Class 2 Serial Data Link

The Class 2 serial data link circuit is connected to certain modules on the vehicle. This circuit is used so the modules that are connected to it can share data with each other when needed. In addition, the Class 2 serial data link allows a scan tool to communicate with the modules for diagnostic and testing purposes.
The Class 2 serial data link, for the scan tool, is located at the DLC connector.
