Well, I listened to mine this morning at start up, and it doesn't make the noise anymore. I have flushed the brake fluid recently, so I don't know if that has anything to do with it. I know for certain mine USED to make that noise, like the ABS system was going through some kind of test, but I can't remember when it stopped making the noise. No lights on the dash and haven't had a situation since last winter to use the ABS or TC, but I assume they work.
