2011 International 4300 Electric Problem, Abs brake light, Limp mode, Truck Wash fail, Maxxforce DT

Washed our 2011 International 4300 and it died right at the truck wash bay. We have had similar "brake" problem on the road, where it would start flashing all kind of lights at us, make us stop and wouldn't move. All that was after I replaced master brake cylinder, but I could never figure out what causes it out of the blue, this time it revealed that all that was a small rubber seal on connector. Watch and comment.
