Mojave Locker Question

[Sah3167]

Just got my 2020 Mojave and have been reading that in 2021 and 2022 they updated the truck so that you can use the locker in 4Hi as opposed to just in 4low. Unfortunately I have the 2020 and can still only get the locker activated in 4low. My question….is there a computer update or something that I can do in order to lock up in 4hi? Thanks in advance

Let's first make sure you've prepared your Gladiator to know it's OK to turn on the rear locker:
1) Shift to 4hi
2) Press (and hold—for 3-5 seconds) the traction control button to turn all stability control systems. Press the off-road+ button to turn on off-road plus.
3) Press the off-road+ button to turn on off-road plus. Press (and hold—for 3-5 seconds) the traction control button to turn all stability control systems.
4) Lock the rear locker

If that doesn't work, then we're back to your original question ¯\_(ツ)_/¯

EDIT: Swapped 2 and 3 (reminder courtesy of @PW45)

Otherwise with a tazer you could.

BTW - The latter years Rubicon models have the same feature. Off road plus is the key.

I have tried all of the above and unfortunately still can’t lock in 4hi. I have read that they updated that in 2021 so am seeking what the “update” was and if I can flash the comp to make it happen. Thanks for everyone’s input

Here is the service bulletin to flash the DTCM. Bulletin Number 08-030-21. If you want a copy of it private message me your email and I will forward it to you.
