Lincoln Aviator: Module Communications Network / Description and Operation - Communications Network - Overview
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.
The information or messages that can be communicated on these wires
consists of commands, status or data. Multiplexing reduces the weight of
the vehicle by reducing the number of redundant components and
electrical wiring.
The vehicle has 2 module communication networks connected to the remote DLC, located under the instrument panel. The communication networks are:
The vehicle has 5 communication networks that do not communicate directly with the diagnostic scan tool. The GWM translates the messages on these 5 networks and transfers the signals to the DIAG 1 and DIAG 2 circuits at the remote DLC. Messages communicated on the HS-CAN1 are communicated to the DIAG 1 connection, all other networks are translated to the DIAG 2 connection at the remote DLC. The communication networks are:
-
HS-CAN1
-
HS-CAN2
-
HS-CAN3
-
HS-CAN4
-
MS-CAN

Removal
NOTICE:
Suspension fasteners are critical parts that affect the
performance of vital components and systems. Failure of these fasteners
may result in major service expense. Use the same or equivalent parts if
replacement is necessary. Do not use a replacement part of lesser
quality or substitute design...
