Hello, I recently had a little front end collision and the airbags deployed. I have read that changing the srs unit will fix the crash data issue. I’ve changed that and checked the voltage on the yellow wire that goes to the seatbelt retractors as well as the airbag connector and still get the same reading of 4.5 volts on both. I’m not 100% on what the voltage is supposed to be but I’m pretty sure that 4.5 volts would deploy an airbag. This is the only thing left to having my car back and I’m stumped. My main question is, will the seat belts lock up with the 4.5 volts running to them as well as the airbag deploying? Any input is appreciated I’m new to the whole crashed car thing and srs system.

Anyone? I really need to know why I still have power to the airbag or am I supposed to have it at all times and the sensor is the main control for deploying the airbag?

If the bags deployed, you will need to replace:

2 airbags
both belt retractors
SRS control unit

Thanks for responding Billman. I have changed the srs module and have gotten seatbelts and airbag I’m just curious as to if the airbag is going to explode with the 4.5 volts that’s running through the connector to the airbag. If not, what is the voltage for? If you can’t answer because of safety reasons, I understand.

Thanks again.

Thanks for the response Mikey. That would make sense that it had to have a way for the srs light to come on and it might take a little long for the airbag to get the voltage to needs to explode so it’s already stored there. I have an aftermarket steering wheel so the light is already on or that would be the sure fire way to tell. I’ll test this. Thanks again for all the input.
