2nd Gen Prius P0A94-548 DC/DC Converter Performance

Can anyone provide more info on this error code?

I believe I may have damaged my own inverter when I was charging my 12v battery. I usually disconnect the battery when I charge it.

I had just replaced a few modules in the HV battery. It took me about 3 weeks to get everything fixed.

The 12v battery ran down for some reason. So I was charging the 12v battery. I decided to running the TIS Software looking to Clear DTC's while the battery was charging. I figured the battery had enough charge and the charger would top off the battery. I was mistaken. I guess rolling down the windows was enough to kill the battery. The power ran down on the battery and the lights on the dash began to pulsate. I tried to turn the power off but the dash was "frozen" on.

I did it again after waiting an hour for the car to charge. Same issue. So then I ended up charging the 12v overnight. And the next day I drove it around and then got this error message after about 2 miles.

I was hoping someone could give me some info on what my options are to fix this issue. If not, I'll have to subscribe to TIS to get more info on DTC P0A94-548 DC/DC Converter Performance.

Not sure if anyone cares about the parameters for this DTC, but here they are.
