Disconnect the connectors and inspect for damage or debris.
Clean the connectors with electrical contact cleaner and reconnect them securely.

4. Replace Faulty Components

If any fault codes indicated a specific airbag module or sensor failure, replace those components as required.
Ensure all new components are compatible with the vehicle's model and year.

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Clear any stored error codes using the OBD-II scanner.
Start the vehicle and check if the airbag warning light remains off.
