Initial Inspection and Diagnostic Overview

Data Link References

This table identifies which serial data link that a particular control module uses for in-vehicle data transmission. Some control modules may use more than one data link to communicate. Some control modules may have multiple communication circuits passing through them without actively communicating on that data link. This table is used to assist in correcting a communication malfunction. Not all control modules listed will be applicable to all vehicles. Refer to the schematics to determine which control modules apply. For the description and operation of these serial data communication circuits refer to Data Link Communications Description and Operation Description and Operation.
