ANCEL HD431 Heavy-Duty Truck Scanner — DPF Regen & Full-System Diagnostics for Detroit & Paccar, Rugged Handheld with Wi‑Fi Update

ANCEL HD431 is a standalone heavy-duty truck diagnostic scanner that performs full-system diagnostics and forced DPF regeneration on Detroit and Paccar engines without needing a phone.

The ANCEL HD431 combines shop-grade capabilities in a rugged handheld unit designed for fleet technicians, owner-operators, and roadside professionals. It reads and clears fault codes from OBD2 and HDOBD systems, performs forced diesel particulate filter (DPF) regeneration on supported Detroit and Paccar powerplants, and stores diagnostic reports locally. Built for real-world use, the HD431 supports multiple heavy-truck protocols, offers lifelong Wi‑Fi updates, and puts physical controls and a glare-resistant screen where you can access them quickly—no Bluetooth, no app, no subscription.

How does the HD431 handle DPF regeneration on Detroit and Paccar engines?

The HD431 gives you a dedicated interface for initiating forced DPF regeneration on many Detroit and Paccar engines, including PX and DD/MX families. The procedure can be started from the driver’s seat when the truck is safe and ready, reducing downtime and avoiding expensive tow-and-shop situations.

• Supports PX-7, PX-9, MX-11, MX-13; Detroit DD13/15/16 coverage
• Dedicated regeneration button and guided prompts for safe execution
• Saves hours compared with waiting for a service call or shop appointment

Which vehicles and protocols does this scanner support?

HD431 connects to diesel 6-pin, 9-pin, and standard OBDII 16-pin ports and covers common heavy-duty protocols such as SAE J1939 and J1708, plus multiple ISO standards and newer UDS implementations. That makes it compatible with Freightliner, Western Star, Kenworth, Peterbilt and many other OEMs using Detroit or Paccar powertrains.

• Includes adapters for 6-pin, 9-pin, and 16-pin connections

What kind of diagnostics and daily workflow features are included?
