Ficm voltage test question

Hello all, I am very new to the powerstroke community and am hoping to get a bit of clarification on something. I am having a hard start/rough running issue with my truck at the moment. I do get both a p0261 and p0270 DTC. My first thought was a possible ficm issue so I started the test procedure. I do get a solid 48v in all three test segments: KOEO, cold cranking and idling. My question is, with it passing the three voltage tests, can I reliably rule out the ficm as a cause for my issue? Any help would be greatly appreciated. John

Good advice from kinni, the likely answer is that yes you can still have a problem with the logic side of your ficm. With the two codes you posted, they are related to the plug closest to the firewall on your ficm. Check to make sure all the ficm connectors are seated firmly.
