Canon 6D Back button auto focus and ISO settings

I was curious why when I am shooting in TV mode and I am using the back button auto focus that the camera will automatically change the ISO setting that I set. Is there something that I have missed in the settings or is this an automatic feature that can not be turned off?

Do you have it set to Auto-ISO?  The camera shouldn't change ISO otherwise.

No ISO was not set to auto ISO

In the Menu, Clear All Settings.  Try again.

Sounds like you have safety shift set in a custom function

 

Check C.Fn 1-6 Safety Shift - you may have it set to 2 - ISO Speed
