Solution

1. Preparation

Gather necessary tools: OBD-II scanner, vehicle owner's manual.
Ensure the vehicle is parked on a flat surface with the engine off.

2. Connect OBD-II Scanner

Locate the OBD-II port beneath the dashboard on the driver's side.
Plug the OBD-II scanner into the port securely.

3. Turn On Ignition

Turn the vehicle's ignition to the "ON" position without starting the engine.
This powers the scanner and allows communication with the vehicle's computer.

4. Read and Clear Codes

Follow the on-screen prompts on the OBD-II scanner to read any stored codes.
After reviewing the codes, select the option to clear the codes and reset the check engine light.
Confirm the action when prompted by the scanner.

5. Disconnect Scanner

Once the codes are cleared, safely unplug the OBD-II scanner from the port.
Ensure the scanner is stored properly for future use.

6. Test Drive

Start the vehicle and take it for a short drive to ensure the check engine light does not re-illuminate.
