Data Link Connector (DLC)

The data link connector (DLC) is a standardized 16-cavity connector. The DLC low speed serial data circuit is connected directly to the instrument panel (I/P) splice then to all other splices or modules. Connector design and location is dictated by an industry wide standard, and is required to provide the following:

• Pin 1 GMLAN low speed communications terminal
• Pin 4 scan tool power ground terminal
• Pin 5 common signal ground terminal
• Pin 6 high speed GMLAN serial data bus (+) terminal
• Pin 14 high speed GMLAN serial data bus (-) terminal
• Pin 16 scan tool power, battery positive voltage terminal
