Module Configuration

Principles of Operation

All configurable modules are packaged in a kit which
contains a warning label and a multi-language sheet re-
emphasizing the requirements to configure replacement
modules.
Replacement configurable modules must be configured
using WDS.
Market Configuration
This data is required so that modules can interact with the
vehicle correctly. By using WDS this data will be retrieved in
the following ways:
• Indirectly from a mirrored image of the old modules data
stored in an 'As is' database on DCS
• Indirectly from information stored in WDS
Configuration
The complexity of the electronics involved with module
configuration and the multiplex communication network
which they are connected to preclude the use of general
workshop electrical test equipment.
WDS contains detailed instructions on module
configuration.
Install the new module(s) and download the 'As is' data
using the vehicle configuration software on WDS.
WDS will permanently retain the configuration information

Customer Configuration
There are certain modules / functions that the customer may
or may not want reconfigured or enabled. Some of these
preferences are accessed through the 'in-car' menus,
available on the infotainment centre. Others are set in the
vehicle configuration or specific software files, these items
can be toggled or configured by WDS.
The 'As is' database (AML) holds customer original
preferences. When a new module is installed to a previously
upgraded or reconfigured vehicle these preferences can
retrieved and re-applied as required through WDS
Data Buses
The primary data required for control and operation is
carried on CAN data buses.
Two Can buses are used:
• High Speed CAN bus operates at 500 k bits / sec and is
primarily used to transmit powertrain data
• The Powertrain (high speed) CAN bus operates at 500 k
bits / sec and is only used to link the two PCMs
• Low Speed CAN bus operates at 125 k bits / sec and is
used to transmit data relevant to the body system.
Network Bus

MOST

The MOST network bus is a fibre optical network used only
for the Infotainment System
