Here is that I read from MCU hc908az60 eeprom is correct?? and hc912d60

[bidu20]

just replace the processor with a new one and program it with your old file.

UPA can only r/w eeprom from AZ60 so i suppose your flash is wrong... This is old type 8h62A MCU and you must read good flash to transfer it to NEW 2j74y. What label do you have on HC12 big procesor ??
When dash is dead heat up 8h62A and check if it comes back to life.
