Airbag Renault Modus anomaly

Hello good I have a modus, with 50,000kms 1.2 16V, it turns out that the other day when the airbag witness was lit and the computer says that it has that anomaly, does anyone know any guideline to follow to check some defective connection? Or where to look before taking it to Renault, is only the failure with the result computer?
Thanks greetings

Look usually that anomaly appears by APARESER it is not advisable light.

Hello friend ,,,, I am new in this forum but I work in Renault.
That breakdown is quite common and is usually the cable of the intentors of the belts.
Have you moved the driver's seat lately ??? If so, it is usually because under the stalls of the seat the cable passes to the pretensioners of the belts and is usually damaged to move the seat. Check that the cable is not crushed by any ditio
