2.3 Data Link Connector (DLC) Location
The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16pin connector
where diagnostic code readers interface with the vehicle’s onboard 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.
