Going to need to know more about your car and mods however here is what we know
P1871 - Transmission Mechanical Transfer Case 4x4 Switch Circuit Short To Battery,,, U0100 ...Lost communication with ECM
I have seen this with loose wire connections to the trans check all your connections
Have you messed with anything under the hood lately or with the center column?? there is a TCU connection box under the cup holders (SE and MR) that people sometimes forget to plug back in if they are in there....
