2012 isx codes

[resp59]

Ok, I have been out and not able to reply till now. The hillbilly tuner is the only thing I have to read the codes. It is/ was set on stock. But after sitting for 2 days with the power left on but key off, there are no codes. All of them went away by themselves... I haven't started the truck yet as the sensors and pipes are still off. Maybe there is such a thing as bad grounds that would do all that... guess I will check...
