Cleared Codes....3 codes came back up but no check engine light....


I had a check engine light before and it was something with the maf so I unplugged everything and replugged them back in making sure it was tight and the light went off and everything was fine. When I did that...I also reset all the codes on the dic.
Today after I drove the car...everything was fine-no check engine light but I still looked to see if there were any codes after I reset them just a day or 2 ago.
And these 3 came up:
u1096 h
u1064 h
u1016 h
since the H is after it...its a history code but I reset everything so is this a problem?
The codes mean:
Loss of communication with PCM
" " BCM
" " IPC
So do I need to worry or is everything ok???
Thanks
