Automatically resetting oil level warning light after oil change involves comparing sensor signal with previously stored value, selectively resetting lamp depending on comparison result

摘要

The method involves receiving a current signal from a sensor (18) representing the current oil parameter value, comparing it with a previously stored value and selectively resetting the oil level warning light (22) depending on the result of the comparison. The level sensor is periodically stimulated to produce the current oil level value. Independent claims are also included for the following: a computer program device.
