4low blinking light/tight shifting/Cruise control wont set

Hola my Runner peeps! Question. I was out running errands this morning and all of a sudden my 4low started blinking. I haven't used 4h in while and have been driving with no issues. Having said that, when i shift into gear, its been tight. I thought I was imaging things..but nope. Also, cruise control will turn on but not set. I'm assuming its because if the 4l blinking light. Any thoughts? Was good on my first leg out this morning...just on the return it started.
Thanks for any insight!

Try shifting into low range and back out. Ultimately a proper scanner than can talk to the 4WD computer is needed to see what code is being thrown. A regular scanner won’t do it.

 

Same issue with my 2015… was the neutral safety switch. I sprayed PB blaster on it a few days apart, it’s been fine since

 

Neutral safety switch. In a few more miles of driving, your check engine &"See toyota dealer " will light up on your dash. Seems to be an issue lately. It happened to mine at 33k miles. was covered under warranty.
