My wife started the truck just now and saw the service 4wd light on the instrument panel. Also noticed no lights above the selector switch.
I had her shut the truck down and rotate the selector a number of times left and right.
Restart and service 4wd is still there and still no lights above selector.
Does this sound like a bad TCCM or no communication to the module.
I was gonna start with pulling the circuit breaker and see if I can wake it up....
Any other things to check or suggestions?
Never had this issue before so it's a new one to me.
