Need to start the New Romulus story mission Mountain Pass to be able to access the area (Mountain Pass) and access the Shuttle Codes mission objectives there.
Can you post a screenshot of your New Romulus story arc please? (Missions - Story Missions - New Romulus)
Story Arc = Episode (s)
New Romulus story arc has the episode "Mountain Base". Even if completed, in order to be able to finish "Secret Shuttle Codes" you have to do "Mountain Base" again/rerun (as Shuttle Codes objectives are only available in the Mountain Base area that is only accessible by replaying "Mountain Base" mission).
This is a PS4 sub forum, btw. But it should work the same way on PC.

My bad, the Mission name is actually "Mountain Base"
