Detroit Diesel

Ally Diagnostics stocks Detroit Diesel diagnostic tools for UK truck and commercial vehicle workshops working on Detroit-powered trucks and engines.
DDEC engine and aftertreatment diagnostics
Detroit Diesel’s DDEC engine management and aftertreatment systems need a proper interface to read fault codes, view live data and carry out the resets a basic scanner cannot reach. Our Detroit Diesel kits connect to the engine, transmission and emissions systems on Detroit-powered trucks and are supplied ready to use.
Built for fleet and independent truck workshops
Whether you run one bay or a full fleet workshop, these kits are set up the same way – tested before dispatch, with the software licensed and ready to install.
Buying and support
Every kit includes remote installation and activation over TeamViewer from our own technicians. Get in touch if you are not sure which interface matches your workshop.
