2019 model brake fluid low warning at startup

[keanezheng]

During this past winter, I have seen brake fluid level warning at start ups especially the morning. I checked the fluid level, and it seems normal.
The warning stays on for a few seconds, as soon as I start driving, it goes away.

Anybody has the same issue? I flushed the fluid about around 30K miles and now the car has 45K.
Is it a bad sensor? It seems easy to replace
Also I do have a ABS DTC C2206-00 and I could not erase with my TOPDON carpal OBD scanner.

Is it a sensor issue or an ABS issue? I couldnt feel anything mechanically when I brake.

IIRC, I had to use SGW bypass cable to clear ABS DTC`s.
The C2206 could be caused by the ABS module?
