Designed specifically for diesel engines, this scanner is compatible with a variety of well-known brands, including Cummins, Detroit, Caterpillar, Paccar, Hino, and more. Its versatility and range of features make it an essential addition to any fleet manager’s toolkit. I can confidently say that investing in the HD500 will not only streamline diagnostics but also save you time and money in the long run.

One of the standout features of the HD500 is its advanced DPF management capabilities.

This level of diagnostic precision is invaluable for maintaining engine health and preventing more severe problems from arising, ultimately ensuring that your fleet runs smoothly.

The HD500 also provides speed limit reset and ABS functionality. Being able to check and adjust the engine and vehicle speed limits while stationary is a major safety feature. It ensures that your vehicles operate within safe parameters, which is especially important for commercial drivers. Additionally, the ABS functionality allows you to remove air from the ABS module, ensuring that your braking system functions at its best. These features not only promote safety but can also enhance the overall reliability of your vehicles.

One of the most appealing aspects of the FOXWELL HD500 is its capability to access all major systems effortlessly. This includes diagnostics for the engine, ABS, SRS, EPB, and more. The scanner provides full HD OBD/EOBD/OBD2 service modes, including reading and erasing codes and live data analysis. This comprehensive diagnostic capability allows me to identify issues quickly and apply the necessary solutions without delay, which is vital in a commercial setting where time is money.

Moreover, the HD500 is not limited to just heavy-duty trucks; it also supports various other vehicles, including pickup trucks, buses, trailers, and agricultural machinery.
