Toyota 8FBCHU25 Error Code 31-1 & 31-3

The operator changed out the battery on a Toyota 8FBCHU25 60677 and the 2 codes (31-1 & 31-3) showed up on the display. I looked in the repair manual that I have but these codes are not listed. Any help and direction would be appreciated.

Thank you for your insight on this, very appreciated.
I found some corroded and broken wires that I need to address first. I am also looking into a new wiring harness in case this one is to far gone. I will definitely look into your suggestions if I still have a problem.
