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 in this section are schematics reflecting communications networks installed to RHD vehicles only. For detailed layouts of the various communications networks installed to RHD and LHD vehicles refer to the electrical guide.

The communications networks available on the vehicle are shown below:

DIAGNOSTIC CONNECTOR

The Diagnostic Connector (J1962) is connected to the BCM/ GWM through the Diagnostic over Internet Protocol (DoIP) and the HS CAN diagnostic bus. The DoIP is the prime connection for the Jaguar Land Rover (JLR) approved diagnostic equipment.
