ABSTRACT:
A method is provided for preventing odometer fraud on a vehicle having a multiplex ring including a plurality of vehicle control modules in electrical communication with each other. The multiplex ring includes a cluster control module with an odometer display. The method includes: a) displaying an odometer mileage variable; b) periodically storing the displayed odometer mileage variable in a non-volatile memory location in the cluster control module; and c) periodically storing the displayed odometer mileage variable in a non-volatile memory location in at least one of the vehicle control modules other than the cluster control module, thereby increasing the level of difficulty of odometer tampering.
