Airbag Peugeot 307 problem

Estimated:
I am new here and I would like
my Peugeot 307 I started with a computer problem that tells me an error in airbag or belts with pretensors
it sounds every so often and the light of the burning air
is taken to a mechanic and scan it with the Peugeot Planet 2000 and throws the sieontal error
of inflatable cushion. Local
and the mechanic is not clear where to attack the problem, prefers to be clear where it is the error not to disarm the whole self and not so expensive the arrangement
hopefully they can help me see where the error really is
really

The first thing is to erase the memory of the computer, there are enough that is enough.
