Communications Network

OVERVIEW
A number of different types of communication network are incorporated into the vehicle wiring harnesses for the transmission of commands and information between control modules. The configuration installed on a particular vehicle depends on the model and equipment level.

NOTE:
The control diagrams shown later in this article are schematics reflecting communications networks fitted to LH (left-hand) vehicles only. For detailed layouts of the various communications networks fitted to LHD (left-hand drive) and RHD (right-hand drive) vehicles, refer to the Electrical Guide.
The communications networks available on the vehicle are shown in the table below.
