Ony adding to this ancient thread for benefit of someone who had searched for these symptoms and looking for the cause. I had many of the same codes AFTER I removed and re-attached the connector for the ABS pump. I was getting the traction and ABS, DSC code, on dash but it seemed only when wet out. I reasoned a good shot of WD-40 on the connector would help it. WRONG, it caused all the above faults, wipers, radio, air bag etc.

Since I just had the connector apart I went back to it and re-seated several times to no avail, finally blew the connector out with air gun attachment and put it back together. Faults cleared and the ABS, DSC has not come back on since re-seat and lubing the connector. It seems to me the connector is a touchy area. I would not have suspected that a little WD-40 would have caused the connection to fail. I reasoned moisture was causing a poor connection as it happened more in rain than any other time and WD would help. Too much
