- 1). Locate the vehicle's OBD-II port on the driver's side dashboard near the fuse panel cover. The port should be the same size and shape as the connector end of your OBD-II reader. An OBD-II reader is a small, hand-held, computerized device that you can purchase from your local auto parts store.
- 2). Plug the reader into the port. Put the key into the ignition and turn it to the "II" position, but do not start the engine. Wait while the vehicle's electrical system powers on the OBD-II reader.
- 3). Find the "Delete Codes" command on the reader, or a similar command. Commands vary between readers, depending on its manufacturer. Select the command and wait for the "Command Sent" message to display or until the main menu reappears on the device.
- 4). Unplug the reader and start the vehicle's engine. Verify that all warning and service lights have shut off on the instrument cluster. The computer has been reset and the codes have cleared.
