FOXWELL HD500 Heavy Duty Diesel Truck Scanner — Black, Full-System Diagnostics & DPF Regen

FOXWELL HD500 is a professional-grade heavy-duty diesel scanner that performs full-system diagnostics, DPF regeneration, injector cutoff testing and speed-limit adjustments for trucks, buses and equipment.

The HD500 combines workshop-grade functions with a user-friendly interface so fleet managers, technicians and owner-operators can diagnose faults faster and carry out common service actions without multiple tools. It supports major heavy-duty protocols and comes with a set of adapters and lifetime software updates to cover many popular diesel platforms.

How does the HD500 diagnose heavy-duty vehicles?

The unit reads and clears diagnostic trouble codes across supported ECUs and displays ECU information and live sensor data for troubleshooting. Its compatibility with J1939, J1708/J1587 and OBD/EOBD means it handles many diesel protocols and systems.

• Read/clear codes for Engine, ABS, SRS, parking brake and aftertreatment
• View ECU ID, software version and fault freeze-frame data
• Monitor live parameters: RPM, coolant temp, fuel pressure, boost, DPF pressure

Can the HD500 help with DPF-related problems?

Yes — when supported by the vehicle it can initiate DPF regeneration to help clear soot and restore exhaust flow, and it displays relevant aftertreatment data and status. This makes it easier to decide if a regen or further service is needed.

• Manual DPF regen function on compatible vehicles
• Shows DPF soot/load readings and related sensor values
• Includes status and reset features where supported (check vehicle compatibility)

What diagnostic service functions does the HD500 perform?

Beyond code reading, the HD500 offers a range of service routines used commonly in workshop and fleet environments, helping isolate faults and complete maintenance tasks. Functions vary by make, model and ECU, so verify support for specific vehicles before relying on any single procedure.

• Injector cutoff testing to help pinpoint weak cylinders
• ABS bleeding, parking brake relearn and system resets where supported
• View and adjust supported vehicle and engine speed limit parameters

Which makes and vehicles will the HD500 cover?

The HD500 is designed for widespread heavy-duty use: it includes multiple adapters and supports common diesel brands and modules found in trucks, buses, tractors and construction equipment. Coverage depends on year, ECU and protocol; the kit includes lifetime updates to expand compatibility over time.

• Works with Cummins, Detroit, Caterpillar, PACCAR and many other diesel platforms
• Supplied adapters: 6-pin, 9-pin, CAT 9-pin, CAT 14-pin and 16-pin OBD
• Includes lifetime free software updates—no annual subscription required

Who is this for? FOXWELL HD500 is aimed at diesel technicians, independent repair shops, fleet maintenance teams and serious owner-operators who need a single, portable scanner capable of multi-system diagnostics and common service functions. If you regularly work on heavy-duty trucks, buses, agricultural machines or construction equipment and want practical tools for fault finding, DPF service actions, injector tests and speed-limit parameter checks, the HD500 is built to streamline those tasks. Always confirm vehicle and function compatibility before purchase, as supported features vary by make, model, engine and ECU.
