That's the port where the Toyota dealerships can scan for problems in your engine. The regular OBD2 Port is under your steering column. The one Toyota dealerships can use is proprietary and more in depth but it would most likely cost a lot of money just to have them connect their scan tool to tell you what the check engine light means. I wouldn't worry about it being cracked.
I just taped it up better just do nothing gets ruined more than it already has been
