Your videos are amazing & I am grateful you have shared them with us! It’s hard to find good information for this problem! I have 2013 Hybrid Optima with Charging & Hybrid System Errors shut down system so can’t drive since it doesn’t charge 12v. Replaced so many parts but still have my problem, I am convinced it is a simple wire or short somewhere at this point. 3 codes are AC - U0298 “Lost Communication With DC/DC INVERTER” Active Air Flap - U0298 “Lost Communication With DC/DC INVERTER” Engine :P0138 for 02 sensor
I have advanced scantool and it is failing to activate my EWP. I am wondering if the Water Pump or The Oil Pump is potentially causing the system to shut down.
