Charge the battery fully using the trickle charger, then pull battery terminal for 20 min to reset everything. When the car boots back up I suspect you'll be clear.
It cleared after turning it off and sitting for 15+ mins, but I believe I had this issue because I was driving it in pretty bad rain, and this was the day of me receiving the car. So I didn't know what was going on, but now that you mention it, battery could be weak. Thanks for the heads up. Do you know what type of battery this car has by chance? (You know how trickle chargers have different settings for different batteries)
