Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, oil filter wrench, rags.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to reset the engine control unit (ECU).

2. Inspect and Correct Oil Level

Remove the dipstick, wipe it clean, and reinsert it to check oil level.
If oil is low, top up with the recommended oil type for the Genesis G70 (check owner's manual).
If overfilled, carefully siphon excess oil if necessary.

3. Check Oil Filter Installation

Use an oil filter wrench to ensure the oil filter is properly tightened (usually hand-tight plus a quarter turn).
If necessary, replace the oil filter with a new one, ensuring the old gasket is removed.

4. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any fault codes that may have triggered the check engine light.
Monitor if the light returns after clearing.

5. Test Drive

Take the vehicle for a short drive to allow the engine to warm up and monitor performance.
Observe if the check engine light reappears during the drive.
