Hello all,
kindly I need your help I have made a bit of a mess....

EDC16 0 218 012 961 Chroma 120cv

After unsoldered-bed-written-welded to the eeprom 95640 the car does not start and the diagnosis has the following errors:
P0641
P0651

I doubt that the file loaded in the eprom is corrupted since vlc does not recognize it.... someone can? check?
Do you have any suggestions/test you want to run?

Thanks

why? you've done this?

reload the original file...
and check the welds and the positioning even before...

I was trying on some equipment (digiprog and carprog) as readers of the eeprom.... and unfortunately the one that I have attached ? the file "original" (the first bed can be seen).

I redid the whole not changing the file, and unfortunately not ? changed nothing...

Can I try another dump?

you have to find the same ecu with HW and SW, if you have not broken the eeprom and/or welded evil or read bad..

I don't think is welded evil even why? from diagnosis, the ECU can't read the parameters (such as KM, etc) that are contained in the eeprom... the only errors present are P0641 and P0651.

I think that you have misread the eeprom... I can load the dump another Eprom of an ecu the same? Do you have any dump that I can try?

C'? someone on the area of province of Naples, or that I can? help?

anke wanting to help you can not download the file, you must have prior permission from the superiors

Or a full Backup...
what part are you from?

Are in the province of Naples,
I confirm hw 0281012961 and sw 1037386777

Unfortunately, for now I don't have a BDM interface... I only have the programmer eeprom...

0281012961-1037386777 is missing a piece

unfortunately I can not see the attachments.... that means missing a piece?
the file of the eeprom is not ? complete?

Thanks to all

Or realized that you are the province of naples, but where are you exactly?
maybe you're two steps away from me,
while one takes a coffee? we put in place is the ECU...

during the reading has jumped some strinhe will find another reading

I don't understand mil which is why one of them starts to unsolder, sladare and combine sti casini when you just need a bdm, also situated by the chinese in the middle of the road now...

Unfortunately I am a novice in this field:(
For this type of ecu ? just a BDM100 V1255?

Thanks to all for the help you are providing me.

Anyway, when that type of error means that you did not correct the cks in the file you uploaded.
Studying a bit the kind of errors do not are convinced that it is a problem of chk or wrong file, but I'm convinced that this is hw failure of the ecu.

The errors P0641 and P0651 are errors power sensors 1 and 2.... (the power supply that generates the ecu if I understood well).
I think that if I had the cks wrong I had to have P0601-internal memory checksum error...

What do you say ? correct this theory??

I'm wrong or I BDM100 or Rooster reads and writes only 4KB and carprog and conpani 8KB?

I read that some files need to be cut to be used with different interfaces (as read in from the serial port and write to the bank).
On the forum there are several posts on the subject, or am I wrong?

But in the case one to your problem of corrupted file thing cuts?
how to write a partial file with the cut side and still remains the part corrupted before?
and while peering or seen that the soft immo on these EDC16C39 are not very clear on partial on the e2prom in my possession..

to him, you need a good read of the ecu of the e2p after that with the programmer bdm or any instrument rivergina, and sets in motion both the file of the cmd does not ? other than the file that is read by a programmer or doubled

Ok grabbed,
merely come to doubt because of the difference of magnitude,
then comparing my 4KB and his 8KB I realized that his 4KB everything to ff or 00 now I can't remember..
another doubt comes to me with that SW can you? do a partial?
tai my non c'? partial, but only the total, and adiri tura on the flash?...
