Data Link Connector (DLC)

The DLC is a standardized 16 way connector located below the instrument panel and close to the steering column, both the connector design and location are dictated by industry wide agreements. All DLCs are required to provide a power supply, B+ at all times, to Pin 16. This positive supply is used to power the scan tool. All DLCs supply a power ground at Pin 4 and a clean signal ground at Pin 5. The Class 2 serial data circuit is provided at pin 2 of the DLC.
