Check Engine Light 2016 570

Hello, I have a 2016 Polaris Sportsman 570 and a couple days ago the check engine light came on. After doing the diagnostics, it came back with the SPN code of 168 and FMI of 3. According to the book, this means that "Voltage is above normal, or shorted to a high source." Recently I went through some deeper water and didn't know if this could have something to do with it. When I bought it I also put an aftermarket wench on it, but that was back in August so I doubt this has anything to do with it. Any suggestions would be appreciative as the warranty has ended and I have no idea where to even start to look.

Something else that might be worth mentioning is that when I rev it up, the LEDs that show the check engine light MPH light(etc) and backlight of the speedometer all go out. I have a video of it doing that here -->
