So I dont know if any of this is part of the cause or just a coincidence but this weekend I was on a 800 mile road trip and on my way home I had the cruise set at 75mph. As a crested a hill and started coasting down it started to rain and simultaneously the ABS, Traction Control, and Service Stability lights came on and have stayed on for the last 5 starts. What would cause an issue like this?

it could be numerous things that will set that off. from the sounds of it you may have gotten a little water in the plug for one of the wheel speed sensors. unplug each one and put some dielectric grease on them and plug back in and see if that helps

So today I was under the car putting in a hockey puck motor mount and decided to look at the hub on the drivers side where I put in a new CV shaft and I think I found the problem. The outlet that comes out of the hub is missing with some severed wires and the plug looks melted like it has been rubbing against my tire. Guss I need a new hub now. On a high side the solid motor mount makes the car shift awsome. To think all these years I thought it was my PCS going out. owell, live and learn.
