Fiat 500 Exchange faulty Airbag ECU

[MeierKurt]

Hello,

I have a Fiat 500 with a faulty Airbag ECU (ATIC99 burned). Partnumber 51963734

Unfortunately only used units are available as replacement.

My question is now are there Data, Coding String, etc. which need to be transferred from the old the replacement unit?
Or just proxi alignment and that´s it ?

B.R.

usually proxi is enough

Have done this with Punto Evo (2011), proxy allignment was enough.
