hey mate i have the same sort of problem on my r33 gtst the abs light comes on sometimes and also it sounds like the abs module keeps running after i turn the car off it has a slight humming and vibration, if i turn the car back on for a minute and then off the noise goes away, any ideas what this could be, the brakes seem to work fine i havn't had to slam them on yet so don't no if abs is even working. any help would be great cheers
