Odometer

Odometer

The odometer displays the total distance which the vehicle has travelled. This is calculated by the processor using the wheel speed signals received from the ABS module. The total mileage information is made available to other systems on the I and K Buses and is only transmitted in kilometers, irrespective of market configuration.

The odometer display can show distances travelled up to 999,999 miles or kilometers. When the ignition is off, pressing the left hand instrument cluster button, will allow the odometer reading to be displayed for 25 seconds.

The total distance is also recorded in the instrument cluster EEPROM and RAM. This is recorded after every 2 kilometers travelled and transmitted to the LCM at every ignition off cycle. The LCM stores this information in 100 kilometer intervals and the discrepancy between the instrument cluster and the LCM cannot exceed 2000 kilometers. This data is stored and compared to that in the instrument cluster to protect against illegal alteration of the odometer readings.
