It’s 2 AM, and there are still 300 miles to the destination when a disturbing yellow warning light suddenly illuminates the dashboard. For long-haul truckers, this moment is always agonizing—uncertain if it’s a minor glitch or a major breakdown, with repair shops dozens of miles away. You’re left with nothing but guesswork.
After facing such situations repeatedly, the need for timely and accurate manual diagnosis becomes crucial. This is why more and more drivers are choosing to keep the Foxwell HD500 — a professional diagnostic tool designed specifically for heavy-duty trucks — in their cabs.
Why Choose the Foxwell HD500?
We’ve noticed a growing demand among heavy-duty diesel truck repair professionals for a diagnostic tool that’s stable, user-friendly, and widely compatible. The HD500 was engineered to address these exact pain points.
Unmatched Protocol Support: It works with 99% of mainstream diesel OBD/OBD2/EOBD protocols for heavy-duty trucks, covering brands like Freightliner, Kenworth, Volvo, International, Mack, Ford, and Peterbilt. Whether it’s legacy protocols (J1587, J1939, J1708) or modern standards (CAN FD, DOIP, ISO27145), the HD500 connects quickly and reads data reliably.
User Feedback-Driven: Drivers often complain that older tools fail to connect to new models or lack critical features. The HD500 doesn’t just read/clear fault codes — it monitors real-time data from the powertrain, emission system, braking system, and electronic control modules, helping you catch issues early and avoid catastrophic failures.
Plug-and-Play Simplicity: You don’t need to be a tech expert. Plug it in, select your vehicle model, and start diagnosing — perfect for roadside emergencies or fleet maintenance.
In short, the HD500 balances professional-grade performance with everyday usability, making it ideal for solo truckers, fleet technicians, and small repair shops alike.
Key Features
1. Forced DPF Regeneration
Applicable to: Models with DPF (post-2007).
DPF systems — standard in modern heavy-duty trucks — are a persistent headache. Many drivers only realize there’s a problem when the vehicle enters limp mode. The HD500 lets you initiate regeneration on-demand, monitoring soot burnout in real time to prevent clogs and reduce costly repair shop visits.
2. Injector Cut-Off Test
Applicable to: Idle roughness, power issues without fault codes.
By disabling injectors one by one and analyzing engine speed fluctuations, the HD500 pinpoints faulty cylinders in under 20 minutes — no more blind disassembly or guesswork.
3. Speed Limit Adjustment
Applicable to: Cross-state transport, regulatory differences.
Easily view and adjust speed limits with one click, ensuring compliance with local laws (e.g., 25 mph in residential areas vs. 75 mph on highways). Avoid fines or power restrictions from incorrect settings.
4. Full-System Diagnosis
Applicable to: Multi-module fault troubleshooting.
The HD500 diagnoses critical systems (engine, transmission, ABS, airbags, EPB) and offers real-time graphical comparison for up to 4 data streams, making it easy to spot abnormal sensor trends.
5. One-Click VIN Recognition
Applicable to: Fleets with frequent vehicle changes.
Automatically reads the VIN and vehicle info upon connection — no more manual model entry.
6. I/M Readiness Status
Applicable to: Emission testing and annual inspections.
Quickly check if your vehicle meets emission regulations. It also works with some light-duty diesel/gasoline vehicles (OBD2-compliant), making the HD500 versatile for both heavy and light trucks.
7. PIN Detection
Applicable to: OBD port contact issues, short circuits.
Measures voltage on the 16-pin OBD port to identify physical connection problems (e.g., oxidized ports, shorted wires). Avoid replacing expensive control modules for simple hardware issues.
