YAHOO!! S80 ABS messages and no re-start fixed

[uncletom]

YAHOO!!!!
Been over a year of scratching my head and reading all I could find. My ABS problems finally figured out. If you have all the abs, brake, traction and spedo and tack going down and trouble with re-start without disconnecting the battery for a re-set this is what cured mine. after a year of not hardly ever driving the car I pulled the air box and checked the connections on the ABS for a bad connection. The multi pin plug is almost impossible to mess up and you would think the small 2 wire would be also, but the connection was an open. The plug was pushed all the way in but one lead had an open circuit. after 10 years and the plug not being sealed there was a slight amount of oxidation on the connections. After cleaning the plug as best I could without a very tiny brush, a small amount of dielectric grease I plugged it in and out a few times, re assembled the filter box and put it to the test. Ran one tire on wet grass and other on gravel and what do you know, NO SLIP. and after about two weeks no more messages came back on. After one ABS repair and two other in to test Volvo still insisted I need a new controller. I doubt they would have ever found this problem as it looks so simple and easy to connect. In my opinion the design being a vertical F Male socket and no seal to keep moisture out this is corrosion waiting to happen. Repair takes maybe 30 mins.
Sorry for the new thread but I know there are others on the board with the exact same symptoms.
