A couple times this year while driving all my dash lights including abs go bezerk and the loud warning beep goes crazy. This is accompanied with a strange whining or pumping sound. Usually goes away in a couple minutes or with a shut down or restart. Sound like its coming from master cylinder. Still happens once in a while without the lights and beeping but the noise usually upon startup and goes away in a minute or Considered draining all fluid and taking off pads and cleaning brakes as a start. Problem is its intermittent and can't get it to shop while it's happening. I have video but can't figure out how to post. Any help is appreciated.

I going to start by saying that I'm not very familiar with ABS systems but the sound you are hearing may be the ABS pump. I would do a fluid flush with new fluid and go from there.
