2006 CTS when i run my car thru the wash within a few miles my abs and tc lights come on and the message service brake control is up. After a few miles i can shut down the car and restart and all is good. If its raining i get the same forever till its dry out. I got the codes saying the left and right wheel speed code. Yet as i drive all speed sensors are reading the same. Is there a connector somewhere that is a typical culprit or do i have strange issue. All wires and connections look fine at the wheel speed hub connector. Looking for any suggestions.
