Diesel trucks have systems gas scanners often ignore, like the DPF, DEF, EGR, and turbo controls. The right scanner reads that data and can even run regenerations. Here are the best scanners for Powerstroke, Cummins, and Duramax diesel owners.

What diesel owners need
Modern diesels have complex emissions systems: diesel particulate filter (DPF), diesel exhaust fluid (DEF/SCR), and EGR. A good diesel scanner reads these codes and their live data, not just generic engine faults.
The best tools can also command a forced DPF regeneration and reset service intervals, which are common diesel maintenance needs.
DPF, DEF/SCR, and EGR data and codes
Forced DPF regeneration on supported trucks
Turbo, fuel-rail, and glow-plug live data
Make sure it covers your engine
Coverage differs across Ford Powerstroke, Ram Cummins, and GM Duramax. Confirm the scanner explicitly lists your engine and the diesel functions you need.
Some tools cover light-duty diesel pickups well but not heavy-duty commercial trucks, so match the tool to your vehicle.
Best picks for diesel pickups
The Autel MK808 (with diesel coverage) and Foxwell NT634 read diesel-specific systems and perform many resets. Ancel's diesel-focused tools like the X7 HD also target trucks.
For Ford Powerstroke owners specifically, FORScan on a laptop with a compatible adapter is powerful and inexpensive.
Heavy-duty vs light-duty
For light-duty diesel pickups, the tools above work well. For heavy-duty and commercial diesel (with 9-pin connectors and J1939), you need a dedicated heavy-duty scanner.
Check the connector type and protocol support before buying for a big rig.

❓ FAQ
What is the best OBD2 scanner for a diesel truck?
For diesel pickups, the Autel MK808 with diesel coverage is a great all-in-one. Ford Powerstroke owners get exceptional value from FORScan plus a Vgate vLinker FS adapter.
Can these do a forced DPF regeneration?
Some can on supported trucks. FORScan (Ford), the Autel MaxiSys, and certain Ancel diesel tools support forced regen. Confirm your specific engine is covered before relying on it.
Will a regular scanner read DEF and DPF data?
Basic scanners usually show only generic engine codes. To read DEF/SCR and DPF live data and codes, you need a diesel-capable tool that lists those systems for your truck.
Does one tool cover Powerstroke, Cummins, and Duramax?
Broad tools like the Autel MK808 and Foxwell NT634 cover all three at different depths. For the deepest single-engine coverage, a make-specific approach like FORScan for Ford can be better.
Can I use these on a heavy-duty commercial diesel?
Most light-duty tools do not cover heavy-duty trucks with 9-pin J1939 connectors. For commercial diesels, buy a dedicated heavy-duty scanner that supports those protocols.
Is FORScan good for diesel?
For Ford Powerstroke, yes. FORScan offers deep diagnostics, forced regen, and service functions at very low cost when paired with a compatible MS-CAN adapter.
