Durango 2WD V8-4.7L VIN N (2001)
Central Timer Module: Description and Operation
Sytem Description
The body system on the 2001 DN 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.
