If error codes indicate a specific issue (e.g., faulty sensor, disconnected connector), perform repairs according to the manufacturer's service manual.
Reconnect any loose connectors and replace malfunctioning sensors or components as needed.

4. Clear Error Codes

With the OBD-II scanner still connected, navigate to the option to clear or erase error codes.
Follow the prompts on the scanner to clear the airbag warning light from the system.
Confirm that the scanner indicates successful code clearing.

5. Reconnect Battery

Reconnect the negative battery terminal securely.
Ensure all tools are removed from the engine bay and that the area is clear of debris.
