Ensure the vehicle is parked on a level surface with the engine off.
Keep the keys in the ignition or within range of the vehicle, as some scanners may require it.

Locate the OBD-II port, typically found under the dashboard near the driver's seat.
Connect the OBD-II scanner to the port securely.

Turn the ignition key to the "On" position without starting the engine, or press the start button once without pressing the brake pedal (if equipped).

Follow the scanner's instructions to navigate to the "Read Codes" or "Diagnostic" menu.
Select the option to clear or reset codes, often labeled as "Erase Codes" or "Clear DTCs."

5. Confirm Code Reset

Confirm the reset process when prompted by the scanner.
Wait for the scanner to indicate that the codes have been successfully cleared.

Safely unplug the OBD-II scanner from the port.
Turn off the ignition.
