ABSTRACT:
A system and method to prevent odometer fraud in a vehicle are described, including determining whether the vehicle is driven for a predetermined period of time, such as an hour, and checking whether input to the odometer is consistent with such determination. For example, if an insufficient number of vehicle speed pulses have been received during the period of time that the vehicle has been driven, then it can be concluded that the vehicle speed pulse input has been removed from the odometer and various fraud prevention actions can be taken, such as changing the odometer display to output “ERROR” or disabling the odometer from working, even after the vehicle speed pulse input is reconnected to the odometer.
