Abstract: A vehicle monitoring system sequentially monitors a plurality of conditions of vehicle sensors for oil, water, air pressures, temperatures and the like. The system includes sequencing means for sequentially sampling data from each of the plurality of sensors and comparing the sensed data with programmed stored parameter limits representative of fault conditions for each parameter sensed. The system includes means for selecting an individual parameter for continuous display and an override circuit for displaying a nonselected parameter if it reaches a programmed limit. Also, a plurality of operator display select switches are provided and are illuminated such that in the event a detected parameter reaches a stored limit, the select switch associated with that parameter flashes in different colors indicating a warning or an alarm fault condition.
