I have a 2000 ML320 that has been great! It has 40K, and I have my first issue. Three lights (BAS<ETS<ABS) lights come on after the car hits about 10mph. You will also hear a short buzz noise before it comes on. After you turn the car off and restart, the lights are off. Start down the road, you hear the noise once, and the lights come back on. Any ideas where to start?

Thanks
