Fast answers. Real commands. No laptop required.
The Diesel Handheld Pro is built for diesel techs who need to diagnose, reset, and regenerate trucks without dragging out a laptop or waiting on dealer software. It keeps work moving by putting serious heavy-duty diagnostic power into a rugged handheld that’s always ready when a truck rolls in or breaks down in the yard.
Built by Diesel Laptops for real-world shop conditions, the Diesel Handheld Pro reads and clears faults, displays live data, runs DPF regenerations on most makes, performs emissions and maintenance resets, and connects directly into Diesel Repair when deeper answers are needed. Portable, fast, and dependable, it earns its place in any shop or service truck.
Designed for how technicians actually work
This tool is intentionally simple so it never slows you down. Plug it in, choose HD or EOBD, run an automatic scan, and select the modules found on the vehicle. From there, reading faults, clearing codes, viewing freeze frame data, checking live parameters, or running a DPF regeneration is quick and straightforward.
Regenerations are accessed directly from the main menu so there’s no digging and no guesswork.
