The Instrument Cluster Control (ICC) unit is located on the control panel above the steering column. This electronic module provides visual information to the operator. It contains a group of indicator lights, a data display window, and analog gauges.
The ICC displays operational performance, settings, diagnostics, and alarm information relevant to the vehicle system. It receives information directly from the components and over the CAN network.
