Bringing this back up for a follow up question. Will the truck go into ad-hoc regen on very long downhill runs like through the mountains?
I smelled a little bit of smell on the first regen that smells somewhat alarming...almost like electrical components overheating much less than exhuast or brakes or something like that. I dismissed it as regen.
BUT....on a recent 2500 mile round trip I could tell when the truck was in regen on flat ground and never smelled anything in the cabin like i did on the first regen, however when the truck would go downhill for extended periods of time the smell (again best described as electrical fire) was VERY pronounced. and would go away immediately following the decent, almost as if it wasn't really in regen at all.
thoughts?
**edit** downhill runs were not in tow mode so it wasn't jake brake, and my application of brakes was sparing at best, they were not hot esp with air temps in the 20's and 30's.
