Data Link Connector: Description and Operation
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 DLC's are required to provide a B+ at all times to Pin 16. This positive supply is used to power the scan tool. All DLC's 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.
