Data Link Connector (DLC)

WARNING: This page is about a different car, the 2005 Pontiac Aztek and 2005 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The data link connector (DLC) is a 16-pin connector that provides the technician a means of accessing communication data for aid in the diagnosis. This connector allows the technician to use a scan tool in order to monitor the various parameters, and display the DTC information. The DLC is located inside of the drivers compartment, underneath the dash.
