My four wheel drive all of a sudden stopped working it just says service four-wheel drive

4wd switch not turning on no lights just off

The push button start isn't working, it says that 'trailer brake service' is needed, also a code is flashing for 'four wheel drive needing service', But it won't actually turn over, won't even try and start. I push the brake in, then push the button to start it, and it'll turn the accessories on, I push the button again and it turns it to "run" but it doesn't actually start. The dash just flashes a couple times and then it turns it off.
I'm currently stuck in a parking lot so I'm definitely open to any advice, that being said I've tried...
•changing the brake light switch
•Changing the key fob battery
• doing a "hard reset"(disconnecting the battery for 20 minutes)
•jump starting it
•examine fuses for any obvious damaged ones

No front lights air not blowing cold no 4 wd it locks inpark and stay in low gear when I take off 56000 miles realy it's still new

Traction control abs and four wheel drive service dashboard turn on when driven on a high way.
