Techstream -ECU Connect ???
The program connects to my car but it shows that it is not connecting to the yellow ECU and the blue light ECU, I don't know what it means but I wanted to ask if it's the same with you:
The car does not display any errors and drives normally.
Yellow= ECU status unknown
Light Blue w/Asterisk=ECU communication OK in past times but not responding now

I am not exactly sure I understand the issue you are referring to..
The section above the Main Cells (marked in Red Square in the picture below) is just an explanation for the different colors you can encounter on said Main Cells, and the definition of what those colors mean. The picture below shows a few instances of what an actual issue would look like, along with the explanation for each.
In your case, aside from Pre-Crash and Sliding Roof not responding, as evident by the Asterisk by their Names in each respective Cell (likely due to lack of thereof), all the other ECUs, at least from the ones visible in the screenshot you posted, are functioning normally.
Hope this helps and best of luck!
