FOXWELL HD500 Heavy-Duty Diesel Scanner — DPF Regen, Injector Cutoff, Multi-Adapter Kit

The FOXWELL HD500 is engineered for technicians and fleet managers who need accurate, vehicle-specific diesel diagnostics without complex PC setups. Supplied with multiple adapters (6-pin, 9-pin, CAT-9, CAT-14 and 16-pin), the HD500 connects to an extensive range of heavy equipment, trucks, buses and pickups to access full-system fault codes, live data and essential service operations. It is a handheld solution intended to reduce downtime, isolate injector or DPF issues, and provide actionable information for repair decisions.

How does the HD500 identify engine and system problems quickly?

The HD500 supports major heavy-duty protocols (J1939, J1708, J1587, ISO and CAN variants) and reads manufacturer-specific codes so you get targeted results rather than generic OBD-II suggestions. It pulls live data streams, stores freeze-frame information and lets you clear confirmed faults after repairs.

• Reads and erases engine, ABS, SRS and DPF codes
• Displays live sensor data and freeze-frame captures
• Supports factory custom protocol selection for better accuracy
• Includes multiple adapters for wide connector compatibility

Can it handle DPF regeneration and soot-related diagnostics?

The HD500 includes DPF regen, reset and status control functions to manage particulate filter issues without immediately replacing hardware. Use the tool to initiate controlled regens and verify filter status so technicians can choose the correct next steps.

• Initiate manual DPF regen and reset DPF parameters (not for Isuzu)
• Monitor soot load and regeneration progress in real time
• Helps avoid unnecessary DPF replacement costs

What injector and cylinder troubleshooting features are available?

Pinpointing a failing injector is faster with the HD500’s cylinder cut-off test, which systematically disables individual injectors so you can identify the problematic cylinder. This focused approach reduces guesswork and speeds up part replacement or repair.

• Cylinder cut-off to isolate misfiring or low-power cylinders
• Live engine data to compare injector performance across cylinders
• Guides efficient repairs to reduce diagnostic time

Does the HD500 support vehicle safety and speed functions?

The scanner includes safety-related operations like speed limit setting (on supported engines) and ABS bleeds to restore pedal feel after repairs. Availability varies by make and VIN, so confirm compatibility before performing certain service tasks.

• Speed limit reset and engine/road speed parameter adjustments (check VIN)
• ABS module bleed procedures to restore brake performance
• Coverage across brake, park brake controller and EPB systems

Who this is for: The FOXWELL HD500 is built for diesel technicians, independent repair shops, fleet maintenance teams and owner-operators needing a rugged handheld scanner with deep heavy-duty coverage. It is ideal if you work on Cummins, Caterpillar, Detroit, Paccar and similar diesel platforms and want an all-in-one tool that performs full-system scans, DPF management, injector diagnostics and safety system services. Note: the HD500 does not provide bidirectional control for every manufacturer, does not support VGT calibration, and Allison transmission functions are under development—confirm function availability for your vehicles before purchase. Lifetime free updates and FOXWELL technical support keep the tool current as truck protocols evolve.
