Designed for heavy-duty truck owner-operators and small commercial fleets, the Diesel Decoder is a powerful one-of-a-kind diagnostic tool for all heavy-duty truck makes.
Just plug it into a diagnostic port, sync it via Bluetooth® to the free Diesel Decoder by Diesel Laptops app, and use your smartphone to view fault codes and get repair information. No expensive code-scanning hardware and software needed!
Knowing what’s wrong with a vehicle can make all the difference– if there’s a way to put that knowledge to work. Diesel Decoder Pro leverages diagnostic data with bi-directional functions such as DPF regenerations and aftertreatment reset commands. Diesel Decoder users can upgrade to the Pro plan for just $29.99/month - purchased through Google Play or the Apple App Store - and get their vehicles back on the road without an expensive tow or dealer diagnostic visit.
View a full list of current Bi-Directional commands, including DPF regens, below. Our team is constantly working to improve & expand functionality.
