Is My ECU Fried? Help!
My dashboard looks like a christmas tree. I have the follow lights on:
Traction Control, BRAKE, ABS, Check Engine, Antilock Brake and my push start button is glowing green while driving down the road. The DIC is telling me the following:
Service Active Handling System
Service Antilock System
Service Traction Control System
Service Fuel System
Service Engine Soon
My fuel gauge is showing ZERO.
I have had a flash done at the dealer a while back that fixed the service fuel system/gas gauge not working issue. I have also had a piece replaced some time ago that fixed a service traction control issue.
AND, now my ODBII gets a NO LINK when I try to read any codes. It has worked fine on this car yesterday and still works on other cars now.
Any ideas? I am at about 85,000 miles on my 2008 C6.
Thanks.

Nothing for sure but those symptoms show up when the battery is too low/has a bad cell. Have you checked the battery yet? Disconnect and hope for a reset? Seriously though, check the battery thoroughly.

I agree with RickT. I had the same issues with mine one evening. I had some of the same things flash on my dash, with the addition of "Shocks Inoperative" (I have Z06 shocks, and no F-55) and the "Theftlock" icon. My car would start for a second and then die. Luckily I had stopped in a large parking lot with nothing in front of me. I got a ride home, got my truck and trailer and got the car home. The next day I rolled the car off of the trailer into the garage, got in it and it fired right up like nothing had ever happened.
I had noticed that the battery seemed kind of low when I started the car on the evening this happened and also the next day when it started like nothing had happened. The battery was fairly new and under warranty so I went ahead and changed it and it hasn't happened again.
