Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, oil filter wrench.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Check Oil Level

Remove the dipstick and wipe it clean.
Reinsert it fully, then remove it again to check the oil level.
If low, add the correct oil type as specified in the owner's manual.

3. Inspect Oil Filter

Use the oil filter wrench to remove the oil filter.
Check for rubber O-ring residue on the engine mount; clean if necessary.
Install a new oil filter, ensuring it is tightened according to specifications (usually hand-tight plus a quarter turn).

4. Inspect for Leaks

Reconnect the battery and start the engine.
Allow it to run for a few minutes while checking for leaks around the oil filter and drain plug.
Tighten the drain plug to the manufacturer's torque specifications (typically around 20-30 ft-lbs).

5. Reset Check Engine Light

Use the OBD-II scanner to clear any stored fault codes and reset the check engine light.
Test drive the vehicle to ensure the light does not reappear.
