Truck & bus diagnostics

Heavy-duty diagnostics for trucks, buses, vans and construction machinery. The Launch CRP129 HD reads all systems across 61 commercial brands — engine, ABS, transmission and body electronics — on both 24V commercial and 12V light commercial vehicles.

European truck coverage

The full European range is included: MAN, DAF, Scania, Iveco, Mercedes-Benz, Renault, Volvo, Neoplan, Setra and more, alongside the American and Japanese makes.

On a MAN TGX, for example, the tool reaches the Exhaust Gas Aftertreatment (AdBlue) module for fault codes, live data and actuation tests — metering module, supply pump and AdBlue circuit bleeding — not just code reading.

Check before you order

Truck diagnostics is not a car scanner with a different plug. Commercial vehicles run 24V systems and manufacturer-specific protocols, and the adapter set matters as much as the software. If you run a mixed fleet, tell us what you operate and we will confirm coverage for your makes before you buy.
