Transfer case went into neutral without pressing the recessed button
I took my '13 GC Trailhawk Hemi to the top of a cell phone tower access road this past weekend. It has the Quadra Lift system and Selec-Trac, and I used 4HI going up. Got to the top and went to put it in 4LO to go up a steeper section to get turned around. Put the truck in neutral and hit the 4LO button. After a couple seconds the driver display said “4WD SYSTEM IN NEUTRAL”, and a little red light was lit on the selector. I put it in drive and sure enough, nothing happened. I shut it off and then restarted it. I hit 4LO again and it worked. I used hill descent control going back down.
Is there any way to get the transfer case into neutral without pressing that tiny button?
