:mug: Do a search "Service AH/TC/ABS", you will find plenty of info! I had this problem a few months ago. It was the EBCM and BMPV. Electronic Brake Controll Module and whatever the BMPV is, I have no idea but they were both replaced under warranty. The EBCM is that little aluminum looking box I believe it is on the drivers side right in front or the altenator with the brake lines running into it. It took the dealership 3 days to get the part and fix the car and the total cost was nearly $3k!!! I have seen the same code's with other members that was something totally different than the EBCM/BMPV. This is a fairly common problem. I have read post's where people have bought their Z's brand new and before they roll 1000 miles, they get this code! You would think Chevrolet would just start to fix the problem for free or do a recall on it! Anyway, good luck!
