Will reprogram and a switch add hill descent contro?

[Ricomann]

Hi all,

I am historically a hard wheeler. Interested some trucks that are not Rebels (like Longhorn and Limited). Most I find have no rear locking axle/hill descent control. Those that have the Off Road Group (ORG) usually have both of those options.

I recently came across a Longhorn in good shape, good color combo, all the options minus air suspension, and with a locking axle button (so I presume ORG installed) but the hill descent control button is absent.

Does anyone here know if one can activate hill descent on trucks like the Longhorn with the ORG, by merely adding the switch and updating the software setting?

You could option the electronic locking diff without the ORG. If it had the ORG, it would have hill decent. As far as adding it after the fact, I'm sure it's possible, just not sure if alfaObd or Jscan can do it.

Maybe @Jimmy07 could answer that

Any good spots to research folks in the know with AlfaOBD/Jscan? I'm just learning about them.

There is an entire thread here about both

Thread 'AlfaOBD Known Changes 5th Gen'

Feb 11, 2022

I saw this being mentioned in the AlfaOBD thread that it would be nice to have a comprehensive list in one thread of known changes that are known to work, so I figured I would kick it off and add what I know and update to the first 3 posts that I will reserve for future submissions. I come on this forum pretty frequently and am an Alfa user, and thought the idea was a good one.

Credit to @Swicago who said: "There really should be an AlfaOBD main thread in this forum, with sub threads for each of the items you can add/change. Searching this giant thread is becoming a pain in the...
