anti lock brake system light on?

Hello,

The ABS light gets illuminated when the diagnostic system of the vehicle detects issue(s) within the ABS system.
It could be a sensor that goes on the wheel or a faulty wiring or the ABS module.
Best course of action is to have the vehicle scanned for ABS codes. This can help with the diagnostics and point to what issue you might have.

Here is a helpful video of how to check for ABS codes:

Please let me know of any questions.
Thank you.
