ou need to have your dealer check it out. I always turn the key on and wait till the computer makes its cycle before pushing the start button. Always did that on my first SS too and my wife does it with her's. Never had that code.
Also, WELCOME!
I used to do the same thing and that is how I found out where the check engine code would come up. I have never had have any issues with my power steering but I do not have any cruise control and my ESP Intervention fault indicator would light up. So I can not allow the computer to cycle now. I have to start it right away or have the issues.
