ABS coming on - me and my grand prix

2002 Grand Prix 69K, the ABS starting working on its own, track on button lite up, I can feel it the brakes shuttering, has happened about 4 times on its own, perfectly dry roads, not speeding…any advise

Any ABS or Check Engine lights on? Wheel speed sensors acting up maybe. Take them off and clean the connections, make sure they’re on tight.

thanks
