Land Rover LR3/Discovery 3 Workshop Service & Repair Manuals

overheat temperature of more than 140ºC (284ºF).  

Manual Transmission  
 
The gear position indicator shows the current gear lever position on vehicles with manual transmission. During normal 
operation the display will show 1, 2, 3, 4, 5, 6 and 'N' for neutral. 
 
The gear position indicator can also display manual transmission fault information. The following letter is displayed to 
relay a fault to the driver: 
 

'E' - The transmission gear position sensor has developed a fault.  

PRND and Sport Display 

The PRND display is only active on vehicles with automatic transmission. The instrument cluster receives CAN bus 
messages from the TCM for the current selector lever position. This information is used by the instrument cluster to 
display the current selector lever position. 
 
If the transmission selector lever is moved to the SPORT position, the term 'Sport' is displayed in the LCD. If the selector 
lever is subsequently moved forward or backwards the transmission operates in 'CommandShift™' mode, the 'Sport' 
display goes off and the gear position indicator displays the current selected manual gear. 
 

Service Interval Indicator (SII) 

The service interval indicator is displayed in the information display. This provides information to the driver warning of an 
impending service requirement. 
 
The service interval is displayed for 3 seconds when the ignition is switched on. The service interval is reset by the dealer 
using T4 or a manual reset procedure and, once set, counts down the mileage and time in days to the next service. 
 
The service interval varies depending on market and vehicle engine fitment. In some Eastern European countries, South 
American countries, Middle East and African countries and some Asia Pacific countries the SII is disabled. 
 
Remaining Distance  
 
The remaining distance is calculated by the instrument cluster by using the current odometer value and the last service 
reset odometer value. The instrument cluster uses these two values to calculate the distance remaining to the next 
service. The remaining distance value is used to display the oil service requirement. 
 
The mileage is displayed to the nearest 50 Km or 25 miles depending on the market configuration of the vehicle. If the 
service interval passes zero without being reset, the instrument pack will continue counting down and the remaining 
distance display will show a negative (-) value. 
 
The trigger point for displaying the remaining distance is 600 miles (1000 km) or 30 days or less depending on the market 
configuration of the vehicle and is contained within the Car Configuration File (CCF).  
 
Driver Alert  
 
When an ignition on signal is received by the instrument cluster, the cluster software performs a check to establish if the 
driver service alert thresholds have been reached. If a driver alert threshold has been enabled, the applicable service 
information will be displayed in the information display for 5 seconds. After the 5 second display has elapsed, the 
information display shows the normal odometer and trip information. 
 
Reset Procedure  
 
There are two ways of resetting the service interval indicator. T4 can be connected to the vehicle and diagnostic routine 
performed or a manual reset procedure can performed using the trip rest button on the instrument cluster. 
 
Manual Reset Procedure 

Press and hold the trip reset button.  
Turn the ignition switch on to the ignition position II.  
If the SII function is set in the CCF the information display will flash 'SERVICE' for 5 seconds and then display 
'SERVICE' constantly. If the SII function is not set in the CFF the information display will show the normal
