The company constantly strives for product quality, technology, design and sustainability and adheres to the spirit of people-oriented and innovative efforts to make great contributions in the field of automotive technology. Built for truck owners, fleets, and repair shops, HD3400 PRO combines vehicle and ECU scanning, OEM-specific fault codes, DPF service functions, topology mapping, graphing live data, and pre/post-scan reports to find issues faster, document findings, and verify repairs. Free Wi‑Fi updates with no annual software fees, built-in diagnostic tools, and pre/post-repair scan records help keep service work clearer and better documented. Run DPF forced regeneration on compatible heavy-duty trucks when required operating conditions are met. Monitor the regeneration process from the scanner to help address soot accumulation, restore exhaust flow, and support aftertreatment service without relying on unnecessary trial-and-error. Function availability varies by vehicle, engine, model year, and system Read engine-specific fault codes, clear supported codes after service, and monitor live data in lists or graphs. Viewing values such as engine speed, coolant temperature, boost pressure, fuel rail pressure, and DPF data helps reveal abnormal patterns, narrow down likely causes, and reduce guesswork before parts are replaced. Available functions and data vary by vehicle and system. Connect to compatible heavy-duty trucks through 6-pin, 9-pin, or 16-pin ports and establish communication with fewer setup steps. Using the appropriate adapter helps owner-operators, fleets, and repair shops move from connection to diagnosis more efficiently, reducing avoidable setup errors and time spent identifying the correct interface. Coverage varies by vehicle, model year, and system Create a pre-scan report to record detected faults before service, then compare it with a post-scan report after repairs. Clear before-and-after documentation helps verify completed work, identify remaining issues, support customer communication, and maintain organized fleet or repair records. Reports can be saved, printed, or shared; supported content varies by vehicle. Download available software updates directly over Wi-Fi without connecting the scanner to a computer. Simple on-device updating helps keep vehicle coverage, functions, and software improvements current while avoiding recurring annual software fees. Update content, release timing, and supported applications may vary by software version. Does it support DPF regeneration on 2017 and newer Freightliner trucks with Detroit engines? For 2017 and newer models, we recommend the dedicated ANCEL HD431 truck scanner. HD3400 PRO generally supports DPF regeneration on pre-2017 Freightliner trucks with Detroit engines. Confirm compatibility before purchase. Does it support DPF regeneration on Isuzu, Hino, and FUSO trucks? Yes, select trucks with Isuzu, Hino, FUSO, or Cummins diesel engines support DPF regeneration and maintenance light reset. GM gasoline and Daimler/Mercedes-Benz-based diesel applications are not supported. Both functions vary by model year and engine Why won't DPF regeneration work even though my engine is listed as supported? Some Volvo trucks with Volvo engines cannot start DPF regen via a scan tool, even when the engine is covered. This is a vehicle limitation. Additionally, unresolved faults or unmet operating conditions required by the vehicle can prevent regen. Does it support DPF regeneration on Chevrolet/GMC Duramax or Ram pickups? DPF regeneration is not supported on these pickups. However, partial code reading and clearing may be available through the Diesel OBD or OBDII menu on compatible vehicles. What if it shows ECU error or won't connect? Please check ignition, cable connection, and vehicle compatibility. For further assistance, use Amazon’s message system to find us
