Message center

OVERVIEW

The message center is a Liquid Crystal Display (LCD) located in a central position in the instrument cluster. The message
center displays system and vehicle status information to the driver.

• NOTE: Vehicles before 2010 MY: The message center is fitted to high line instrument clusters only.

• NOTE: Vehicles from 2010 MY: the message center is fitted as standard to all vehicles.

The instrument cluster receives message center data from the Central Junction Box (CJB) over the medium speed
Controller Area Network (CAN) bus. The CJB generates this data based on medium and high speed CAN bus inputs and
hardwired inputs received from various system control modules. Software contained within the instrument cluster converts
the data from the CJB into display messages for the driver.

DISPLAY MODES

The message center has 8 different display modes as shown in the table below.

Test images displayed to check LCD function

Display Mode 0

This mode is entered when the ignition is switched off and the CAN bus network is asleep. No characters or symbols are
displayed when in this mode. The mode is exited when either power mode 6 (ignition on) is active or the driver enters the
customer configuration 'Information' mode.

Display Mode 1

This mode is entered when power mode 6 is first active. The full screen message 'SYSTEM CHECK IN PROGRESS' is
displayed for approximately 3 seconds while the instrument cluster carries out an internal diagnostic routine. After the 3
second time period, display mode 2 will become active. If during the 3 second period the ignition is switched off, the
message center will revert back to display mode 0.

Display Mode 2

This is the normal operating mode of the message center and will automatically become active after display mode 1.

Display Mode 3

This mode is entered by pressing the trip computer button when the message center is in display mode 2. Trip computer
information will be displayed for 20 seconds after which time the display will revert back to display mode 2.

Display Mode 4

This mode is entered automatically if the message center receives warning or status messages from the CJB. The whole
screen is used to display warning/status messages, over writing the ambient air temperature (display mode 2) and trip
computer (display mode 3) information. Warning messages are displayed for 3 seconds, after which the display will return
to the previous display mode (2 or 3). Status messages do not extinguish until the status is rectified, for example screen
wash is added to the windshield washer bottle to remove the 'LOW WASHER FLUID' message. If more than 1 status
message is present, the screen will scroll through each message at 3 second intervals.

All current warning/status messages are scrolled through at 3 second intervals when the vehicle first enters power mode 6,
and when the ignition is switched off. These are displayed in order of priority, the most important message being
displayed first.

Display Mode 5

Display mode 5 is entered when Terrain Response is selected. This mode has 3 formats. Format 5A displays the same
information as display mode 3 with the addition of a Terrain Response icon in the top left hand (LH) corner of the screen,
and a steering wheel direction icon displayed centrally at the top of the screen.

Depending on the Terrain Response CAN message received from the CJB, the screen will enter either display mode 5B or
display mode 5C. W hen in display mode 5B the whole screen will be used to display Terrain Response messages, over
writing the information shown in mode 5A.

If the screen adopts display mode 5C the top third of the screen will display all Terrain Response option icons. The lower
two thirds of the screen will display Terrain response messages.

The instrument cluster provides a feedback signal to the Terrain Response control module informing it that the relevant
Terrain Response information is being displayed. The Terrain Response messages for all 3 display mode 5 formats can be
overwritten however if the message center receives a high priority warning/status message. If the message center is
unable to display Terrain Response messages due to this occurrence, the instrument cluster changes the feedback signal
to the control module from a value of 1 to a value of 0.

Display Mode 7

Display mode 7 is a diagnostic mode and can only be accessed using the Land Rover approved diagnostic system. The
diagnostic routine can be found in '413-00 Instrument Pack and Panel Illumination' under the 'Content Model' menu.

When in display mode 7, 4 different patterns are displayed to check that all areas of the LCD are functional.

MESSAGE PRIORITY

Messages are assigned priorities which are defined by the effect on driving safely and the functional ability of the vehicle.
New messages are displayed accompanied by a chime from the instrument cluster sounder. The messages are divided into
3 priority groups.

Priority Group 1
