercial vehicles.
Instead of requiring separate car and truck diagnostic tools, the D9HD combines full-system diagnostics, bi-directional testing, ECU coding, topology mapping and 40+ service functions in one powerful workshop package. Its heavy-duty VCI automatically switches between 12V and 24V systems.
