Figure 7.14: Example for using Dem_SetEventStatus [SWS_Dem_00331] Upstream requirements: RS_Diag_04179 ⌈The Dem module shall provide the capability to reset the failed status of an event without reporting a passed result (refer to Dem_ResetEventStatus).⌋ Note: Dem_ResetEventStatus does not mean an event status report (like done by Dem_SetEventStatus). After the call, the monitor status is not qualified or tested. Monitors will use the function Dem_ResetEventStatus in order to deactivate limp home and switch back to normal operation. At this point in time, the monitor has typically not been OK-tested and therefore Dem_SetEventStatus with tested and passed cannot be used. [SWS_Dem_00187] Behavior of Dem_ResetEventStatus Upstream requirements: RS_Diag_04067 ⌈The function Dem_ResetEventStatus shall set the event status bit 0 (T est- Failed) to 0 and reset the Dem-internal debounce algorithm to initial values if configured. The Dem shall execute this action asynchronously at a later point in time. ⌋ A later point in time means that the exact moment is implementation specific. This could be the next main function and after Dem_ResetEventStatus has returned. Also a possible call of the status change callback is triggered asynchronously . Note: The function Dem_ResetEventStatus does not change the monitor status and UDS status bit 6 and does not clear the pre-stored freeze frame. [SWS_Dem_00638] Upstream requirements: RS_Diag_04067 ⌈The function Dem_ResetEventStatus shall return E_NOT_OK, if the event was already tested this operation cycle ( UDS status bit 6 is set to 0). ⌋
