focus 2005 dash cloning

[purdy]

hi all
just getting to grips with upa and MCUs so be gentle.
got a dead dash in a focus 2005. cant scan dash random lights and stuck guages non start.
i have SH dash same part numbers. was hoping to clone dash across to SH unit.
can some one check if dumps are good as i can see chassis number OK (WF05XXWPD55A08909) in epprom. but not sure where to find millage to check that. dont want to put a corruped dump in new dash
have read mc9s12h256vpv via BDM and i have three dumps one epprom.one flash and one memory map.
do i copy all across to new dash or just the epprom.

298724
298727

I'm learning fast with this stuff. but have questions.
what is a prossessor mask and what is its purpose 1k76x.
what is a i know flash and epprom are but what is memory map
thank purdy

how i did it was like this
read and save both dashboards files
flash and eeprom
program your old dash flash & eeprom to new dash and try it
worked for me many a time
but the old dash is probable dry joins mate
i reflow the full board
resolder the main connector and see if that does anythign
failing that the 9s12 will prolly need resoldering

Just been looking at the eepom. It looks like the same set of data just repeated 4 times through the dump. 1024 bytes Is this normal?

Compared the flashes these were the same so only copied EEPROM across to new dash. Did still need to sync dash and PCM together with ids to get car started. Found out from customer he was using booster to start the car. Thanks for help. Nice result
