Need to clone the BSI of a Citroen c4 because old one does lose communication and wipers/lights on/off when hot. Johnson Controls 96640591xxxx. Question: Will copying EEPROM to a BSI with same numbers be enough (got BSI with same numbers of a Peugeot 308)? Or do I need the flash too? (What’s stored in there?)
If signature of flash same so only eeprom is enough.
First read what signature have you got.
Also before playing with bsi print your telecoding of ori bsi.
FVDI (changed as SVCI)
fvdi will help you, please look at the following guide:
If you have FVDI (SVCI) you can also make exchange but it’s not 100% you need learn keys after that.
I do following.
I read flash with FVDI and read eeprom 95128 with programmer.
At last i write flash and eeprom in new BSI. Thats enough. It work 100% on Johnson BSI. On Valeo still need progam keys.
And bsi psa pinout to follow:
What about diagbox?
Replace the eeprom and recode everything with diagbox vf pin etc …
you can put your eeprom there but will have to recode via pps diagbox I have done it several times and it works perfectly.
PS: If flash is not same as ori….. virgin eeprom will not help you.
Alright, hope it helps!
