Airbag Witness Xara Picasso

Hello, I tell you the problem I have with my Xara Picasso. The airbag failure witness is lit when he wants and I have already reviewed all the connections except the switchboard. After seeing what is online about this car, I think it is cable failure more than anything else, although I only have to check the switchboard but I do not do it because I am afraid of the stick that you can put in the workshop. If anyone knows anything about it, I would be very grateful for any information. Thank you so much

Look at what I have understood, in the French vehicles that light is fixed when you disconnect the battery, that is, it is turned on, but what what you do is turn on and turn off when it occurs without a definite pattern, then if it can be cable or false contact problems

Have you reviewed the connections under the co -pilot seat? They usually fail a lot, the pretensioners of the belts are usually going.

It only remains to check the switchboard or a cable because it wants, not always, or following any specific order, but thanks for answering.
