Those codes are all CAN communications issues.
Either the ECM is toast, or you cut some wires, or a connector loose.

Is this a US spec car?

If it's not replace any LED bulbs you have upgraded, back to stock.
Disconnect any HID replacement, and return to stock.
Then scan, and see if the codes disappear.

If this works, Ill then explain.

Why change the led back to stock? What will it do?

Restore the correct/proper voltages, signals, and wave forms that the ECM is programmed to look for..
Read the FSM

Ok I understand completely thanks this was so much help!👍🏾 As I’m having a issue with the fuse blowing and it didn’t happen until I changed my battery. Codes p010c and u0101 after a water pump was changed but my battery went bad at the same time I checked all the grounds but no check engine light yet but codes are stored.
