Solution

1. Preparation

Gather tools: OBD-II scanner, ratchet set, gloves, and safety glasses.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle's OBD-II port, typically located under the dashboard near the driver's side.
Turn the ignition key to the "On" position without starting the engine.
Follow the scanner's instructions to read and clear any stored error codes.

3. Disconnect Battery

Use a ratchet set to loosen the bolt on the negative battery terminal.
Carefully remove the negative terminal and ensure it does not touch the battery post.
Wait for at least 15 minutes to allow all systems to reset.

4. Reconnect Battery

Reattach the negative battery terminal and tighten the bolt securely.
Ensure there is no corrosion on the battery terminals and that the connection is clean.

5. Verify Reset

Start the engine and let it idle for a few minutes.
Check that the check engine light has turned off.
If the light is still on, repeat the OBD-II scanner process to confirm codes are cleared.
