Communications Network: Overview
WARNING: This page is about a different car, the 2015 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
Multiplexing is a method of sending 2 or more signals simultaneously on the same network circuits. Multiplexing is used to allow 2 or more electronic modules (nodes) to communicate simultaneously over a twisted-wire pair [data (+) and data (-)] network. The information or messages that can be communicated on these wires consists of commands, status or data. The advantage of using multiplexing is to reduce the weight of the vehicle by reducing the number of redundant components and electrical wiring.
The vehicle has 3 module communication networks which are connected to the Data Link Connector (DLC), located under the instrument panel:
- High Speed Controller Area Network (HS-CAN)
- Medium Speed Controller Area Network (MS-CAN)
- Infotainment Controller Area Network (I-CAN)
