Hello,

The ABS light gets illuminated when the on-board diagnostic system detects any fault within the ABS system.
It could be one of the wheel speed sensors, bad wiring, or faulty ABS module. Typically worn brake pads or rotors does not trigger that light. So, you could have all the pads and rotors in good condition but have the light due to a sensor.

The best course of action would be to have the vehicle scanned to retrieve the ABS codes. This will help with the diagnostics.

Here is a helpful video:

I have attached diagrams for ABS components below.

Please let me know if you have any questions.
Thank you.
