I've found a lot of info on this error but nothing for my specific situation. Got back from a trip to Chicago and after filling up the tank I turned the car on and all of these errors popped up. I looked up what the probable cause was and ordered two front hub assembly's that my mechanic was going to put in for me. He scanned it and said the error was "EBCM" so he didn't replace the hubs. Is it still possible that the hubs are the problem, or does that error pretty much confirm that I need to replace or repair the EBCM? The car is a 2006 GP GXP.

Any help or input is much appreciated. Thanks
