Description and Operation

Infotainment Control Module (ICM)


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTES:


If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new
module/component.


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with
an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into
account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Infotainment Control Module (ICM). For

System Operation BATTERY MONITORING SYSTEM - TD4 2.2L DIESEL VEHICLES ONLY
Periodically the battery monitoring system module will instigate a self-calibration routine. To self calibrate, the battery
monitoring system first charges the battery to its full condition.


NOTE: If the vehicle is only driven for short periods the charging process could take a number of days to complete.

Once the battery is fully charged, the battery monitoring system will discharge the battery to approximately 75% of its full
state of charge, but never lower than 12.2 V. The time taken to complete this part of the routine is dependent on the electrical
load on the vehicle.

When the second part of the routine has been successfully completed, the battery monitoring system will return the battery to
its optimum level of charge. The optimum level of charge will be between 12.6 V and 15 V, depending on battery condition,
temperature and loading.

The battery monitoring system module also monitors the battery condition with the engine switched off. If a low voltage
condition is detected the module can request the infotainment system is switched off to protect battery voltage. Once the
infotainment system has been switched off, the vehicle must be run for at least 5 minutes to charge the battery before the
infotainment system can be operated with the engine switched off.

BATTERY MONITORING SYSTEM - SINGLE AND DUAL BATTERY SYSTEM VEHICLES

When the ignition is off (power mode 0), the BMS control module records the primary battery state of charge and begins to
monitor the battery condition from this point.

If the battery state of charge falls by 7%, the BMS control module will monitor the primary battery for 5 minutes. If after the 5
minute monitoring period, the primary battery charge has continued to fall due to the quiescent drain current being too high,
the BMS control module will determine that some control modules are still 'awake'. The BMS control module sends a shutdown
message on the LIN (local interconnect network) bus to the GWM (Gateway Module). The GWM sends a CAN (controller area
network) bus message on both the medium and high speed networks to all control modules, requesting them to shutdown.

The BMS control module will monitor the primary battery state of charge for a further 5 minutes and determine if the primary
battery state of charge is still dropping. If a quiescent drain current continues, the primary battery state of charge will
continue to drop. If the state of charge falls to 12% of the initial monitoring value, the BMS control module determines that
one or more control modules are still awake and a failure to respond to the shutdown request may indicate an error state
within the control module(s).

BMS Low Battery Warning and Energy Management Messages

The BMS continuously monitors the condition of the primary vehicle battery. If excessive battery discharge occurs, the system
will begin to shut down non-essential electrical systems in order to protect the battery.

If the BMS calculates that battery condition is not within set parameters, there are 3 messages that can be displayed, 2 on the
touch screen and 1 on the message center. These inform the user that the battery is either at a low level of charge or the
engine-off power consumption limit has been exceeded.

Low Battery - Please switch engine on or system will shutdown in 3 minutes: is displayed as a Warning on the
touch screen if the engine is not running. This indicates that the battery has fallen below a predefined threshold. As
soon as the battery is charged back above this threshold then the message will be removed.
Low Battery - Please start your engine is displayed on the message center if the engine is not running. This indicates
that the battery has fallen below a predefined threshold. As soon as the battery is charged back above this threshold
then the message will be removed or it can be manually removed by pressing 'OK'.
System will shut down in 3 minutes: is displayed as an Energy management on the touch screen if the engine is not
running, and system features are causing excessive battery discharge. After 3 minutes the BMS will begin shutting
down vehicle systems. Normal system operation will resume when the engine is started.

This is based on a percentage of battery capacity available for the customer to use with the engine off. The percentage can
change based upon several factors.

Once triggered, the resetting of this message will not occur until the vehicle is driven for 10 minutes with the engine running
(to allow the battery to recoup any lost charge). However, if the engine is run for less than 10 minutes, the message will only
be displayed after an additional 5 minutes with the ignition on but engine off.

BMS Control Module Self Calibration

first charges the battery to its full condition.


NOTE: If the vehicle is only driven for short periods the charging process could take a number of days to complete.

When the second part of the routine has been successfully completed, the BMS control module will return the battery to its
optimum level of charge. The optimum level of charge will be between 12.6 V and 15 V, depending on battery condition,
temperature and loading.

The BMS control module also monitors the primary battery condition with the engine switched off. If a low voltage condition is
detected the BMS control module can request the infotainment system is switched off to protect battery voltage.

DUAL BATTERY SYSTEM - DUAL BATTERY SYSTEM VEHICLES ONLY

The dual battery system prevents electrical loads on the vehicle being subjected to low voltage levels during an ECO
(stop/start system) engine start. Low voltage can occur due to the power demand of the TSS (Tandem Solenoid Starter) motor
and could result in degraded performance of components and/or system control modules. The GWM contains the software to
control the dual battery system and electrical load management system to ensure that ECO engine starts do not affect other
vehicle systems.

The dual battery system isolates all power supply sensitive electrical components which may be affected by low voltage from
the primary battery due TSS motor operation, and supplies them with power from the secondary battery when an engine start
is in progress.

The DBJB (Dual Battery Junction Box) contains two contactors, which operate to change the power supply into two separate
circuits when an ECO engine start is required. Sensitive electrical components are supplied from the secondary battery. The
primary battery power is used exclusively to supply the TSS motor and maintain essential power loads to the engine
management system required for engine starting. The contactors are operated by the DBM (Dual Battery Module) on receipt of
LIN bus information from the GWM.

AUDIO SYSTEM OPERATION System Operation

The components of the audio/infotainment system are all connected on the MOST (media orientated systems transport) ring.
The MOST (media orientated systems transport) ring is a fibre optic communications bus for multimedia applications. Audio
and control information is passed around the MOST (media orientated systems transport) ring and can be picked up by any of
the systems units. For example, radio station tuning/selection input by the vehicle user into the Touch-screen is sent along the
MOST (media orientated systems transport) ring and collected by the IAM (integrated audio module) which then selects the
requested radio station.

MOST (media orientated systems transport) technology uses a plastic optical fibre which forms a network connecting the audio
and multimedia system components. Each component in the ring is connected to the plastic optical fibre through a device
known as a FOT (fibre optical transceiver). Each FOT (fibre optical transceiver) has two optical connections; one connection is
sensitive to light and is the input, the second connection forms the light source and is the output. The system operates by
connecting the output from one FOT (fibre optical transceiver) to the input of another FOT (fibre optical transceiver).
The light signals are sent in one direction only and are formed in the following way:
Electrical signals are converted into an electrical current
The current then drives an LED (light emitting diode) in the FOT (fibre optical transceiver) to produce a high intensity
red light
The LED transmits the light through a fibre optic cable A photo diode in the FOT (fibre optical transceiver) at the opposite end of the fibre optic cable detects the light.
The following components may be connected to the MOST ring dependant on the vehicle equipment level:
IAM (integrated audio module)
Touch-screen
ICM (information control module)
DAB (digital audio broadcasting) radio receiver (Optional - Europe only)
Satellite radio digital receiver (Optional - NAS only)
Power amplifier (Not fitted to the Jaguar Sound System)
Portable audio module (Optional)
Telephone control module (Optional)
Navigation computer (Optional)
TV tuner (Optional)


NOTE: Do not view the red light directly

MOST is a synchronous network. A timing master supplies the clock information and all other devices on the network
synchronize their operation to this clock. The timing master for the MOST (media orientated systems transport) network on this
vehicle is the ICM (information control module). This unit also controls and manages the MOST (media orientated systems
transport) ring and the system components.

An Optical Bus tester is used in conjunction with the Jaguar diagnostic system to diagnose the MOST (media orientated
systems transport) system. The Optical Bus tester emits a visible, high intensity red light which can be connected into the ring
at any point to test the ring integrity. Disconnecting a MOST (media orientated systems transport) connector will reveal if the
high intensity red light is visible.

If a break occurs in the MOST (media orientated systems transport) ring fault codes are stored in the ICM (information control
module) which can be retrieved using the Jaguar diagnostic system equipment.

With reference to the audio system information and signal transfer the instrument cluster is the gateway between the high
and medium speed CAN bus communication protocols. The ICM (information control module) is the gateway between medium speed CAN and the MOST (media orientated systems transport) 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 (information control module) gateway. The ICM (information control module) calculates the volume adjustment
required. The corrected audio volume level signal is sent on the MOST (media orientated systems transport) network to the
IAM (integrated audio module) 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.
