Yea im lost on this one the transmission even goes from sport mode to manual mode when im in low range but no hdc. I dont no if this has anything to with it or not but my cruise control doesnt work either I have checked over the basics such as fuses and relays havent worried to much about the cruise control as I wouldnt get much use out of it anyway.
Then you shift into low range and it goes into manual mode, correct?
If those 2 things are correct then I would have to say that you either have a brake problem and one of your warning lights is burnt out or the bulb is removed or you have a SLABS problem.
As for the traction control it sounds like you have a bad wheel speed sensor or 2, maybe thats why your HDC wont work either.

Hill decent control refues to work.
First thing I do is put vehicle in low range then move shifter too 1 and decend hill. The only thing that happens is that the green light continues to flashes along with a continues audible chim but no brake assist. Everything else is fine no warning lights of any kind. also with center diff locked should traction control work on all 4 wheels on my latest off road trip I noticed that traction control would only work on the front wheels as the position I was in left the wieght of the vehicle on the drivers side rear wheel but I could not get that tire to spin.

So that fact that you said it chimed, could be your LOW is not fully engaged. Make sure you push it forward all the way. Sometimes when it is not used often or when it is cold, its a little tight and hard to move.

i agree Torancis, I've never had a vehicle with HDC and boy does it change the game for off-roading.
sad thing is, i bet 50% of the Discovery owners out there never engage HDC once (or for that matter, even lock the CDL).
that being said, I still trip when about to go down a steep hill with the foot off the brake pedal. i'm constantly looking back and forth...first gear, check...HDC engaged, check...alright, let's do this.

Yes spike555 I normaly drive in sport mode the when I select low range it then changes over to manual mode allthough it does take a while. I dont believe there is anything wrong with the warning lights because if my center diff is locked and I turn off vehicle and restart my tc and abs lights come on disableing my tc and abs.
