Information display (Discovery 3)

The information display is a liquid crystal display. (LCD display), located in the lower right part of the instrument panel. The visible area of the LCD display is 43x20 mm and is divided into seven segments. When the information display is on, its backlight works as follows:

• When you press the trip meter reset button, the odometer lights up and the odometer and trip meter readings are displayed for 20 seconds.
• When the ignition is turned on, the odometer is turned on in the display mode of all functions

With the ignition on and the lights off, the information display is fully illuminated at normal brightness under the control of the ambient light sensor. When the lights are on, the display brightness is reduced to a level determined by the pulse-width dimmer built into the light switch.

The data displayed on the information display is received by the instrument cluster from the control modules of other subsystems in the form of messages via the CAN bus. The odometer and trip meter data are received from the ABS module, the transmission data is received from the transmission control module. (for models with automatic transmission) or from the 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 received from the ABS module.



The 6-digit odometer display can show values up to 999999 miles or kilometers. With the ignition off, the odometer reading can be displayed by pressing the trip meter reset button. The reading is displayed for a short period of time.

The total distance traveled is recorded in the electrically erasable programmable read-only memory (EEPROM) and random access memory (RAM) of the instrument cluster. This ensures that the total distance traveled is retained when the battery is disconnected. The distance is read and written to the memory every 2 kilometers or miles traveled.

Trip odometer

The trip odometer displays the distance traveled since the odometer was last reset. The trip odometer display has four digits, and the fourth digit, representing 1/10 of a mile or kilometer, is separated by a decimal point. The trip odometer can display values up to 999.9 miles or kilometers. When 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 cluster for two seconds. The trip mileage is recorded in RAM, but not in EEPROM, so when the battery is disconnected, this data is lost, and when the battery is reconnected, the counter is set to 000.0.

Gear engaged display

Automatic transmission

The gear position display is designed to show the current position of the gear selector on models with an automatic transmission. During normal operation, the display shows the following symbols: P - Park, R - Reverse, N - Neutral and D - Drive.



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

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

• F - The transmission control module (TCM) is faulty and operating in limp mode.
• H - The TCM is faulty, operating in limp mode and the transmission has overheated, reaching a temperature greater than 137°C.
• E - The TCM has stopped transmitting data on the CAN bus due to a CAN bus failure or due to transmission overheating (temperature over 140°C).

Manual transmission

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

The gear selector position display can also display fault information for the manual transmission. The following letter is displayed to notify the driver of the fault:

• E - The gear lever position sensor is faulty.

PRND and Sport Display

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

When the selector is moved to the SPORT position, the Sport icon is displayed on the LCD display. If the selector is then moved forward or backward, the transmission switches to CommandShift™ mode, the Sport icon disappears and the gear display shows the manually selected gear.

Service Interval Indicator (SII)

The service interval indicator is located in the information display. This display provides information to alert 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 the Land Rover approved diagnostic system or manual operation and once set, the miles and days until the next service are counted down.

Service intervals vary depending on the market and the engine installed in the vehicle. In some Eastern European, South American, Middle Eastern and Oceanic models, the SII indicator is off.

Distance remaining before maintenance

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

The distance travelled is displayed with an accuracy of 50 km or 25 miles, depending on the market of the vehicle. If the service interval counter value passes 0, the instrument cluster continues to count down and the remaining distance is displayed as a negative value.

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

Driver Warning

When the instrument cluster receives a signal to turn on the ignition, the instrument cluster software checks whether the conditions for displaying service messages to alert the driver are met. If these conditions are met, the relevant service messages are displayed on the information display for 5 seconds. After 5 seconds, the normal odometer and trip meter readings are displayed on the information display.

Zeroing order

There are two ways to reset the service interval indicator. A Land Rover approved diagnostic system can be connected to the vehicle to perform diagnostics, or a manual reset procedure can be used using the trip meter reset button on the instrument cluster.

Manual zeroing procedure

• Press and hold the trip meter reset button.
• Turn the ignition key to position II.
• C. When the SII function is on, the message "SERVICE" flashes on the information display for 5 seconds. (maintenance), and then displayed continuously. If the SII function is not turned on, the information display shows the normal odometer and trip meter readings.
• D. If the reset button is released before 10 seconds have passed from the reset mode being activated, the display will show "DIST". If the reset button is not released after 10 seconds, the instrument cluster will exit the manual reset procedure.
• If the reset button is not released after 10 seconds, the instrument cluster 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 after releasing it in the previous step and hold it for more than 5 seconds. The display will show "RST" for 5 seconds, after which the oil change counter will be reset, then the display will show "END".
• F. If the reset button is pressed within 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.
