DATA LINK REFERENCESDATA LINK REFERENCES
This table identifies which serial data link that a particular module uses for in-vehicle data transmission. Some modules may use more than one data link to communicate. Some modules may have multiple communication circuits passing through them without actively communicating on that data link. Additionally, these modules may utilize communication circuits not accessible from the data link connector (DLC), use the schematic reference link in the table for additional information. This table is used to assist in correcting a communication malfunction. For the description and operation of these serial data communication circuits refer to Data Link Communications Description and Operation
