Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a level surface and the engine is off before beginning any work.

2. Retrieve and Analyze Diagnostic Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's prompts to retrieve error codes.
Document the codes for further analysis.

3. Address Identified Issues

For engine-related codes:
- Inspect the indicated component (e.g., oxygen sensor, mass airflow sensor).
- Replace faulty components as necessary, following the specific repair procedures in the service manual.
For fluid-related warnings:
- Top off or replace fluids as necessary.
- Check for leaks or damage in hoses and connections.

4. Reset Warning Light

After addressing the issues:
- Reconnect the OBD-II scanner.
- Use the scanner to clear the diagnostic trouble codes (DTCs).
Turn off the ignition and then restart the engine to verify if the warning light remains off.
