Airbag plug Nissan Micra K 12

Hello together! Since I have solved the problem with the control chain without great difficulties, I now have a new problem, and the airbag light flashes. As I have already read here in the forum, it is probably the brown Renault plug under the seat. I have already disconnected the battery, the connection disconnected, contact spray etc, again, and was nothing, will probably be a cable break. Now my question. Can the plug (after killing the electrics of course) out tr How does the error memory look, has to be deleted, or does the control search go out like this? For your help I would be grateful. Greetings to all!!!
