Data Link Connector: Description and Operation

The Data Link Connector (DLC) (3) is a 16-way molded plastic connector insulator on a dedicated take out of the instrument panel wire harness. This connector is located at the lower edge of the instrument panel, outboard of the steering column. The connector insulator is retained by integral snap features within a rectangular cutout in the stamped metal lower instrument panel reinforcement (2), just below the lower edge of the instrument panel steering column opening cover (1).

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) data bus 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. The DLC on SRT10 models also includes a Programmable Communications Interface (PCI or J1850) bus link for diagnosis of the GateWay Module and a Serial Communications Interface (SCI) bus link for diagnosis of the Powertrain Control Module (PCM).
