Reads and clears fault codes on Cummins and Caterpillar heavy trucks across engine, transmission, ABS and fuel systems, with forced D.P.F regeneration built in.
The HD430 is a handheld heavy-duty scan tool built for Cummins and Caterpillar diesel trucks that need more than a basic code reader. Past soot buildup, extended idling and stop-and-go routes clog the diesel particulate filter and throw a derate or check-engine light - this tool lets you read the DPF-related codes, check live data, and run a parked or forced D.P.F regeneration on compatible engines to burn off accumulated soot instead of towing the truck to a dealer for the same procedure.
Beyond DPF work it covers full-system diagnostics on supported engine, transmission, ABS and fuel modules: read and clear standard and manufacturer-specific fault codes, pull live and freeze-frame data, and use the built-in DTC lookup to understand what a code actually means before you start swapping parts. It supports 12V/24V commercial platforms with Cummins, Caterpillar, Detroit and PACCAR engines over SAE J1939, J1708, J1850 PWM/VPW and the common ISO protocols, and ships with CAT-9, diesel 6-pin/9-pin and OBD2 16-pin connectors to cover older and newer trucks on one tool.
It runs on a 4.3-inch built-in display with physical buttons - no phone, tablet or Bluetooth pairing required - and updates over Wi-Fi for free for life, so there's no annual subscription to keep the DPF and fault-code library current. Comes in a protective storage case.
