You will not be able to perform this repair without a scan-tool that can communicate with the Air-Bag system. This tool allows the mechanic to look and test affected components. It also allows the system to be reset, after the necessary repairs are completed. The Air-Bag deployed because the Air-Bag Control Module detected an impact. If you replace the air-bag before any necessary repairs are completed and before the system is reset, the new air-bag will deploy as soon as it receives power.
