Abstract
A vehicle maintenance interval monitor allows selection of mileage intervals between servicing for a number of individual maintenance items. The monitor is computerized and has connections only to the vehicle'"'"'s battery and ignition circuits. The miles traveled are computed by determining the running time of the vehicle and multiplying this time by a speed factor. When a service interval has been completed the monitor provides a suitable warning indication.
