I was in an accident and the seatbelt pretensioners activated but my airbags did not deploy. When i got my vehicle inspected the shop noticed my airbag system needed to be replaced saying the airbag diagnostic module, right & left front air bag impact sensors needed to be replaced. The impact of my vehicle was very minor and could not have damaged the airbag diagnostic module internally. I do believe this was a preexisting issue and it has just now been noticed when my car had to be thoroughly inspected.
