Follow the scanner's instructions to clear the fault codes from the airbag control module.
After clearing, check for any messages confirming that the codes have been successfully erased.

4. Inspect and Reconnect Components (if necessary)

If any fault codes are related to specific components, inspect those components for damage or disconnection.
Reconnect any loose connectors, ensuring they are secure.
