LAUNCH CR HD V2 is a compact, ARM-based heavy-duty truck scanner that performs full-system diesel diagnostics, reads/clears DTCs, displays live data and supports a wide range of vehicle protocols.

The CR HD V2 is designed for fleet managers, independent technicians and DIYers who need a durable, multi-protocol diagnostic tool for modern and older diesel trucks.
