The CCRM module is not in the way at all.....it is on the radiator side support.....next to the ABS module.
It contains the fuel pump relay....so if the unit is not connected, it would not run.
If this is your original CCRM, you might try replacing it.....if the IAC thing does not work.
They did update the unit since the vehicle was built.....better sealed relays in there....so I would not get a bone yard unit......as you would want to get the improved version.
The original issue that caused them to update it was a issue with the fuel pump relay in below freezing conditions.
I have pictures posted of the CCRM
I have replaced mine 2 times.....once for radiator fan issue and once for A/C compressor issue.

The first thing that comes to mind is the IAC (Idle Air Control).
As it is new, you could try cleaning it.....with SeaFoam "Deep Creep" (which is the spray version) or even WD-40.
