Airbag Xantia witness

Hello, in my Xantia 2.0 HDI, I have been on the witness of The Airbag for some time, they have told me that it is a cable that goes below my seat, that is true and if it is how it can be solved, thanks and greetings

Good compa, the fact of having the light of the burning airbag indicates that one or more components of it do not work properly, in general and if you have not had any accident, it is because the serpentine located behind the direction steering wheel (not under the seat) has been cut off, it is screwed in a small plastic box just between the steering wheel itself and the light switches, directions and others.

Forgive for so long, thanks for the clarification, they had told me another movie, watch what I can do, thanks and greetings .....

Hello.
In many cars the problem that the airbag light is turned on, it is because the driver's seat or companion is moved and the connection under the seat moves causing more resistance that makes the fault light turn on.
The solution is always the same to go to the workshop to diagnose with the computer and delete the fault code.
I have come to remove the plastic connection and weld the cables but in extreme cases, it is best not to move the seats running.
Luck.....

Thank you, but I don't know what to do, because one says that in the steering wheel and another that under the seat, I think I will let it go to see if they clarify it, greetings
