In my 06 f150, my airbag light is on, pulling code 33, which is a driver side seat belt pretensioner fault. I could use a little help locating the module, and if anyone has dealt with this before, what should i look for and test? The truck was in a front end accident, and im assuming i will have to replace the module? Correct me if im wrong but doesn't it detonate and lock the seatbelt in an accident?
