Is there a way to disable the Reduced power mode? twice this has enabled since I tuned my trailblazer, it is not throwing a code but I do have some codes turned off so I am not sure what is causing it. I am wondering of it is the cooling fan. Last year it set the P1221 code a few times but has no this year that I am aware of. I am new to tuning so there is a possibility I did something wrong as well.
