Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery for safety.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Retrieve and Diagnose Codes

Use an OBD-II scanner to retrieve trouble codes.
Note the codes and consult the service manual for specific diagnostic procedures related to the codes.

3. Address Identified Issues

If the codes indicate a specific issue (e.g., faulty sensor, low fluid levels), proceed with the appropriate repair.
- For sensor replacement:
  - Remove the faulty sensor using the appropriate socket.
  - Install the new sensor, ensuring it is properly seated and secured.
- For fluid top-offs:
  - Locate the fluid reservoir (e.g., coolant, brake fluid).
  - Add the recommended fluid type to the appropriate level.

4. Clear Codes and Test

After repairs, use the OBD-II scanner to clear the trouble codes.
Reconnect the battery terminal and start the engine.
Check if the dashboard warning light remains illuminated.

5. Final Inspection

Conduct a road test to ensure the vehicle operates normally.
Monitor for any reappearance of warning lights.
