i jumped the termenals and 4wd lights flashed code2, i know its the encoder but i want to see a breakdown for it before i take it apart

 

Check out the posts in the Tech Article (DIY) section. All of the codes for the NV233 transfer case are the same so you can either look at the post by error_401 or the one by lastcoupe.

Different system. This is a TCCM code, not an OBD code.
