Drive though any deep water lately?
Shift motor on T-case could be full of water making is have a mind of its own.
Faulty switch, Integrated Power Module to list other possible causes.
Getting the DTC's read at the dealer should be your next step before something gets damaged.


Thanks for reply, it has not been in any water. Another question, is the shift motor hot wired and cabin switch a ground or the hot wire goes throughout the cabin switch to shift motor?
