Started my car this morning once it warmed up it had a high pitch electrical while, definitely from inside the car. I shut the car off and just put it on accessory and it was still this consistent high pitch whine that won’t go away. My abs, vsc and vsc off lights have been on for a while but this noise just started today. Check the codes and nothing new. Almost sounds like my fuel pump clicks but I’m not sure it drives totally fine and wasn’t sluggish, this whining noise is just super annoying

I think it sounds like the ABS buzzing noise that you are referring to. Common issue a lot of us run into. I think yours is just getting worse. I'd source a used JDM replacement master assembly if that's what it is.

Mine failed too but made a very different noise. I've heard several different noises they can make now when failing. Mine was just a loud buzzing noise (inside the car) along with the lights on the dash. Another sign of a failing abs master unit for those wondering is the the pump motor constantly running and tying to pump up the accumulator. Sounds like the old airbag suspension pumps on Chevys/Fords etc when they are leaky and constantly pumping back up. Worst case I've ever heard of is actual hydraulic failure and pedal to the floor no brakes.
If the OP is experiencing any of these, the abs master cylinder unit is probably the source of the noise too. But I would like to hear a sound clip of the noise if you get a chance Jackson666.
