How can I fix multiple warning lights on my 2019 Ram 1500 after hitting water?

After hitting some water in my 2019 Ram 1500 Laramie, my dashboard lit up with all sorts of warnings: "Service airbag system," "Service antilock brake system," "Power steering unavailable," and more. All the warning lights came on, including traction control and check engine. I’m not sure where to begin troubleshooting.

I had a problem that "activated" the same warning lights and warnings, but it was due to a melted wire which caused a short. I had to look at the wiring on top of the rear axle.

I hadn't considered that it might be a wiring issue. I'll check out the wiring on top of the rear axle to see if there's any sign of melting or a short. It could be something I can fix without too much trouble. Appreciate the advice!"
