ABS warning light came on. ABS module has a humming noise after removing the key. Had to disconnect battery to stop the noise. I'm thinking module needs to be replaced. Pulled fuse, seems to be fine. If a wheel speed sensor was the cause of for the ABS warning to be on, that wouldn't be the reason that the module continues to run/make noise after vehicle is off, would it? Thanks!
