S197 3V P2106 code

So my car shows engine failsafe mode. We have converted from a auto to a manual. But I don’t remember reading that message on the display. On Sunday we flashed the ecu to disable pats/vats and told the car it’s a manual. Today I was getting ready to move the wiring to the switch panel and bypass the factory key. We did save the origional tune, I will flash it back tomorrow to see if the failsafe warning goes away. I think it will. Any advice? We used hp tuners.
