Hello
I was looking for a similar topic and unfortunately I did not find it on the forum.
I would like to present how much I was able to determine.
And also ask for entries if anyone in this topic has something interesting.
Or information about similar BSIs, e.g. FL5
Below I present the readout of the eeprom BSI EL5
used in the new CItroen models
For example Picasso II, C3 III, Aircross and probably others.
I made the reading with UPA-s
but it was not without its problems.
BSI was purchased on a popular auction site and, unfortunately, in the first phase, despite the correct connection, there was no data in the reading - only FF
After separating the boards and desoldering the 95128 chip, I got the data
It is also interesting that in the diagnostics on the table, the processor clearly did not load eeprom data (i.e. VIN and coding), there were question marks in the place of VIN number.
It was possible to enter the VIN and it was active but only until the power supply was disconnected - i.e. the processor did not program the eeprom either.
After many different attempts, the decision was made to replace the eeprom memory with the new 95128
At this point, the BSI recovered.
The UPA read all the data previously read outside the system very nicely after the pads.
You can perform eruptive reading operations, erase clones after BSI pads without dismantling the discs.
I do not know why this was the eeprom state ..... maybe it is a protection against reuse .... I will still test it.
It is a pity that the first reading could not be made in the system, but some came from the car after a specific crash (checked after the VIN read, the car is described as dead and in the photo you can see that on a specific roll)
There is an inscription on the BSI housing: Do not use if dropped
Maybe it has to do with eeprom blocking ... or maybe it's an accident or someone on purpose.
I throw in the connection for UPA and PINOUT BSI for diagnostics on the table.
I will only add that I have read and programmed in the system using the UPA as 25C128
for a simple reason - up 95128 is not included in the set

Moderated By T5:Good job - keep it up.
