My brake pedal pulses and ABS light is on

Hello,

When the onboard diagnostics of the vehicle detects an issue within the ABS system the light gets triggered. It can be due to a number of reasons.
It can be one of the wheel speed sensors (ABS sensor), faulty module or even a wiring issue.

The best course of action would be to first have the vehicle scanned for ABS trouble codes. This can help with the diagnostic process.

Here is a helpful video:

Also take a look at this guide, it covers the typical ABS issues:

I have attached the ABS inspection guide below.

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