a GM service info went out on this a few months ago. From what I am told, the 2011 LS engines were included, but do not know for sure. Most are purchasing a spare PCM for flashing a new tune and putting in the original if a warranty problem occurs.

After repairs on any On-Board Diagnostic (OBD) II-related systems, technicians may find that some Inspection/Maintenance (I/M) Test DTCs that are stored will not clear.

I/M Test DTCs are different than traditional current and history DTCs and are used in certain State/Province vehicle emission test programs.

The rollout of I/M Test DTCs began in the 2010 model year and will be completed by the 2013 model year.
Vehicle implementation is by model and engine, so not all models will be updated at the same time, depending on engine option.

I/M Test DTCs cannot be cleared using a scan tool or by disconnecting power to the control module.
