Information display (Discovery 3)

The information display is a liquid crystal display (LCD display), located at the bottom right of the instrument panel. The visible area of the LCD is 43x20mm and is divided into seven segments. When the information display is on, its illumination works as follows:

• When the trip odometer reset button is pressed, the odometer is illuminated and the odometer and trip odometer readings are displayed for 20 seconds
• When the ignition is turned on, the odometer turns on in the display mode of all functions

When the ignition is on and the lighting is off, the information display, controlled by the ambient light sensor, is fully illuminated with normal brightness. When the lighting is on, the display dims to a level determined by the pulse-width dimmer built into the light switch.

The data displayed on the information display enters the instrument panel from the control modules of other subsystems in the form of messages via the CAN bus. Odometer and trip odometer data comes from the ABS module, transmission data comes from the transmission control module (for models with automatic transmission) or from transfer case control module (for models with manual transmission).

Odometer

The odometer displays the total distance traveled by the vehicle, which is calculated by the instrument cluster microprocessor based on wheel speed data from the ABS module.

The 6-digit odometer display can display values up to 999,999 miles or kilometers. With the ignition off, the odometer reading can be displayed by pressing the odometer reset button. Readings are displayed for a short period of time.


The total distance traveled is recorded in an electrically erasable programmable read only memory (EEPROM) and working memory (RAM) instrument panel. This ensures that the total distance traveled is saved when the battery is disconnected. The distance is read and stored in the memory every 2 kilometers or miles travelled.

Trip odometer

The trip odometer displays the distance traveled since the odometer was last reset. The meter display is four digits and the fourth character representing 1/10 of a mile or kilometer is separated by a decimal point. The meter can display values up to 999.9 miles or kilometers. If this value is exceeded, the display starts at 000.0 miles or kilometers.

The counter is reset by holding the trip counter reset button on the instrument panel pressed for two seconds. Trip mileage is written to RAM but not written to EEPROM, so when the battery is disconnected, this data is lost, and when the battery is connected, the counter is set to 000.0.

Gear display

Automatic transmission

The gear display is designed to show the current position of the gear selector in models with an automatic transmission. During normal operation, the display shows the following symbols: P - park, R - reverse, N - neutral and D - drive.

If the transmission is in CommandShift™ mode, the display will also show the manually selected gear: 1, 2, 3, 4, 5, or 6.

The gear selector position display may also show information about automatic transmission malfunctions. The following letters are displayed to notify the driver of the type of fault:

• F - transmission control module (TCM) out of order and running in emergency mode.
• H - The TCM is defective, operating in emergency mode and the transmission has overheated, reaching a temperature of more than 137°C.
• E - TCM has stopped transmitting data on the CAN bus due to a CAN bus failure or due to transmission overheating (temperature over 140°С).

Manual Transmission

The gearshift display is designed to show the current gearshift position on manual transmission models. During normal operation, the display shows symbols 1, 2, 3, 4, 5, 6 and N for neutral.

The gear selector position display may also show information about manual transmission problems. The following letter is displayed to notify the driver of a malfunction:

• E - The gear lever position sensor is defective.

PRND and Sport display

The PRND symbol display is only active on vehicles with automatic transmission. The TCM reports the current gear selector position to the instrument cluster via the CAN bus. This information is used by the instrument panel to display the current selector lever position.

If the selector is moved to the SPORT position, the icon will be displayed on the LCD "Sport". If the selector is then moved forward or backward, the transmission shifts to CommandShift™ mode, icon "Sport" disappears and the manually selected gear is shown in the gear display.

Service interval indicator (SII)

The service interval indicator is located in the information display. This display provides information that alerts the driver to upcoming maintenance.


The service interval indicator is displayed for 3 seconds when the ignition is switched on. The service interval is set by the dealer using a Land Rover approved diagnostic system or manual operation, and once set, mileage and time per day are counted down to the next service.

Service intervals vary depending on the market and the engine installed in the vehicle. For some countries in Eastern Europe, South America, the Middle East, and Oceania, the SII indicator is off.

Distance to maintenance

The distance remaining to service is calculated by the instrument cluster based on the current odometer reading and the odometer reading stored the last time the service interval counter was reset. The instrument panel uses these two values to calculate the distance remaining until the next service. The remaining distance value is used to determine when the oil change indicator comes on.

The distance traveled is displayed to the nearest 50 km or 25 miles, depending on the vehicle's market. If the service interval counter goes over 0, the instrument panel keeps counting and the remaining distance is displayed as a negative value.

The value at which the display shows the distance remaining until the next maintenance is 1000 km (600 miles) or 30 days depending on the market and stored in the vehicle configuration file (CCF).

Driver warning

When the instrument panel receives an ignition-on signal, the instrument software checks to see if the conditions for displaying service messages are met to alert the driver. If these conditions are met, the corresponding service messages are shown on the information display for 5 seconds. After 5 seconds, the information display shows the normal odometer and trip odometer readings.

Zeroing procedure

There are two ways to reset the service interval indicator to its original position. A Land Rover approved diagnostic system can be connected to the vehicle to perform diagnostics, and a manual reset procedure using the odometer reset button on the instrument panel can also be used.

Manual reset procedure

• Press and hold the odometer reset button.
• Turn the ignition key to position II.
• C. If the SII function is enabled, the information display flashes for 5 seconds "SERVICE" (maintenance), and then displayed permanently. If the SII function is not enabled, the information display shows the normal odometer and trip odometer readings.
• D. If the reset button is released before 10 seconds have elapsed from the start of the reset mode, the display will show the message "DIST". If the reset button is not released after 10 seconds, the instrument panel will exit the manual reset procedure.
• If the reset button is not released after 10 seconds, the instrument panel will exit the manual reset procedure.
• E. If it is necessary to reset the oil change counter, press the odometer reset button within 10 seconds of releasing it in the previous step and hold it for more than 5 seconds. The display will show the message for 5 seconds "RST", after which the oil change counter will be reset to zero, then the display will show the message "END".
• F. If the reset button is pressed for 5 seconds, the display will exit the reset procedure.
• G. If the reset button is pressed for less than 10 seconds, the information display will exit the reset procedure.
