Hi. I have a 2002 f250 superduty with a v10 in it. whenI turn the key to the "on" position the ABS module on the front left side, by the fender, makes noize. It sounds like alittle electrical motor trying to start.Thats the best way I can describe the sound. It only does it momentarily and then stops. It also does it after I start the engine. I used to own a 2000 SD and it never did this. There are no warning lights or anything on. Is this normal for the 2002s?
