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.

What happens when the ABS system is not working?

The sensors detect wheel speed, and will send a message to the ABS module to rapidly pump the brakes when it is detected that the vehicle is skidding or has lost traction. When the ABS system is not functioning then loss of traction, skidding, and hydroplaning are far more likely to occur under heavy braking conditions.

When did GM replace the traction control ABS?
