I had the same code for my 2019.
i was using the 12v outlet, charging devices from a separate inverter , without the vehicle running ( trying to save fuel) I guess I drained the vehicle battery down too much. That’s when the engine light came on with that code. I now use the factory built in inverter that came with the truck. 1 outlet in the dashboard,the other in the bed. This set up works only with the motor running. So while I’m driving I charge everything then.
hopes this make sense and help out in the future..
p.s. I cleared the code myself, never came back on since. It’s been 8 months and 15k miles.
