Have you tried disconnecting the battery for a few minutes then reconnecting it.

Whoa Bob this is an 05, doing that can corrupt the BCM.

Is the security light on? if so you need to reset it, that information can be found in the owners manual.

I doubt that disconnecting the battery will cause any issues. How are you supposed to change batteries with out disconnecting them?

You use the preset saver tool, I have a nice one that plugs right into the OBD2 port.

I understand that, but not everybody has one. The OP's car came out in 2005 and the preset saver tools were not popular then so when replacing the battery you just disconnect it and installed a new one. I am thinking since he started his vehicle before the ETAC self diagnosis was complete, disconnecting the battery may reboot the system allowing the vehicle to start.
