I was in a minor accident. Steering Wheel Airbag deployed and drivers seat belt locked. I followed instructions and removed SRS module. After I removed the primary bolt holding the seat belt (the other end of the belt connected to the pretensioner), the seat belt retracted. I put the bolt back in and the seat belt appears to work just fine now. Do I need to get it repaired, or just the SRS module?
You need to get it repaired.
we would scan the car to see which parts need to be serviced, without using a scan tool it reminds me of throwing darts at a dart board
Step 2 / if airbag lights still on gets seatbelt serviced
Yes, the seat belt still needs to be rebuilt because the internal pyro sensor is bad and will keep the airbag light on. You will need to send both parts, top seat belt pretensioner and the bottom anchor tensioner.
