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. This table is used to
assist in correcting a communication malfunction. For the
description and operation of these serial data communication
circuits refer to .
