Nissan197

For a couple of months my service brake light and stabilitrak warning came on. When the issue started I would turn the car off and the system would reset itself and it would be good for some time. Now the warning lights are always on and the beeping alarm goes off every few minutes. There is no loss of power and everything else appears to be working fine, except for the cruise control. No codes when I checked with a code reader. I thought it was the brake pedal switch/sensor, but I just replaced that part and it did not fix the issue. Any ideas? Thanks.
