The ABS braking system uses the wheel speed sensors to prevent the wheels from skidding on a hard stop
The Traction control uses the wheel speed sensors to prevent the wheels from spinning on a hard launch
Most commom for either of both of these messages is a fouled wheel speed sensor pigtail or a broken wire or an unplugged one---A data logger or good scanner should tell you which sensor is causing the problem left or right front or rear But I would check all 4 of them Located at each wheel behind the brake rotor with a 2 wire pigtail near by---
Check for mud or sticks got in the star wheel as well---
Driving too FAST on a bumpy road or over railroad tracks will dislodge the connection of the pigtails----
An intermittent warning can be cleared with a scanner or data logger or Tech 2---
I would clear the messages 1st as they may be just a one time thing but if it comes back---then check the pigtail wiring and starwheels
