4wd Not Working

Hello everyone, I was out coyote hunting today and my 4wd on my 2017 TRD Off-road starting acting up. The light is flashing and it won't engage in 4H or 4L. When I got home and was unloading my gear I realized there was a beeping coming from underneath. It seems to be coming from a part on the rear of the transmission case.

I'm gonna call the dealership in the morning but does anyone have any thoughts or suggestions?

I wasn't getting crazy with the off-roading or anything. The truck has a bit under 61K on the clock.

 

Sounds like it could be the actuator for 4 wheel drive. Try putting 4 wheel actuator in the search box and see what comes up.
