Hi all,

I have a Fiat 500C, 2011 year, with original BCM damaged. I bought another but with different partnumber (I didnīt found the same partnumber).

So, the problem: original BCM has 93C86 EEPROM, new (used) BCM has 70F3632 MCU. I have the files from both (in attachment). Now, the solution is make the new virgin and program new keys? someone can make virgin, please?

Thank you a lot

Requires NEC Dflash and Pflash new 70F3632.bin

Is necessary read Dflash and pflash from new BCM? Do you have pinout for this? I have xprog, IM608, for example.

And to read this MCU the data will be lost, no?

Thank you

That's how you should read it ....

So, in your opinion I should read the data (and the data will be lost) and after post here? Can you will help me, replace dflash and pflash with data from 93C66 of old BCM? If yes, itīs great! :D

Can you tell me pinout to read this? IM608 only has pinout to read 70F3379...

thank you a lot!

Sorry by no answer before!

I will try buy a BCM with the same partnumber, because I was no able to read NEC...

why you didn't think to verginize your ecu and work with the new bcm data may be sould be better solution

bcm with 93c86 and new with nec are not compatible, if you check it in nec bcm you have a blue connector and not in the original, that connector is gray, you must look for the same model, it does not matter if it is a different part number, but check connector colors.
then you just have to program a new transponder and virginize the ecu.

dont forget give tanks if i can help you
