problem with proxy aligment

[fokker2003]

Good morning.

I had a problem with a 2008 Fiat 500, 1.2 8V.
The car had a problem in the electrical installation and due to repeated short circuits the sw of the body computer was corrupted.
Bad checksum. The recalculation was made and the sw was repaired and after repairing the electrical fault everything started to work correctly, however the km blink.
It is not possible for me to do the proxy alignment because I always have a fault in the airbag node.
After much testing and research, I think I know the cause, and it is that the airbag node should be NAB, however I have NAB / ORC configured.
I have no way of changing it, could someone please help me?
I have a Multiecuscan Multiplexed license with a CANtieCar interface.

Thank you.

You could try unplugging the airbag ECU (disconnect battery first!) and then try the Proxi again.

However when you reconnect the airbag ECU (disconnect battery first!) you will have to do a Proxi again which may fail.

It is not possible for me to do the proxy alignment because I always have a fault in the airbag node.

can't see any airbag errors. post log from airbag unit. has it been replaced or is it original airbag ecu?

After much testing and research, I think I know the cause, and it is that the airbag node should be NAB, however I have NAB / ORC configured.

has nothing to do with your problem - NAB/ORC is just simple name MES uses for airbag node.

post your logs from "CAN Setup/Proxi" and "CAN Info" info tabs.

Sorry for the delay in replying, I had the car in the upholsterer this week. It is original and also I have tried with another unit with the same reference and I also have the problem, with both it does the same.
This is the log u mean?

Thank you very much for your help.

[fokker2003]

You could try unplugging the airbag ECU (disconnect battery first!) and then try the Proxi again.

However when you reconnect the airbag ECU (disconnect battery first!) you will have to do a Proxi again which may fail.

I have followed your instructions and I have not been able to do the alignment. With the unit disconnected for being absent from the node, with it connected again it gives me the same error as always.
I really appreciate your help, because without a doubt you know much more than I do, but I have to insist, the problem of the flashing km came from the correction of the body file.
The car got stuck and did not start, once the IDs of the keys were written again I managed to start it and later I realized that there were many errors in the programming of the body that I corrected with Multiecuscan.
Errors such as that a 1.3MJET engine was programmed, speed regulator, cornering light, etc.
I am quite clear that the cause of the sw in the bodysuit getting corrupted were the shorts that it had in the daytime lights, and I am surprised that it has not burned like many others I have seen.
I think the problem is that part of that corrupt file is relative to the airbag part because it is not possible that with 2 different airbag units it does the same to me. I have tried even another instrument cluster as well.
As I have already mentioned, I have looked for a lot of information on the net and I have seen many videos with Multiecuscan and in all those related to the Proxy they had NAB as airbag, not NAB / ORC.
I think there is a difference between both configurations.

Thanks again.

More info, this is what Autel Maxysys report after trying to Proxy allignement:

[shpuncik]

still can't see errors if there are any in airbag ECU.

what log file shows after you do proxi alignment - it should say why it failed on airbag ECU.

if someone made changes in body ECU while fixing it, you can always go to dealer and ask them to update it and restore proxi to original car configuration - could be fastest way to repair car.
