System Description
SYSTEM DESCRIPTION
The body system on the Dakota (AN) and Dakota Quad Cab (AN84) consists of a combination of modules that communicate over the PCI bus
(Programmable Communication Interface multiplex system). Through the PCI bus, information about the operation of vehicle components and circuits
is relayed quickly to the appropriate module(s). All modules receive all the information transmitted on the bus even though a module may not require
all information to perform its function. It will only respond to messages "addressed" to it through a binary coding process. This method of data
transmission significantly reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. All of the information about the
functioning of all the systems is organized, controlled, and communicated by the PCI bus, which is described in the vehicle communication of this
general information.
