Data Link Connector (DLC)

The data link connector (DLC) is a standardized 16-cavity connector. Connector design and location is dictated by an industry wide standard, and is required to provide the following:

• Scan tool power battery positive voltage at terminal 16
• Scan tool power ground at terminal 4
• Common signal ground at terminal 5
• Low speed GMLAN serial data bus at terminal 1
• High speed GMLAN serial data bus (+) at terminal 6
• High speed GMLAN serial data bus (-) at terminal 14
