Re-reading your post and the instructions above. Don't clearly understand initialised?

Finally having issues with the RR being non responsive to changes. Connects fine, verifies fine even with wrong file? So something is wrong? One thing that happened before this was turning on and off Lean Cruise Enable during a highway drive for data purposes. It would Enable, but never disable? Since the original note brings up COS, is there an issue with maybe a Cax file parameter as well?

Button options says: "Execute from PCM flash memory if fitted, else execute from RR?" So I tried and it will not flash through V2, looks to be locked?

If vehicle is running and I click this button the vehicle turns off! Click it again and vehicle will start without loading a tun.. So what is it's purpose?
