Dem

Diagnostic Event Manager: The Dem module implements a fault memory. The standardized interface enables uniform development of manufacturer independent SWCs to report faults, enable conditons states or re-starting operation cycles. The Dem module is responsible for administering the DiagnosticTroubleCode states, environmental data, and for storing the data in NVRAM.

The legal requirements of OBDII (SAE1979) OBDonUDS (SAE J1979-2) and WWH-OBD (ISO27145) are also supported.
