DPF Regeneration is used to clear PM (Particulate Matter) from the DPF filter through continuous combustion oxidation mode, to stabilize the filter performance. An unmaintained DPF runs your vehicles unnecessarily hard and less efficient, causes power loss, increased fuel consumption, and even engine derate and shutdown. Taking your truck to a repair shop for DPF service will cost you $500-$2000 per time. FOXWELL HD500 provides OEM level DPF function for Cummins, Detroit, Caterpillar, International, Hino, Paccar, helping you complete professional DPF service by yourself, save a lot of maintenance costs and downtime.





Initiate forced active DPF regeneration, raise exhaust temperature to burn off excess soot in the DPF filter, solve severe DPF clogging issues, restore engine power and acceleration performance.
Reset DPF related information, DPR state reset, clear DPF fault codes, turn off DPF warning light, reset DPF life cycle after filter replacement or maintenance.
Support BlueTec system diagnostics, differential pressure check, monitor DPF filter pressure difference, quickly locate DPF filter clogging and pressure sensor faults.
Support DPD forced regeneration, DPD related parameter reset, optimize DPF system operation, ensure the vehicle meets emission standards, avoid failed emission inspection.




The cylinder cut-off test can accurately diagnose engine failure problems. HD500 sends a command to the ECU to cut off the injector of a specific cylinder, and judges the working condition of the cylinder by observing the engine speed fluctuation. The greater the engine speed drops, the better the cylinder works; if the speed drop is not obvious, the cylinder may be faulty. This function helps you quickly locate faulty cylinders without disassembling the engine, provides clear guidance for maintenance, saves a lot of time and maintenance costs.
Limit setting function enables you to check and set the engine speed and vehicle road speed limit when the vehicle is stationary, adjust or cancel the maximum speed limit of your vehicle. It ensures driving safety, helps your vehicle comply with the legal speed limit regulations of different US states, and can also be used for engine protection when certain cylinders are not working properly.
Professional ABS brake bleeding function helps you get a firm brake pedal by removing air from the ABS module after brake system repair. It ensures that the vehicle can respond quickly during emergency braking, prevents the wheels from completely locking, reduces gas resistance in the brake system, prevents foam generation, ensures the normal operation of the ABS system, and improves driving safety.
