Big Problem C2 VTR Siemens SID 806

[Driver]

Hello to all. Unfortunately, today I had a big problem on this car. Days ago I read in boot mode, this ecu without any problem. Today I edited the correct file, the chk and written to the file by OBD. Since qu? all good writing ? come to a good end.

I try to do a start up, the car does start but does not start.



I also tried to rewrite the file ori from boot mode. The write is successful, but the machine doesn't want to leave. :mad:

I have read somewhere that these ecu rewrite the chk every time you turn the key, and if ? as I think at this point you should be disiallineate things.

[guidotacco]

try to do a partial scodifica

[Driver]

With that software I advice you to do it? :confused:

[guidotacco]

meucci!or is it that you resetto the rolling code

[guidotacco]

I forgot,mail the file read in boot ori from the flash 29f400

[cinqueturbo]

With that tool to work?
this is the same as here not only the driver for the file?
E-mail the file ori and mod..
especially the read file in the boot...

[Driver]

I read and written with Gall V53 is to boot from the OBD (Written) without any problem.



I tried to do the scodifica rolling code with the time but also cos? it does not go!

[jolidj]

according to me you should write to lori and try to do an alignment cn diagnosis dedicated.
if nn you can then calculate the possibility of that and the game when you've been given the boot.

[SandroMarciano]

I ? happened to me, to resolve this I have driven the citroen, where you probably have done some sort of update

Then the main problem and the cecksum..
why? even winols recognizes him..
according to me,
1), or try to write to the file Ori in the Boot
2), or find a file Ori with cecksum OK or try to calculate your files
3) or try to write it can be seen from the AM29F400, and writing with the programmer,
4) try with Lexia or contact Citroen..
5) request the assistance of the online service of the forum..

[cinqueturbo]

Write this file in the Boot and let me know..

[Driver]

Try to write the ori from the boot mode of the I have already? I tried it but no go.

When I wrote the mod file: 7439, the car, the less it was starting but didn't.

Then I rewrote his gold medals from the OBD and got to 100% and then the cock has written err_CHK impossible to verify (or something like that).

[Driver]

Write this file in the Boot and let me know..

Ok do it now and I'll give you an answer! Thank you all guys for the support!!! :)

[Driver]

[cinqueturbo]

You may have noticed that the file was a immo Rolling Code Reset
so it should be as I think.. the problem of cecksum..
now the ec has to make several attempts otherwise I don't know what to tell you..
try this other file..

[Driver]

Tried, but nothing... :(

Do quest another test then you really don't know how to help you maybe follow one of the suggestions above..

species s? you do not want to go in, Citroen, please contact the online service will definitely assist you to the best

[cinqueturbo]

I forgot connects to the ECU and then turn on in the picture for a few minutes and then re turn off for 3-4 minutes, and only now put in motion..
I hope you solve..

[Driver]

Tried but nothing to do. I appreciate your help thanks. I try to ask the assistance of the forum. :(

I did a test. I've written in the boot mode the file ori and then I reread it immediately after, and compared conil file golds that I had previously read when everything still worked, and they are different. Start the same then at a certain point one just written it all goes to zero almost at the end of the map. How ever this thing? I attach the 2 files to cos? you understand better...

The original (when it was working): https://www.professionalchiptuning.net/showthread.php?269-C2&p=85925&viewfull=1#post85925

Original Written and reread it in the Boot: 7443 :confused:

I'm at the point from tests made changes tool

yes, I also tried it with all the systems to eliminate rolling code, but none worked... The problem for you ? derived from the fact that you have rewritten a file that was not pi? what the machine was expecting... you were supposed to read the file again after the attempt to go in the bike failed and restore the original one... unfortunately the rolling code and each attempt to power-on checks the code when you start and change it according to an algorithm... if you do not find what you expect does not even turn the starter motor... in my rel? to pi? can't I just... at the end we did not give up, and I have sworn not to do ir? siemens for a long time...

[Driver]

Then, I did some more testing this evening before giving up altogether!!! They are stubborn!!! I have rewritten my gold and nothing to do. Then I recovered a file ori in the network with the same HW and SW, and guess what?? And' resurrected!!! I can't believe it...

Thanks to all for the help and for the patience. You can not imagine the satisfaction to feel the car starting. This is for me ? a passion\work and even if sometimes there are these moments no when all rifunziona ? really satisfying!!



However, be that as it may for a while I don't want any more? to see this Siemens...

you contrrollato the differences between the two files, to limit post that we look at them to see the problem where'.

[legendaryslave]

Very probably a wrong reading of the file ori initially

[SandroMarciano]

I am glad for you, even if in my case it did not work this attempt, which of course I had also done...

Comparing it with the one that you can? find at the beginning of this discussion, we see that they start the same and at a certain point the bed from me, it all goes to zero while this continues, there will be curves, and then return to be the same. Among other things, the part that is missing ? a part where there are maps important. This is also the reason I think that ecm is not I recognized the driver.

I rileggerei the map in the ecu, and if it is equal to what you have written will that and go ahead with the changes.

[sportknight]

however, this time, attentive to the rolling code...

since we wanted to know for the rolling code,but it also changes when we turn and turn the power during read/write into the boot when it asks you to turn off the power?

What I cheidevo me.

Excuse my ignorance, but if it has the rollincode, as he has to start again with a file ori that it was nice to read from this ecu and the code written to the last time it would not be correct for this?

escapes me something. :rolleyes:

[sportknight]

the mystery... :D

[sportknight]

no man can reveal to us the mystery of the rolling code?

[SandroMarciano]

from my experience covers both, the ecu+bsi, in fact, when it compromises the system recommended to mount the ecu set-bsi complete and coupled.
