SNIP_CLASSIC_COMM_SECTION_9_3_Network_shutdown_CAN

9.3 Network shutdown (CAN) Figure 9.3 shows the possibilities to shutdown the CAN network. It can be either initiated if the last user releases his COMM_FULL_COMMUNICATION request or ComM_ LimitChannelToNoComMode (see [SWS_ComM_00163]) is called. The behaviour is equal for LIN, FlexRay and Ethernet just with different API names. «module» EcuM «module» Dcm «module» ComM «module» Rte VehicleModeManager «module» Nm «module» CanSM «module» BswM alt Shutdown initiation [No user requests COMM_FULL_COMMUNICATION and no DCM ActiveDiagnostics] [Forcing to COMM_NO_COMMUNICATION state]
