Solution

1. Preparation

Gather all necessary tools: OBD-II scanner, socket set, and a small flat-head screwdriver.
Ensure the vehicle is parked on a level surface with the engine turned off.
Disconnect the battery (negative terminal) if proceeding with that method.

2. Using an OBD-II Scanner

Locate the OBD-II port under the dashboard near the steering column.
Connect the OBD-II scanner to the port and turn on the vehicle's ignition (do not start the engine).
Follow the scanner's instructions to navigate to the "Clear Codes" or "Reset" function.
Confirm the action and wait for the scanner to reset the warning lights.

3. Resetting via Battery Disconnect (if applicable)

Ensure the ignition is off and all electronic accessories are turned off.
Use a socket set to loosen the bolt on the negative battery terminal.
Remove the negative cable from the battery terminal and leave it disconnected for at least 10 minutes.
Reconnect the negative cable and tighten the bolt securely.
Start the vehicle and check if the warning lights have reset.
