Clear the codes and observe if they return after a test drive.

3. Inspect and Replace Components

Gas Cap Inspection:
- Check for cracks or damage.
- Replace if necessary (use OEM parts for best results).
Battery Inspection:
- Examine battery terminals for corrosion.
- Clean terminals and ensure tight connections; replace the battery if health is poor.
Hybrid System Components:
- Visually inspect wiring and connections in the hybrid system for wear or damage.
- If error codes indicate a specific component failure (e.g., inverter), follow manufacturer guidelines for replacement.

4. Reconnect Battery and Test

Reconnect the negative battery terminal and ensure it is secure.
Start the vehicle and monitor for the check engine light.

5. Final Verification
