Hard to believe but it could be a low aux battery still. Did you put a 12V charrger on it to top it up, even though new they are fully charged. Maybe even a cheap multimeter from HF would help so you can measure the actual voltage.
P1A10 On board charrger power supply relay circuit, low input voltage
U1111 is a CAN buss code, Display CAN Timeout or Not Installed.
Have you changed out or been messing around with anything in the car such as radio or center nav system display? Generally CAN buss errors are the result of low or missing aux voltage, but it could be a valid fault if you have left something disconnected.
