These codes come up when there has been a voltage drop in the system, the Hybrid motor is going out or someone disconnected some wiring and reconnect it without the proper protocol.
Lets check the 7 fuses and one relay that runs the system first becasue that would be the easiest fix.
I have heard in the shop the transmission gear position switch can go out causing this problem as well.
Here are the wiring diagrams for the system and the hybrid safety switch to cut the high voltage if you want to do some testing. This system has 300, 42 and 12 volts at various components.
Check out the diagrams (Below)
Let us know what happens and please upload pictures or videos of the problem.
