Probably wheel speed sensor failure (in the wheel bearing assembly).
Hi i have an 2001 Chevy impala and my service traction Light is on. plus my safety brake is locked
Have the two front wiring harnesses to the hub bearings replaced. This fixed the problem on my 2001 impala ls.
the traction light comes on telling you there is a low traction condition, not that the system needs service. the anti-lock brake system is the noise you hear. it is a series of hydraulic pumps that is cycling the brake pressure on the locking wheel. that is also what you feel on the pedal. the system is working as it should.
check your wheel speed sensors. One of the wires may be disconnected or broken.
I have a 2000 venture and the traction control light came on. Where do I look first, hubs. Wiring.

My 2002 Impala was doing the same thing. I took it in and they said it was code C1225. Traced to broken LF ABS Speed Sensor Harness. They replaced the harness and charged $231.88 at a dealership.
