I had volvo scan the computer and they said the computer was not communicating with the ABS module. At this point I am thinking whatever is causing the speedo to drop out is also causing the ABS light to come on. I have not been able to find that the two have anything in common so I think the wires may bedamaged some were. The problem use to come and go but now it has been locked in for the last week or so. I did see on another site that someone had the same problem with the same make, modle and year car about a year ago but there was nothing posted as to what was found. I tried to email back but have not received a reply.
