Saturday while out driving some trails west of Houston I really only needed my high range transfer case gears and for a few hills just shifted the transmission into 1st or 2nd gear. Since I have not gotten out in the brush for awhile I thought I would shift the T-case into low range and use the Hill Decent Control. I moved my T=case lever forward and it felt as though it engaged but I quickly got the Transfer Warning Neutral lamp on the instrument cluster; it looks like 2 bear cog rings with an X through one.

Not wanting to hold up some other rigs behind me I just went back into the T-case high gear range and continued on.

Not sure what I did wrong.

 

Sounds like it did not make it all the way into the low position.

 

If the light is flashing its just not engaged. Sometimes it needs a good push or let the truck move a few inches to Lin up the gears.

 

Where you able to move when that light came on?
For what it is worth, playing on a dirt road is not the best way to test the Hill Decent. Find the steepest, sliprest hill you can find then while in low range shift the tranny into 1st gear and drive off the side of the hill, then you will see how it works.

 

Yes that must be it, the light was flashing and I think a tone was ringing. My area of Texas is pretty flat so I don't often get the chance to use the low range TC gears especially when it is as dry as it is after our long hot summer.
