Tips to Clone Citroen C4 BSI Module with FVDI

 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?)

 

Answer:

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.

Tools required:

Diagbox

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.

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!
