Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery negative terminal for safety.

2. Check and Add Oil

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the correct type of oil (consult the owner's manual for specifications) until the level is within the acceptable range.

3. Inspect and Tighten Oil Filter

Locate the oil filter and inspect for any signs of oil leakage.
If the oil filter is loose, tighten it using the appropriate filter wrench to ensure a proper seal.
If damaged, replace the oil filter with a new one.

4. Inspect Drain Plug

Check the drain plug to ensure it is properly tightened.
If there is any oil leakage, remove the drain plug, replace the washer if necessary, and reinstall it securely.

5. Reset Engine Light

Reconnect the battery terminal.
Use the OBD-II scanner to clear any stored trouble codes related to the check engine light.
Start the engine and check if the light remains off.
