Hello,

This could be an issue with the ABS module.
The 4 Wheel Anti-Lock Brake System Module is located at the left side of the engine compartment.

The electronic brake control module controls the ABS system for this vehicle, and if the on-board diagnostics detect any faults within the ABS system it will trigger the light.

The best course of action would be to see if you can retrieve the ABS codes. As this can help with the diagnostics.

Here is a helpful guide to retrieve the ABS codes:

I have attached diagrams for your reference.

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