AUTOSAR DEM
AUTOSAR (AUTomotiveOpen System ARchitecture) is an automotive software architecture for building vehicle applications. It provides system functions, interfaces, drivers and guidelines that enable the separation of software and hardware, and lead to cost-efficiency and reusability. The AUTOSAR architecture provides a diagnostic system, of which DEM (Diagnostic Event Manager) is one of the modules
