Jeep died, I don't know how it happened or what this even means. Called my uncle and he says it's fucked and likely they will replace it.
Does that mean I lose all my aftermarket parts?
Very bad day

My guess is you have a short somewhere. That’s a common one for FCA Jeeps with a lot of aftermarket electronics/lights added. If you have something that’s not grounded well, it can throw your ignition. If you can‘t find the cause, it may mean a new TIPM but I seriously doubt the entire Jeep will be a loss.

It’s the box that routes power in you Jeep. I doubt that it’s bad though. More likely a short happened and the onboard computer didn’t like something it saw. If you are handy with a multimeter you can probably track it down yourself. First thing I would do is unhook the battery for a full hour (no cheating, a full hour). Then hook it back up and see if that resets the ignition. If not, time to start chasing gremlins with the multimeter.

Check fuel pressure. Theres a VERY good chance it's the fuel pump, especially if anyone tried to jump start it.
JW is not wrong. This seems to indicate a bad TIPM or a short. If it wasnt starting, and you tried to jump it, it could throw this code because of the attempted jump, all the while being a fuel pump. So check that pressure first

You're going to have to better describe what it does and/or doesn't do.
I understand it doesn't start, does it turn over? fast, slow, normal?
What is the battery voltage(s)?
What was it's condition when it died? idle, driving down the road, trail, high angle,water, etc.
You're positive it has fuel? Positive?
Is the bottom of the fuel tank damaged causing a false reading or prohibiting fuel pick up? Is anything hanging under the vehicle, hose, etc.?
There is a set of high amp fuses in the TIPM that is closest to the engine. If someone tells you you need a new TIPM check these first.
Just disconnecting the positive and negative battery cable does not power down a JL/JT. There is a ground lug on the passenger side fender liner located between the Battery and TIPM , this has to be disconnected to power the system down completely (and despite it being a ground it will spark when you reconnect it)
Using your thumb push all fuses home in the TIPM, make sure they are all seated fully (not a single fuse was fully seated in my new Power Wagon).
Probably late to the game, but good luck

The engine turns but doesn't start.
Battery is full, 12.9
Scan says ignition run/start circuit high

Did someone try to give you a jumpstart? The answer to this changes the diagnostics.

If the code is B2102 there is lots of info on every jeep forum. Most common issue seems to be bad fuel pump. Even though the code is not technically for that. Check the fuel pressure at the rail. Could even use a little starting fluid and see if it kicks over to confirm the old school way. No death nails. Everything is an easy fix.

No. Do not have someone jumpstart. Just curious if that caused the issue apparently it didn't.
What year and engine etc. Do you have

The thought was there may have been a fuel pump issue but if that wasn't recognized, and it was jump started thinking it was the battery, that may have sent the code.

Jeep’s have a problem with the Knock Sensor going out. Your description sounds just like a faulty knock sensor, or camshaft position sensor (also very common on Jeep’s). Unfortunately both require replacement of the sensors…and both are a PITA to reach.
My suggestion is to sound out an S.O.S on here and your local Facebook pages to get help either towed out, or repaired on the trail.

I got it towed home.
Just don't know what this means. Tried clearing it, but nothing happens.
Glad you got it back home at least.
? I dont imagine it will clear if the issue is not resolved or if your scanner has a fault?
But as to what it means, now that you are back home, when you get a moment of free time, take a look at the thread with some fresh eyes. We found the official and several practical possibilities for you to look into
