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.
