2.3 Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16-
pin connector where 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.
