Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Inspect Oil Level and Quality

Remove the dipstick, wipe it clean, and reinsert it to check the oil level.
If oil level is low, add the correct type of oil as specified in the owner's manual.

3. Check Oil Filter Installation

Raise the vehicle securely on jack stands if necessary.
Inspect the oil filter for proper installation; tighten or replace if it is loose or damaged.
Check for any oil leaks around the filter.

4. Verify Engine Oil Type

Confirm that the oil used meets the specifications outlined in the owner's manual (e.g., viscosity and API service classification).
If incorrect oil was used, drain the oil and replace it with the correct type.

5. Clear Error Codes

Reconnect the battery and use the OBD-II scanner to clear any stored error codes.
Start the engine to confirm that the check engine light does not reappear.
