Elantra RD Purge solenoid and CCV specific conditions, looking for pre-conditions

When - under WHAT SPECIFIC CONDITIONS - does the Elantra RD open the purge solenoid for vapor release? I'm looking for the condition-satisfying sensor and actuator states ... during ON/Running.

When - under WHAT SPECIFIC CONDITIONS - does the Elantra RD close the CCV? I'm looking for the condition-satisfying sensor and actuator states ... during ON/Running ... and during or just after Start.

Finally, IF the CCV was closed (energized) (leak testing underway, e.g.,) at the time the car was turned off ... AND the ignition switch was then immediately turned back to ON (but not running) BEFORE the Main ECU Relay turned off ... would the CCV remain closed or not (would the ECU attempt to allow the test to run to completion) (would the ECU keep the CCV energized)?

Thanks.
