ABS/ Skid Control System Service required' What does this entail ? S80 2005

In the little message window to the far left of the dashboard, this ominous message has appeared: "ABS / Skid control system service required". The last time a had to deal with the ABS was in a 2000 V 70. I took the unit out and sent it to someone who fixes them in his garage. He said it had a cracked circuit board. Where is the skid control system in this car? Is it inside the ABS computer? I must avoid the dealership because they will go to town on this one. When the ABS skid control kicks in, there's a slight rumbling in the brake pedal. That rumbling is now happening slightly and briefly when I take off on bare dry pavement. No error codes present except for low fuel pressure which means the fuel filter is clogging up.

You could go to the Xemodex.com site, but I would first find someone with a good Volvo scanner to find out if it is just a wheel sensor that is out of alignment or has a faulty wire.

First, no one has done the brakes, struts, rotors, a drive axle, etc., right ? If so start looking there. We had an issue with a loose sensor that caused all kinds of problems.

Bentley's gives a simple way to check the sensors to see that they are working. We have a V70 so I'm not sure the location is correct for a sedan. The front sensors have a connector behind the strut towers and the rears have connectors under the carpet beneath the rear seat. The resistance should measure the same for each wheel sensor. If you find one that is significantly different, that one is suspect. Replace it and see if the light goes out.

If they all measure the same I think a trip to the dealer or someone with a scanner is in your future.
