The XTOOL HDGURU is a compact heavy-duty vehicle diagnostic tool designed for technicians, mechanics, and small fleet service operations working with Cummins-powered and heavy-duty vehicles. Running on a Linux operating system with a 5.45-inch display, the HDGURU combines essential diagnostic functions with advanced Cummins service capabilities in a portable, wired diagnostic platform.
For Cummins ECU diagnostics, the HDGURU supports DTC scanning and clearing, ECU information, live data, freeze-frame data, and additional diagnostic functions through OBD2 and 6+9-pin Cummins diagnostic connections. It also provides more than 60 bi-directional tests and 35+ Cummins dedicated functions, along with feature activation and parameter modification capabilities across 45+ applications.
The HDGURU also supports generic heavy-duty OBD2 diagnostics, allowing technicians to access functions such as ECU information, diagnostic trouble codes, PID data, and MIL status on supported heavy-duty vehicles. This combination makes the tool useful for routine troubleshooting, system testing, maintenance, and Cummins-focused diagnostic work.
Hardware includes a dual-core Cortex-A7 1.2 GHz processor, 32 GB of storage, a 5.45-inch 1440 × 720 display, and a 3150 mAh 3.6V battery. The unit operates within a 9–36V working-voltage range and uses wired communication with Type-C connectivity.
The package includes the HDGURU tablet, USB Type-C main cable, VGA-to-OBDII-16 main cable, and a Cummins 6+9 adapter, providing the core hardware required for its supported diagnostic connections.
