U0101 - lost communication with TCM
U0106 - lost communication with GPCM
Truck sat for a month or so without being started. Battery - 06 LLY - was dead - after charge, the truck started right up and ran great but had a CEL. Above are the codes that were pulled. They have been cleared, but I am new to diesels and I want to make sure that the codes were related to the dead battery and I don't have anything further to be concerned about.
