CTS anti theft or imobilizer system

[CaddyGirl3]

Same problem here... However, not sure ECM will be under warranty with "my" 2004 CTS because car was involved in an accident.
We've already had one car that was denied warranty work because it was in an accident.
I guess time will tell....
My "theft control system" is an intermittent problem, too.
Intermittent problems are the WORST. *arrgh*

ANYONE GOT A 2004 CTS REPAIR MANUAL OR SERVICE MANUAL?
We've hooked the car up and some codes come up... but it doesn't go to the next step and say which devices to try to replace
and/or how to replace them.
THANKS

My 2005 is in the shop right now for a similar problem, not real sure what it is but as soon as I find out what the issue is I will post.

I outlined my problem in a thread 'Electrical Gremlin'
