Remaining Distance

Remaining distance shows the distance remaining until the next service is required. This is displayed in the selected units of the Odometer and Trip counter. If the service is overdue then the display will show how many miles past the service the vehicle is. This is indicated by displaying a '-'  (minus symbol) next to the remaining distance. The remaining distance will not show any leading zeros and the minus sign will remain next to the most significant digit, for example:

• -50 km
• -250 km
• -1250 km

The displayed distance will always be quantified to the nearest 50 km or 25 miles depending on the selected display units. The remaining distance is calculated from 3 inputs; fuel used, recommended distance between services and the quantity of fuel to be used between service intervals.

The formula is:

Remaining Distance = Recommended distance * (SI fuel quantity - fuel consumed) / SI fuel quantity

The advantages are that the formula is easily adapted for different engines by supplying different values for the recommended distance and SI fuel quantity, and that the remaining distance will reduce more quickly if the engine is subjected to more arduous usage. Equally the service distance may be extended by moderate usage. The values of recommended distance and SI fuel quantity will be stored in the IKE memory. To prevent the remaining distance counter from being reset in the case of loss of power or software reset, the accumulated fuel used is stored in IKE memory at least once every 2 km synchronized with the Odometer distance storage.
