2018 Subaru Brz Abs module constantly buzzing
 

Hi, there was some short circuit in left side 3pin turn signal wiring and some blown fuses, after this when I put abs pump green, squared 40a fuse, abs is buzzing all the time , even if car is turned off. I noticed that this 40a fuse was blown after short circuit happened, but car is front damaged, so maybe this fuse was blown before and thats why it was not buzzing before.
Any idea what to check? I want to avoid changing abs module if possible

If you are blowing fuses you have a short somewhere. I'd start by giving the harness a quick inspection and looking for a cut or pinch. Just because the insulation is not cut doesn't mean the wires inside are not damaged. If nothing looks damaged then you may need to pull the connector and see if you have a short to ground on one of the pins. Refer to the schematic to see what the pin goes to and trace back from there.

No there is no shirt circuit or fuse blowing, it happened because wires touched to each other, Now there is just abs buzzing when I put fuse back, I removed fuse now because of this, not because of blowing

Sounds like that short killed the module. There may be a way to test it through techstream or in the manual. The manual links are in @Ultramaroon sig.
