I'm looking for some advise from the electric/electronic experts on the forum.
A week back I was stranded in the Maze, a part of Canyonlands in Utah considered one of the most remote areas in the lower 48 states. Here is what happened:
We were camping in the Dollhouse area of the Maze for two days, during which the fridge was connected to my main battery and drained it. I had parked the vehicle in 4L.
No problem (I thought) and pulled out my Micro-Start XP-10 pack from Antigravity Batteries. Disappointingly, the XP-10 could not start the engine, It did jolt the starter a bit, but not enough to start it.
So I grabbed the jumper cable to start the engine with the help of our second Jeep, pressed the start button.
Something happened at this point, and the electronics ended up in an undefined state:
The electronics appeared to assume that the engine was running, it wasn't. It also assumed that I could shift into D, which was not possible.
We came to the conclusion that we need to reset the system, but how?
I could not find any information in the manual on how to do this. Jeep care was not reachable on a Sunday.
We finally decided to start pulling fuses one by one. We began at the lower right, fuse F10 (description is KIN/RF HUB/ESCL, see yellow arrow below) and immediately hit the jackpot:
So here are my questions

Something happened at this point, and the electronics ended up in an undefined state:
- The lights indicating Park, Drive, Reverse, Neutral next to the automatic shifter all lit up in yellow.
- The start button indicated RUN, and pressing it again did nothing
- A solenoid in the engine compartment was humming/hissing, potentially the fuel pump?
- The following error was displayed on the dash:

- the lights on the dash went out,
- the solenoid went quiet.
So here are my questions
- How did the electronics end up in a state thinking that there was a transmission problem and that the engine was running? Was it because the Jeep had been parked in 4L?
- What is the proper way to reset the electronics?
- What exactly does fuse F10 (KIN/RF HUB/ESCL) do?
