Initial Inspection and Diagnostic Overview

Data Link References




This table identifies which serial data link that a particular module uses for in-vehicle data transmission and communication with the scan tool. Some modules may use more than one data link to communicate. Some modules may use different circuits for functional and diagnostic communication. 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.
