Uplevel Cluster

During vehicle start-up IPC sends a class 2 serial data message to BCM indicating it is an uplevel cluster. When Driver Information Center (DIC) menu is set in "Personalization Press Set to Begin" menu and vehicle is in PARK, IPC sends a class 2 serial data message to BCM if SET button is pressed on DIC. Upon receipt of class 2 serial data message from BCM, cluster activates program mode indicator in message center. IPC will also receive a class 2 serial data message from BCM indicating which message shall be displayed. Then any time mode or set button is pressed IPC sends a class 2 serial data message to BCM. IPC continues to display message requested by BCM until BCM commands off or IPC receives a class 2 serial data message indicating vehicle is moving. IPC exits from personalization and returns to top of menu that displays temperature and compass. IPC also turns off program mode indicator.
