Got contacted today by the owner of an CTS 3,6 -05. Only 15k on the odometer. The car has an issue: No contact whit CPU and key!

He took the car to dealer but they could not solve it. Charged him almost 1000$ for the search........

I do not have any codes yet but maybe someone has a idea anyway?

BTW. Does the CTS -05 have built in code reader like STS?

Diagnostics: I believe the 3/3.2L CTS did have diagnostics but 3.6L did not.

Issue: no contact with cpu and key! i don't understand, can you explain further?

No, I can´t give a good explanation. This was what the dealer had told the owner. Very surprised they can´t diagnose the problem. All I know is that the engine don´t turn. I hope to come back with codes.
