Data Link Connector (DLC)

The data link connector (DLC) is a multiple cavity connector, which provides the means to access serial data from the TCM to aid in powertrain diagnosis. The DLC allows the technician to use a scan tool to monitor various systems and display diagnostic trouble codes. The DLC connector is located with the driver compartment, directly below the steering column.
