P0535 - Rear AC Evaporator Temp sensor circuit failure
P2612 - AC Refrigerant Distribution Valve (Battery Zone valve) Control circuit low
The P2612 is the most likely cause of the EV mode not coming on. If the battery is not cooled then it will fail so when this code comes on it disables EV mode so that this doesn't happen.
I attached the testing that we need to run through in order to figure out the issue. However, we most likely have a circuit issue due to the other code that you have. If you fix the P2612 then I am sure you will fix the other as well.
Let me know what questions you have. Thanks
