You must go to the workshop to read the failure memory of the switchboard since SRS has to do with the activation of the airbag and the pyrotechnic pretensioners of the seat belts.
That light will not turn off even if you disconnect the battery because it is a relevant failure, (sometimes the minor failures are erased if you leave the car with the battery disconnected)
a greeting and please do not possess two equal themes in the same thread because if I erase it, I eliminate the entire publication.
