It supports 6- and 9-pin HDOBD and OBD2 connectors and covers popular heavy truck OEMs including Cummins, PACCAR, Caterpillar, Detroit, Volvo, Mack and International. The unit combines core scan functions with targeted aftertreatment controls, pre\/post-scan reporting, and in-device wiring references so technicians and owner-operators can diagnose, document, and repair trucks with fewer trips to the shop.\n\n\u003ch3\u003eWhich trucks and engines does the HD3400 Pro work with?\u003c\/h3\u003e\n\u003cp\u003eThe scanner targets heavy-duty diesel platforms and many medium-duty models. It supports Diesel OBD and OBD2 protocols across Freightliner, Peterbilt, Kenworth, HD Volvo, Mack, International, Western Star, and others. Certain truck models or newer UDS-based Detroit ECUs may limit DPF regen functions—always confirm engine family before relying on a specific procedure.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with Cummins, PACCAR, Caterpillar, Detroit, Volvo, Mack, International\u003c\/li\u003e\n  \u003cli\u003eWorks on 6-pin\/9-pin HDOBD and standard OBD2 connectors where supported\u003c\/li\u003e\n  \u003cli\u003ePerforms oil reset and basic functions on supported Isuzu, Fuso, and Hino units\u003c\/li\u003e\n  \u003cli\u003eNot intended for light-duty Duramax or Ram diesel pickups\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the HD3400 Pro help with DPF regeneration and aftertreatment service?\u003c\/h3\u003e\n\u003cp\u003eThis tool offers forced DPF regeneration and reset procedures on many supported diesel engines, helping address soot buildup and aftertreatment flags without waiting for dealer service. Built-in CAN3 channel access means some regen tasks can be executed without buying a separate CAN-3 adapter.
