How do I connect the Code Reader to my vehicle and retrieve diagnostic trouble codes?

Turn the ignition off, locate the 16-pin Data Link Connector (DLC) under the dashboard, and connect the Code Reader cable — the connector is keyed and only fits one way. Once connected, turn the ignition ON (do not start the engine), and the Code Reader will automatically turn on, display 'rEAd,' and retrieve any stored codes within 10–60 seconds. If more than one code is present, press the SCROLL button to view additional codes. (Page 17)
