Solution

1. Preparation

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

2. Check Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert the dipstick and check the oil level; add oil if necessary.
If oil appears dirty or contaminated, drain and replace the oil with the correct type (e.g., 5W-30 synthetic) and refill.

3. Inspect Oil Filter

Locate the oil filter and ensure it is properly tightened.
If it is leaking, remove the oil filter using an oil filter wrench.
Apply a small amount of oil to the rubber gasket of the new filter before installation.
Install the new oil filter and tighten it to the manufacturer's specifications (usually hand-tight plus a quarter turn).

4. Reconnect Electrical Components

Inspect all electrical connections in the engine bay that may have been disturbed.
Reconnect any loose connectors and ensure they are secure.

5. Clear Error Codes

Use the OBD-II scanner to clear any error codes that may have been logged.
Reconnect the battery terminal and ensure it is secure.
