Overview 

Multiplexing is a method of sending 2 or more signals simultaneously over a single circuit. Multiplexing allows 2 or more electronic modules (nodes) to communicate over a twisted wire pair [data (+) and data (+)] network.

Multiplexing reduces the weight of the vehicle by reducing the number of redundant components and electrical wiring.
