Anyone get ESP fault after washing car?

). I actually washed my car on Monday night and it sat all day Tuesday and the message was on when I drove to work this morning. I checked with my code reader and there weren't any codes, but I believe these code scanners can only read ECM/TCM codes. After I restart the car the warning goes away, but I think only after the car is warmed up a bit (I can't remember for sure how it was last time). I don't know if it happens in the rain because I don't drive my car in the rain. Has anyone ever experienced this? I've still got CPO warranty for another year, but I don't want to have to have the dealer get the car wet to diagnose this because I spent about 8 hours on my paint getting it darn near perfect.
Have the dealer confirm your VIN is included and the campaign has not already been completed the repair in its entirety will be at no cost.
