Circuit Description
WARNING: This page is about a different car, the 2004 Saturn L300. However, it is still accessible from the selected car via links, so may be relevant.
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.
The scan tool will power up with the ignition OFF.
