Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. [1] It is derived from ISO 14230-3 and the now obsolete ISO 15765-3 (Diagnostic Communication over Controller Area Network (DoCAN) [2]). 'Unified' in this context ...
The standards define protocols, data models, file formats and application programming interfaces for the use in the development and testing of automotive electronic control units. A large amount of popular tools in the areas of simulation, measurement, calibration and test automation are compliant to ASAM standards.
