Always remember to return program to stock and remove it
5 min job
This will save you allot of headaches

First thing I did was return to stock to make sure problem wasn't edge related.

Edge doesn't go into your 4X4 system, but I would of done exactly same thing :icon_biggrin:

Will this also fix the slippage problem?

Depends what sensor is gone,
If I remember correctly there was a recall on 4x4 vacuum switch
my old truck had that changed out
and I didn't have any problems with it
Does your edge read any codes?
if not just clear all the codes just to make sure and than have a look if it comes back

 

[Smokefan]

No codes on Edge, but truck didn't do this on the way home this afternoon.
Could it be temperature related?

It has to be faulty sensor

Called local dealer today, they never heard of such a problem so now I have to wait til the problem comes back.
Figures the only time all winter that I can get away with losing the truck for a week and I can't get it fixed.

Wierd..
I know that my 4x4 lo light doesn't come on when I turn the s/w to that position..
Is that a problem?

Is it engaging?

 

[Viper238]

Is it engaging?

Yea 4x4 does engage.. I'll swap it too the high location and 4x4HI will light up..

but if I put it too 4x4 LO there is no lights on the dash..

 

[Smokefan]

With 4x4 lo, I don't see not having a light being an issue it's pretty obvious when left in 4x4 lo.
Probably just a burnt bulb.

 

[Smokefan]

Edge plugged back in, same temperature as Saturday but no problem now.
I know whatever this is probably won't act up again til month 37 of my 36 month warranty.
