Issue after changing my brake booster

So I just changed the brake booster on my 2014 CX-9 due to hissing noise, whistle noise when depressed fully and soft braking. Everything is back to normal now except for the tcs/dsc lights stay illuminated about 30 seconds into the car starting. Anyone know why? I’ve tried the steering wheel turn to right then to the left then center and the lights are still on. Abs is functioning normally. I should also mention I swapped out the brake light switch as well. Any advice? Thanks!
 
Did you have to unplug any sensors? I'm thinking along the lines of low brake fluid level sensor.

Speaking of, how is the brake fluid level?
