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.
