Detroit Diesel Diagnostic Link (DDDL) is a Windows-based diagnostic and programming software suite for Detroit Diesel engines and Freightliner/Western Star vehicles. The Pro Edition provides all dealer-level diagnostic functions, including reading and clearing fault codes, running service routines, performing DPF regens, turbo tests, and advanced system tests. It enables users to change ECU parameters, reprogram engine controllers, and update ECMs on 2010 and newer Freightliner trucks, as well as parameter changes on Cascadia 2017 and newer models. The software includes three integrated programs: DDDL v8.xx for 2007 and newer engines, DDDL v6.xx for 2006 and older engines, and DDEC Reports for trip and lifetime reporting. The Pro Edition is intended for professional technicians and fleet maintenance operations requiring full access to Detroit Diesel engine diagnostics and programming capabilities. The license is valid for 12 months and is compatible with RP1210-compliant adapters.
