Plug the OBD-II scanner into the vehicle's OBD-II port, usually located under the dashboard near the driver's seat.
Turn the ignition to the "On" position without starting the engine.
Follow the scanner’s instructions to read and record any trouble codes.

Using the OBD-II scanner, navigate to the option to clear or erase codes.
Confirm the action, and wait for the scanner to indicate the codes have been cleared.

Using the appropriate socket or wrench, loosen and remove the negative battery terminal (black cable).
Wait for 15-30 minutes to allow the vehicle’s systems to reset.

5. Reconnect Battery Terminal

Reattach the negative battery terminal and tighten it securely.
Ensure that there is no corrosion on the terminal before reattaching.
