The Integrated Center Stack (ICS) consists of the Integrated Center Stack Screen (if equipped) and the Integrated Center Stack Switch Bank. The ICS receives Fused B(+) power directly from a fuse in the Power Distribution Center (PDC). Any operation of the controls in the Switch Bank sends a message to their corresponding modules via a CAN IHS Bus message.
