Big Problem C2 VTR Siemens SID 806

[ugoboss]

Sorry for the absence, however, the car ? divided after writing this file ori via OBD: Annex 7485

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.

My question now ?: by modifying this file, and riscrivendolo the machine partir? or not? I'm tempted to try...

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.

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?

it escapes me something.

the mystery...

[sportknight]

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

[Macchinista]

According to me you should understand how it works exactly this cover of the rolling code. If ? a thing that concerns only the ecu, or includes, for example, the control unit of the body computer.

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.

I also think I am cos?. I also think that writing the ecu via the obd automatically at the end of writing the bsi or ecu recalculates all of the codes that serve them. So true that, when I wrote the file corroto via obd arrived at the end of the writing gave an error like: "chk error" or something similar, as if the writing via boot mode writes all without errors, but the machine would not start equally in none of the two cases. By writing the correct file instead of via the obd at the end of the writing did not give any error and you ? heard the wake up of the whole system.
