ECU 0 281 011 421 Fiat - Flash 29F400BT problem - IMMO OFF

[Yhoni]

HI, I have a problem with the ECU 0 281 011 421 installed in a Fiat Stilo.
I am trying to immo off and I have desoldered the flash 29f400BT but every time I read it it returns a different result. I think the flash memory is bad. It's possible ? .I have been able to read this type of memoir on other occasions without problem.

So I need an original file of this memory, does anyone have imm off included?. Is it necessary that I also modify the eeprom ?.

Thank you.

Hello Volker, I am using a TL866II XGECU PRO reader, I am attaching the photos.

I also attach several of the files read from the same 29F400BT flash memory but all with different data.

Hmm...looks weird

Your Software/Firmware for this Programmer up to date?
Maybe you try different ICs in the section menu.....but look for AMD 29F400BT

Minipro (ori) reads fine that chips, but you must have a very good contact between eprom and adapter, no red dot when you test the chip....

Hi volker, I have tried with your csok flash file and the vehicle starts but gives ABS error so I need to modify its own flash.

I have read the flash memory four times in a row today and now it gives me the same data and that I think is correct. I had to press the memory with my finger over the adapter to make good contact.

Could you check the original file and the file modified by me with AETOOLS and then correct the checksum with WinOLS to tell me if I have done the job correctly?

Thank you very much.

HI, I have tried to do the work myself.

I have used the AETOOLS software to modify the flash and WinOLS to correct the checksum. The problem is that WinOLS shows me an error and I don't know if the job is done correctly.

Could someone tell me if I'm doing the right thing?

Attached screenshots of the programs.

Thank you.

HI, my work is not working . The car won't start.:shot:

Can anyone check the checksum of my modified file with AETOOLS ?.

Thank you.
