Full-system scan of engine, transmission and ABS on 12V and 24V heavy trucks over J1939 and J1708, plus OBD2 code reading on cars and pickups.
The HD601 is a handheld heavy-duty scanner for owner-operators and fleet shops that need to see past the engine. It covers 12V and 24V trucks from Freightliner, Peterbilt, Kenworth, International, Volvo and Western Star with Cummins, Detroit and PACCAR power, communicating over SAE J1939 and J1587/J1708. Deutsch 6-pin and 9-pin connectors plus a 16-pin OBD2 lead cover older and newer cabs.
Full-system mode reaches the engine, transmission, ABS and other supported modules. Run a quick scan or full scan, read and clear fault codes, and pull live data and freeze-frame data from the moment a fault set. When a transmission controller logs a code, the built-in DTC library decodes it on the spot, and you can type in an SPN and FMI by hand to look up a code read off a dash display - useful on the roadside with no signal.
On cars and light trucks it works as a standard OBD2 code reader (engine only). Software updates are free for life with no subscription.
