Data Link Connector: Description and Operation

The Data Link Connector (DLC) is located at the lower edge of the instrument panel outboard of the steering column.

The Data Link Connector (DLC) is an industry-standard 16-way connector that permits the connection of a diagnostic scan tool to the Controller Area Network (CAN) for interfacing with, configuring, and retrieving Diagnostic Trouble Code (DTC) data from the electronic modules that reside on the data bus network of the vehicle.
