Data Link Connector (DLC)

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