Solution

1. Preparation

Tools Required: OBD-II scanner, vehicle owner's manual (for reference).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Connect the OBD-II Scanner

Locate the OBD-II port under the dashboard, typically near the driver's side.
Plug the OBD-II scanner into the port.

3. Turn on the Ignition

Turn the vehicle's ignition to the "ON" position without starting the engine.
This allows the scanner to communicate with the vehicle's ECU.

4. Access Diagnostic Codes

Follow the specific instructions on the OBD-II scanner to retrieve any stored DTCs.
Review the codes and note any issues that need addressing.

5. Clear the Codes

Select the option to clear or erase the diagnostic trouble codes on the scanner.
Confirm the action when prompted.
Wait for the scanner to indicate that the codes have been cleared successfully.

6. Disconnect the Scanner

Once the codes are cleared, safely disconnect the OBD-II scanner from the port.

7. Test Drive

Start the vehicle and take it for a short drive to ensure the check engine light remains off.
