5.2.1.2.4 CAN State Manager Detection Notified by CanSm_ControllerBusOff(controller) (seeCAN Interface above) Reaction • Count the bus-off events • Start the error recovery mechanism Report • If the error is confirmed, it is reported to the DEM. If the recovery succeeds, the event is cleared from the DEM (see [SWS_CanSM_00605], [SWS_CanSM_00498], [SWS_CanSM_00522]). The DEM event for this error is configured per CAN network in the CANSM_E_BUS_OFF (see [ECUC_CanSM_00070]). • CANSM informs the Communication Manager about the communication status (COMM_SILENT_COMMUNICATION) notified with ComM_BusSM_ModeIndication (see [SWS_CanSM_00521]) • CANSM informs the BSW State Manager of the BusOff event (with BswM_CanSM_CurrentState) (see [SWS_CanSM_00508]) Recovery [SWS_CanSM_00509] The CAN State Manager controls the error recovery mechanism, which includes • a reset of the CAN controller: CanIf_SetControllerMode(..., CANSM_CS_STARTED) • disabling/enabling the transmit path: CanIf_SetPduMode(...,CANIF_SET_TX_OFFLINE/ CANIF_SET_TX_ONLINE)
