The ABS sensor light is on when I start the car, the traction light comes on almost right away as well (picture of outline of car with lines under it, next to ABS). I put the SUV into reverse and try to back up and it acts like the brakes are grabbing on the rear wheels.

Why is my abs light on and Trac off?

Here’s why: Older ABS braking systems used a steel toothed ring and a magnetized wheel speed sensor. As rust accumulated on the tone ring it would throw debris onto the magnetic sensor and that debris would interfere with the signal, causing the ABS to activate prematurely. GM changed the wheel speed sensor and tone rings in these vehicles.

How does the ABS system keep the car under control?

The system can then use the brakes to keep the vehicle under control during slippery situations. The ABS system uses sensors at each wheel to monitor their rotational speed. A computer monitors the signals from all four wheels and the position of the brake pedal to ensure the vehicle is stable and under control.
