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 DLCs are required to provide a power supply, hot at all times, to Pin 16. This circuit 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.
