Hey everybody,

I have a 2018 JKU Sahara with 21k miles on it. I've had it in the dealership for the last 4 days because my dashboard lights have been flickering randomly (happened 2-3 times in the last few weeks) and then the check engine light stays on. The dealership said that the OBD sensor said it was the U0002 code but couldn't fix the issue. I remembered that I had a Kenwood radio, speakers and an amp installed several months ago. I got caught in the rain with the top off and the head unit got wet. Does anyone have any experience with this? Could the radio getting wet cause the error code and the flickering. Thank for any advice.

disconnect anything that is aftermarket and see if your dash still flickers. I am guessing you have a short somewhere.
