Need help! Service ABS/TRAC/ACTIVE HANDLING
Hey, I just finished washing my wheels and engine compartment when I had to take the car for a quick drive. I didn't make it a quarter mile down the road when I got "service abs" "service traction control" and "service active handling system" flashing on my DIC. I pulled the codes and the only new ones were
C1234 LR Wheel Speed Circuit Open or Shorted
C1255 EBTCM Internal Malfunction
The wheel sensors on the hubs appear to be plugged in tightly. Is there something under the hood that I could have disturbed while washing it. I never had any of these issues before today. Also, where is the EBTCM located at?

Certainly a possibility. Hopefully, it was not a pressure wash. Troubleshooting a C1255 code by the book is a short event. In a nut shell, repair damaged wiring, if none is found, replace the EBCM. I would disconnect the battery, remove the EBCM connector, and blow it out with compressed air.
Good luck.

I was contantly getting the same warnings. Especially after washing the car. 2 months ago I installed new C6 Z06 shocks and when I had the wheels off, I unplugged the connectors at the hubs, blew them out and reconnected. I have not had a light or code since.
