Data Link Communications Operation

CLASS 2 SERIAL DATA LINK
The Class 2 serial data link allows the following modules to communicate data with each other:
^ The body control module (BCM)
^ The electronic brake control module (EBCM)
^ The inflatable restraint sensing and diagnostic module (SDM)
^ The instrument panel cluster
^ The powertrain control module (PCM)

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 is located at the DLC connector.
