Overview
A small fleet shop or an owner-operator's cab is where this Launch scanner fits. It reads and clears codes across core truck systems, forces DPF regeneration and runs service resets, with remote technician support built in.
Forced regen and resets save trips to the dealer for diesel owners. Functions vary by make and model, and updates are free for a set period only.
Who it's for
Truck owners dealing with DPF warnings will get the most from it. Car-only drivers will pay for heavy-duty features they never use.
Pros and cons
- Forced DPF regeneration
- Wide heavy-duty protocol support
- Many service resets
- Live data and freeze frame
- Coverage varies by truck
- Short hardware warranty
- Updates free for a set period
Performance notes
The scanner talks over the truck's own protocols, so coverage depends on the make and year. Forced regen burns off soot when the truck cannot clean the filter on its own while driving.
