Not engine related, but I think I'll receive more help here that in the Trans or Misc sections as they are mostly cars. I have a guy that converted from a NV273 electronic case to a NV271 manual case and now has the "Service Transfer Case" light. Anybody know if this is stored in the PCM somewhere of if its in the BCM?
ECM I think, possibly in the TCM as well
Thanks for the reply Jim P. 6-Speed manual so no TCM.
2008 2500 4X4 6.7 I-6, 6-Speed manual. Anybody want to take a look and give a suggestion? I see a P0700 Transmission Control System set to Type 2. Could that be it?Attachment 94521
Best I can tell you need access to ram memory to ?switch off? the electronic transfer case control (unassign switch address). Accessing ram memory can?t be done in any regular tuning software. 2007.5+ calibrations have very limited information to find in regards to the transmission and transfer case, a lot of testing and trial and error locating that stuff.
