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.

If you have a good scanner or a bluetooth dongle and an app like torque you would be able to watch and log the running conditions. You can even add alarms for when solenoids are activated. It's less then $30 in total and worth the investment.

You can also use a multimeter to measure voltage when the part is activated.
