- If damaged wiring is found, repair or replace the affected sections.
- Ensure all connectors are tightly secured and free of corrosion.

3. Replace Faulty Components

Sub-steps:
- If error codes indicate a specific faulty component (e.g., airbag module or sensor), locate the component as per the service manual.
- Disconnect the electrical connectors and remove the component (tools: socket set, screwdrivers).
- Install the new component, ensuring all connections are secure.
- Reinstall any covers or panels removed during the process.

4. Reconnect Battery and Clear Codes

Sub-steps:
- Reconnect the negative battery terminal.
- Use an OBD-II scanner to clear any stored airbag codes.
- Start the vehicle and check if the airbag light turns off.
