The dual battery system comprises the following components:
Dual Battery Module (DBM).
Dual Battery Junction Box (DBJB).
Gateway Module (GWM).
Primary battery.
Secondary battery.

The GWM hosts most of the software required to control the dual battery system and components. The GWM monitors the
components and can store fault related DTC's.

The GWM also controls the charging system software in conjunction with the ECM, RJB, CJB and ABS (anti-lock brake system) control module via the high speed and medium speed CAN (controller area network) bus. The GWM software will monitor the
status of the stop/start system and determine when a stop/start event can occur. It can also intervene to maintain vehicle
systems by keeping the engine running or initiating a restart due to, for example, climate control system requirements or
request for restart from the ECM. A brake pressure signal is received from the ABS control module which will indicate to the
GWM that an engine restart is required from driver operation of the foot brake.

The GWM contains the intelligent power management system and the BMS software. Monitoring of the primary battery
condition for stop/start is controlled by the GWM and the BMS control module.

systems.

A typical example of information transfer is vehicle speed information from the ABS (anti-lock brake system) module used to
control the automatic volume control function. The vehicle speed information from the ABS module is sent on the high speed
CAN network and collected by the instrument panel gateway. The signal is passed to the medium speed CAN network and onto the ICM gateway. The ICM calculates the volume adjustment required. The corrected audio volume level signal is sent on the
MOST network to the IAM or Power amplifier (dependant on vehicle equipment level) for output to the speaker system.

AUDIO SYSTEM USER CONTROLS

Touch-Screen



Item Description 1 Touch-screen 2 Home menu button 3 Touch-screen on/off button The Touch-screen forms the basis of the audio system. It communicates with the rest of the audio/infotainment system on the
MOST ring and allows control of the audio system and other infotainment systems from a single point.

The Touch-screen communicates with the IAM on the MOST ring and provides the primary user interface and display of the
audio system controls. No configuration procedure is required if the touch-screen is replaced.

Calibration of the Touch-screen using the Jaguar approved diagnostic equipment enables updates to be downloaded as new
technology becomes available or any fault concerns require software updates.
The touch-screen provides user control of the following systems:

System Functions Audio Radio display AM/FM or DAB, auxiliary and portable audio, digital TV or CD (compact disc) Climate
control Air conditioning, distribution, seats, heated steering wheel, automatic air recirculation Telephone Digit dialer, phone book, last ten calls (made, received, missed) Navigation Destination, stored locations, navigation setup, route options Vehicle
Security, parking, valet mode, trip computer, clock, brightness, contrast, system settings, vehicle settings, display settings

7 Triple TV antenna module 8 RF filter The diversity antenna module, located on the left hand side of the heated rear window, receives signals from four antennas
located in the heated rear window, where one antenna is dedicated as an AM antenna.

The diversity tuning system ensures that the strongest signals are used by the radio system to ensure the best possible FM
reception. Using the three remaining receiving antennas serves to eliminate multipath signal distortion. Typically, the signal
from the antenna with the least noise is chosen, and the other antennas are ignored.

The diversity antenna module is an interface between the antenna aerials in the heated rear window and audio system
modules/tuners. It provides antenna signals to the AM/FM tuner in the IAM, to the DAB receiver and to the VICS (vehicle
information and communication systems) or TMC (traffic message channel) in the navigation computer.

There are three different types of diversity antenna module fitted depending on the vehicle market and infotainment
equipment specification:
AM/FM with one co-axial output
AM/FM and VICS/TMC with two co-axial outputs
AM/FM, VICS/TMC and DAB band III with three co-axial outputs
The diversity antenna module receives a power supply from the IAM.

Vehicle or other component generated electromagnetic interference may cause unwanted disturbances in the radio and TV
reception signals. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the
circuit. It frequently affects the reception of AM radio in urban areas and can also affect FM radio and television reception,
although to a lesser extent.

The RF filters, which act as RF isolators, are located on both sides of the heated rear window and are used to reduce the
electromagnetic interference. The left hand side RF filter is connected across the heated rear window power supply and used to
separate the DC (direct current) interference from the RF signals. The right hand side RF filter is used in conjunction with the
TV antenna module (if fitted). If the TV system is not fitted the filter is linked directly to ground.

INFORMATION CONTROL MODULE



The ICM is located beneath the IAM in the center console. The unit performs a range of infotainment and some climate-control
functions.

The ICM, which is the timing master of the MOST system; supplies clock information to all other devices on the network which
synchronize their operation to this clock.

The unit also controls and manages the MOST ring and provides the allocations of channels, system power management,
functionality and co-ordination of the other system components.

The system becomes operational when the vehicle is unlocked and a 'wake up' signal is received by the ICM on the medium
speed CAN. The ICM 'wakes up' all the control modules on the MOST system ready for immediate operation by the vehicle user. If the ICM is replaced it must be configured as a new module using the Jaguar approved diagnostic equipment.

Calibration of the ICM using the Jaguar approved diagnostic equipment enables updates to be downloaded as new technology
becomes available or any fault concerns require software updates.
