Indicators, Instrument Cluster: Description: Description: Notes
The Electronic Stability Control (ESC) may also be referred to as Electronic Stability Program (ESP) depending on the vehicle model year and configuration. Certain components may also reference ESP, ESC, or use the traction control symbol.
Each indicator in the instrument cluster, except those located within a VFD unit, is illuminated by a dedicated LED that is soldered onto the instrument cluster electronic circuit board, also known as the Cab Compartment Node (CCN). Cluster illumination is accomplished by several dimmable LED units, which illuminate each of the gauge dial faces for visibility when the ignition switch is in the ON or START positions, or when the exterior lighting is turned ON. These LED units are not available for service replacement, and if damaged or inoperative, the entire CCN must be replaced.
