Abstract

Abstract An incremental count display system having a display (14) for displaying odometer information and trip odometer information. The display includes a display overflow indicia (21) that will not be permanently activated unless the odometer itself has been factory preset to an initial starting point of other than zero. Otherwise, the overflow indicia (21) must be reset with each display cycle. The trip odometer provides for an accurate count of trip mileage, even during a trip that includes an odometer memory rollover cycle. In addition, the trip odometer display makes use of a masking technique to avoid automatically writing to non-volatile memory (12). Also, an error indicia can be displayed in response to early failure detection.
