Circuit/System Description

The Instrument Cluster is equipped with odometers that indicate the distance traveled by the vehicle. One type of odometer is the season odometer where the traveled distance can not be reset by the driver. This information is also stored in the Body Control Module (BCM). In addition to storing the season odometer value for the vehicle, the Instrument Cluster and the BCM store the VIN. Software checks are performed to ensure these modules and their stored season odometer information, can not be moved or transferred between different vehicles.
