The ABS light gets triggered when the on-board diagnostic system detects a fault within the ABS system. It could be a sensor, wiring issue or the module. It can also be due to a loose sensor or connector.
The best course of action is to scan and retrieve the ABS codes, as that can help to figure out the issue.
Here is a helpful video that shows how to retrieve the ABS codes:
The rear wheel speed sensors are mounted at the outboard ends of the axle.
The front wheel speed sensors are mounted to the steering knuckles.
The ABS module is located under the hood.
I have attached diagrams for all those components and replacement procedures below.
Please let me know if you have any questions.
