diagnostic code readers interface with the vehicle's on-board computer. The
DLC is usually located 12 inches from the center of the instrument panel (dash),
under or around the driver's side for most vehicles. If Data Link Connector is not
located under dashboard, a label should be there telling location. For some
Asian and European vehicles, the DLC is located behind the ashtray and the
ashtray must be removed to access the connector. If the DLC cannot be found,
refer to the vehicle's service manual for the location.
