Stabilitrack and traction control

[richyr]

What could be causing my 07 Tahoe to keep showing that the stabilitrack and traction control needs service and then when I go to drive it says the traction control is off. What is the fix for this? Do I just change brakes? Because they need changing or is there something else wrong I just got it out of shop and cleared codes from getting new lifters on cylinder #4. Truck rides and drives great just the service and stabilitrack and traction control came on

Since it was just serviced look under it for any loose wires going to the wheel speed sensor.
