Won't start / electrical issue

[depredos]

good time of the day folks)

gonna be short as possible. My Jeep Gladiator 2021 3.6 v6 had been a little water-flooded inside. Ripped off all interior to check all pins, mostly all good and sprayed with contact cleaner. So at that moment issue is looks next: Firstly With key FOB can not open doors. After when I inside the car, (lights interior and exterior works, dashboard and screen pops up after few sec. shuts down) on the dashboard shows as normal "brake + push start button" but after us i push the brake as i remember on the key start button light on "off" yellow but that time nothing happens. Thought that key Fob not recognised but if so dashboard need to show "key fob not detected". Also wanna add, i've checked aux battery, as expected it was down. so due to video's recommendations removed fuse 42 and remove minus aux battery cable from main battery, but in that case as normally electricity need to work, when put minus like a "AUX delete regime", but in my case nothing happens.


if someone know what can be an issue, let me know.
thanks in advance

Your key fob not working is telling me at least the Radio Frequency Hub module is not working. That is inside back wall under the rear window.

Does the start button cycle through and show "OFF" , "ACC" and "RUN" in each position and light up?

Attached is the starting diagram. The push button start is called the "Keyless Ignition Node Module" on the diagram. The RFH is the gateway to everything else in the starting sequence and you have to get that sorted first. Really going to need a high level scan tool to monitor the PIDS and see what is talking what is not. Ringing out wiring and shotgunning parts is only going to take you so far. Even then you may have more going on besides the RFH.

I will be honest, troubleshooting this over the internet is going to be a bitch. Water damage just makes it 10X worse.

How high was the water line? and how long was it in the water? its possible that some modules are not waterproof and water actually got in not just the contacts.

What do you mean nothing happens? No lights or indications. Or the same situation that you started with? If you have nothing, it could be that you removed the fender ground from the main negative and not the aux negative.
