Ok did you do the reset procedure? If not do that just to see if it resets things. If nothing changes then we will have to test the stuff one item at a time.
Now we need to check voltages at TCCM harness (transfer case control module). With key on engine off you need to check for power at the following terminals. Refer to the diagram below ok. C8, C11, C12, C14, D14 and D15. Then check for resistance at C10 to ground it should be 2 ohms or less. If all it good then you will need to pull the 4x4 selector switch out and check for voltage at the pink wire at the switch. If all this is good then we will move to the next step. The diagram below will be needed for that too. Thanks and get back to me.
