bsi JC problem

**Brof** · 11th November, 2018, 12:51 PM

Great explanation, Just a question on this, so the problem is when fvdi is been used to read pin code from Johnson control for key programming/learning? so by NOT trying to read pin using fvdi there wouldn't be a problem in the first place? Therefore why don't people get pin from other source or device first? then this problem would not be happening, Am i correct on this?

ON SOME JC BSI UNITS FVDI/AVDI CORRUPTS THE FLASH WHEN IT READS IT. IT WRITES A NEW FLASH TO ENABLE IT TO READ THE EEPROM, THEN WHEN IT TRIES TO PUT ORIGINAL FLASH BACK IT FAILS CHECKSUM BECAUSE IT IS CORRUPT & THEN LEAVES BSI DEAD IN BOOTMODE.

I don't believe adding power by jumpleads etc. makes any difference whatsoever as reported by others on here. There are just some versions of software that it always seems to corrupt. Even if you read the flash before reading pincode it will be corrupt.

THE FLASH IT READS IS STORED IN MY DOCUMENTS FOLDER / ABRITES software for ID ******/psa. This will vary slightly depending which version of windows you are running but look in my documents search for psa or maybe view by date modified & it will be obvious.

The problem is you need an undamaged flash at this point. There are some available on here & other forums. I have not been able to find a few anywhere. Do NOT write the flash or it will wipe the eeprom & need to be reconfigured.

My solution, tested & working 100% on numerous vehicles;

1. Find your flash id by opening bsi with fvdi & get 4 digit software signature. Then obtain a good file with this id.
2. Go to the file location & replace the corrupt file with the good 1. Make this file write protected. It must have the exact same name as the original eg. JCI_BSI_7F0B.bin
3. Perform the pin read again with fvdi & it will work correctly, give you the pincode then the car will come back to life. You can then program keys or whatever you wanted to do in the first place.
4. As long as you keep the good file in its location & write protected fvdi will always work ok for any bsi with the same software signature.

Hello brothers ,
I have made the connections in my table and I can now scan on bench BSI JC. To restore this BSI JC I need the flash "software signature 7FAD" can someone help me with this file to restore? The locksmith who was watching this car says he does not have the file backed by FVDI.
I hope someone can help me with this 7FAD file.

thanks for your help
