    Default MB vito 112 cdi dashboard problems with MC68HC908AZ60

    Hello, I have a fairly classic problem on my dashboard vito model 638.
    HW : 35-99
    SW : 42-99
    ?P : MC68HC98AZ60 - MASK : 2J74Y ? the pre-serie version of the MC68HC908AZ60

    Speed, fuel and engine temperature gauges no longer work.
    The rev gauge is ok.
    When I warm up the MC68HC98AZ60 the dashboard re-operates.
    So I desoldered the μP and I read it with ETL at cold temperature and at hot temperature.
    I got two different files that differ from only 1 bit.
    I bought a new μP (MC68HC908AZ60 : not a Chinese version) and I reprogrammed it with ETL and the ?hot temperature file?
    The verify operation is ok. I soldered the new component.
    Now, I have the same problem as before replacing the component.

    How is it possible ?
    Did anyone have the original bin file for my dashboard ?

    I have find this version HW 30-99 SW 42-99_faild.rar and Vito 2J74Y_flash.rar

    And this one : HW 35-99 SW 42-99_faild.bin.rar

    thanks

    but freescale documents says : If the security check was unsuccessful, memory reads will return the
    same data "0xAD" for every byte read instead of the code or data expected.

    this not that i have
