This is a brake warning light for the SBC system if the brakes are working just fine then
Most likely just a bad brake light switch .
This brake switch also activates the shift solenoid to release the shifter so you can select R and P .
First check the fuses.
Best to be safe is to get hooked up to a diagnostic scan tool and check for SBC codes .
Brake switch is located on the top half of the foot brake pedal .
