Turn the vehicle's ignition to the "On" position without starting the engine.
Follow the scanner prompts to retrieve and record any stored trouble codes.
Choose the option to clear or reset the codes in the scanner menu.
Confirm the action and wait for the scanner to indicate that the codes have been cleared.

3. Reconnect Battery

Reconnect the negative battery terminal securely.
Ensure all tools and equipment are removed from the engine bay.
