Abstract
A system for automatically resetting an oil condition alarm light after an oil change includes an in-vehicle digital processing apparatus electrically coupled to a warning lamp and to an oil sensor installed in an engine oil pan. The digital processing apparatus further includes a warning lamp reset module to automatically reset the oil sensor following an oil change, based on an oil parameter difference value.
Claims16
A computer-implemented method for automatically resetting an oil alarm lamp after an oil change in a vehicle, the oil alarm lamp being associated with at least one sensor, the method comprising:
- receiving a current signal from the sensor representative of at least one current oil parameter value;
- comparing the current value to a prestored value;
- and
- based on the comparing act, selectively resetting the oil alarm lamp.
A device comprising:
- a computer program storage device readable by a digital processing apparatus;
- and
- a program means on the program storage device and including instructions executable by the digital processing apparatus for performing method acts for determining when an oil change has been undertaken on a vehicle, the method acts comprising:
- comparing at least one current oil parameter value with a prestored oil parameter value;
- and
- based on the comparing act, outputting a signal representative of whether oil has been changed in the vehicle.
