Umm... no offense but your english makes it difficult to understand your question.
What are you trying to ask?
There is no "second level" to the Sandcrawler mission.
Are you asking what the second Tatooine mission where you travel to the Jawa Sandcrawler is? In that mission you have to get an R5 droid out of the Jawa's Sandcrawler to take to the Academy for info about the Cult. There's no "Sith Council" in this game.
