Your airbag module is connected to your airbags, sensors, and seatbelts. You may take it to a mechanic so they can scan your module for codes, and those codes will let you know what needs to be repaired.
If the module only has crash history from the accident, you can send it to us, and we can reset it. Unfortunately, we are unable to repair these modules, so if you have lost communication or have an internal failure code, that module will need to be replaced.
Additionally, I am not certain if these modules are compatible with different model years, as they usually have a VIN number attached. If the part number is the same, it might work, but it will require additional programming from your local dealer.
