A fully equipped vehicle produces several gigabits of data per second. In particular, this data provides information about the technical condition of the vehicle. In raw format and also in standardized data description formats, however, this data is generally not comprehensible to humans. Therefore, they are interpreted by software and converted into human-readable information. Softing's Smart Diagnostic Engine (SDA) is a platform-independent runtime system that interprets and executes diagnostic functions, simple diagnostic services and even complex and automated diagnostic sequences for precisely this purpose.
