FOXWELL HD500 heavy duty truck scanner 🚚
Product description
This heavy duty diesel truck scanner is built for diagnosing and maintaining commercial diesel engines and related systems, offering DPF management, injector cutoff testing and speed limit adjustments for workshop and roadside use. It helps technicians access engine, ABS, SRS and DPF functions quickly while showing live data and trouble codes, which can streamline troubleshooting on larger vehicles.
Key Points

The FOXWELL HD500 focuses on diesel-specific service functions such as DPF regeneration and injector cylinder cut tests, making it practical for fleets and independent shops. It connects to a wide range of manufacturers including Cummins, Caterpillar, Detroit and Paccar, and includes multiple adapters for 6- and 9-pin diesel sockets and standard 16-pin connections. ⚙️


This tool also offers limit setting for speed and an ABS air-bleed function, both intended to reduce downtime and help maintain vehicle safety systems. For clarity, the HD500 does not support bidirectional control according to the manufacturer, and the speed limit adjustment is not compatible with every engine variant. 🔧

Usage Recommendations
Use the HD500 to read and clear codes, monitor live engine parameters and perform service routines when the vehicle is stationary. If you encounter a manufacturer-custom protocol code, select the correct engine type from the diagnostic menu for more accurate test data. For injector testing, observing RPM changes during a cylinder cutoff can indicate injector condition, and tactile checks on high-pressure lines help corroborate results. 🛠️

Consider that some transmissions and vehicle systems such as Allison transmissions are not currently supported and are listed as under development. For complex bidirectional requirements or proprietary factory functions, this scanner may not provide full control.
