2022 t880 diff locks

Got a 2022 t880, and a new question.
Do these trucks have diff lock indicator lights?
I tried to use it yesterday and no lights came on, and it did not work. Both switches on and still one wheel peel.
My 2020 had them.

 

Trucks were ordered with diff and interaxle locks.
This one has no power going to cb either.
Plus it looses 75 lbs air in 12 hours overnight

 

We waited over 2 years for these truck to be built after ordering them due to the scamdemic

 

i am going to try to get to dealer tomorrow if it rains like the weather doods say it is supposed to.
i will let yall know what they say.

 

6 freaking hours and all they could tell me was there was a blown fuse in the fuse box.
nothing was fixed because the chassis number is not coming up in the computer so they do not know how the computer is programed to change the settings.

although the guy that brought the truck out of the shop told me he "thinks" the diff and interaxle locks are not working because the air dump is engaged. he told me to try filling the air bags before using them.
which makes no sense because i turn pto off and wait for the truck to raise 3-4 inches before moving away from the paver.
