Can you try restart the car by shutting down MCU,disconnect fireman loop,removing negative terminal of the 12V battery & connecting back everything after 4-5 hours to see if the errors goes away also check the voltage on the battery if it is coming up more that 13V then your DC-DC converter might not be fault
