Error E196-404E

My printer canon ipf6400 display shows error E196-404E. Looking the error list corresponds to "EEPROM read error". I have been reading about it and recommended solutions are:

1- download firmware

2- clear error in service mode

3- replace main controller PCB.

I don't know if I have to execute instructions in these order or if one of these will solve the problem before execute step 3. Please if there is a solution without buying a new replacement for the main controller PCB i will thanks a lot.
