Hi everyone, hope you're all doing well.

My Punto has developed a problem. Less than a week ago, the battery had gone flat due to me managing to leave the lights on. Since jumpstarting the car, a red airbag light has come up on the dash. A year ago I had an issue with both lights coming on and I managed to fix it with that wire Fiat produced for the issue. All was well until now. This light has prevented me from taking this car for an MOT. I've gotten it diagnosed and these are my codes. Car has not been in any accident and has not suffered any impacts. What do I check or replace?

Sidenote, The code would not clear. As we attempted to, it'd just return

Code

Due to low voltage, the airbag control unit that is located almost on the floor underneath the dashboard, registered the issue (as from being on an accident). The error is stored only on that unit (that communicates with ECU) and the usual tools does not allow you to delete the error. You can delete it and make it work again but I think you have to find someone who does that, knows how to do it and has the needed tools or you will have to get the tools yourself (I don't know witch they are exactly).
And you could try first to do a nice cleaning of the connectors of that unit using electrical contact spray. First disconnect the battery terminals and after that do the cleaning. It might work again after that.
