The Data Link Connector is the connector that you use to read the Diagnostic Trouble Codes (DTCs) from the car, using a tester such as Bosch ESI[tronic], Mercedes Benz StarDiag, or DRB III. Its plug is the same as an OBD2 / J1962 connector.
Pinout
Below is the pinout of the Data Link Connector. The naming is taken from the Service Manual (SRT6).
