Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, oil filter wrench, torque wrench, and oil catch pan.
Ensure the vehicle is on a flat surface and the engine is cool.

2. Scan for Error Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and note any error codes for further investigation.

3. Check Oil Level

Remove the dipstick, wipe it clean, and reinsert it fully.
Pull it out again to check the oil level. Ensure it is between the minimum and maximum marks.
If necessary, add the correct oil type as specified in the owner's manual.

4. Inspect Oil Filter and Drain Plug

Use an oil filter wrench to check the oil filter for proper installation.
Ensure it is tight and not leaking. If it is loose, tighten it to the manufacturer's specifications.
Inspect the drain plug for leaks; tighten if necessary and ensure it is at the correct torque specification (usually around 30 ft-lbs).

5. Reset Oil Change Reminder

Follow the owner's manual instructions to reset the oil change reminder light, typically done using the vehicle's instrument cluster controls.
