You've probably already discovered this is an EEPROM fault, you either need to replace or reflash the EEPROM (Canon P/N QH8-0258) but I don't think the BJC-85 firmware is in the public domain.  You'll either need to get Canon involved or harvest a working chip from another otherwise dead machine :(

One of those "not economic to repair" errors I'm afraid.
