...i'm experiencing a lot of trouble with my cts...it won't release the car key...the anti-deterrent theft system its always on, check engine light it's on, traction control it's on, and gauges will go off and all that for no apparently reason.
I don't know what to do...i just hope it not the computer, or any of the computers for that matter.
If someone has a complete wiring diagrams of any kind for that paticular model. Please share, i'd deeply appreciate it.

Sincerely

Jc.arias

Have you had the check engine code pulled?
