Lincoln Aviator: Electrical Distribution / Module Communications Network
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...

Disconnect
NOTE:
When the battery is disconnected and connected, some
abnormal drive symptoms may occur while the vehicle relearns its
adaptive strategy. The vehicle may need to be driven to allow the PCM to relearn the adaptive strategy values.
NOTE:
When disconnecting the battery to interrupt power to the
vehicle electrical system, disconnect the battery ground cable(s)...
