2002 continuous buzzing noise ABS

I am looking for some posts on a continuious buzzing noise that just started
on my wifes suburban and won't turn off with the key. The noise is coming from the ABS pump under the driver seat area of the car. Her ABS light just came on also. Is there a switch that I can find and replace?

Thanks
Tim

If ABS light is on.
You need to get the ABS code and see what is going on.
You will need a ABS brake capable scanner to check it out.
Post back code no.
