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 connector.
Pinout
Below is the pinout of the Data Link Connector. The naming is taken from the Service Manual (SRT6).
