Default B2158 and B2168 Fix

I have a 2015 Slim and my fuel pak is showing B2158 (right rear turn signal output low) and B2168 (running lights output shorted low). My right turn signal is out (bulb is perfectly fine), the LED for my fuel level no longer illuminates, and the check engine light doesn't come on showing the codes there is just a red light on my dash. I have checked the wiring and there are no issues. Has anyone run into this before? I have spent hours searching the web and have not seen a single fix for either of these codes.

You say there are no wiring issues, but what do you mean when you say your right turn signal is 'out'? If it's not working with a known good bulb, the wiring is suspect. Wiring problems, particularly grounding problems can drive you crazy. It's best to be methodical and go through everything with a multi-meter and even write down your findings as you go. FWIW, I have had a 'known good bulb' cause problems. It had some kind of a manufacturing defect and brought a partial short to the party. You could post more details here and chances are good that you'll get some good ideas on further things to check.
