Indicators, Instrument Cluster: Description
The Electronic Stability Control (ESC) may also be referred to as Electronic Stability Program (ESP) depending on the vehicle model year and configuration. Certain other components may also reference ESP, ESC or use the traction control ISO symbol.
The instrument cluster assembly has provisions for up to 25 International Control and Display Symbol icon indicators and 4 analog gauges, that are all controlled by the Cab Compartment Node (CCN) and standard on all models. Refer to GAUGE PACK, INSTRUMENT CLUSTER, DESCRIPTION . Some of the indicators are automatically configured when the CCN is connected to the vehicle's electrical system for compatibility with certain optional equipment or equipment required for regulatory purposes in certain markets. While each instrument cluster may have provisions for indicators to support every available option, the configurable indicators will not function in vehicles that do not have the equipment that an indicator supports.
The instrument cluster includes provisions for the following indicators:
- Airbag Indicator (14)
- Ajar Indicators - text in odometer display (25) for doors and swing gate
- Antilock Brake System (ABS) Indicator (13)
- Brake Indicator (11) - text only for U.S. market, icon only for markets outside U.S.
- Change Oil Indicator - textual message in odometer display (25) on all domestic market vehicles and only certain export market vehicles equipped with a 2.8L diesel engine and an optional diesel particulate filter

The instrument cluster also includes the following Vacuum Florescent Display (VFD) units:
- Compass Mini-Trip Computer Display (34)
- Odometer Display (25) - includes Cruise indicator (17), Gear Selector indicator (15), Malfunction Indicator Lamp (MIL) (27) (domestic market vehicles only), Off Road indicator (26) (Not Used), Push Button (24), Tire Pressure Monitor (TPM) indicator (19) and 4WD indicator (18) (domestic market vehicles only).
For more information on the International Control and Display Symbol icons. Refer to INTERNATIONAL VEHICLE CONTROL AND DISPLAY SYMBOLS, DESCRIPTION .
Each indicator in the instrument cluster, except those located within a VFD unit, is illuminated by a dedicated Light Emitting Diode (LED) that is soldered onto the CCN electronic circuit board. Cluster illumination is accomplished by several dimmable LED units, which illuminate each of the gauge dial faces for visibility when the exterior lighting is turned ON. These LED units as well as the CCN module are serviced only as a complete unit with the instrument cluster and, if damaged or ineffective, the entire instrument cluster assembly must be replaced. The cluster lens and the cluster hood and mask unit are the only components of the instrument cluster assembly that can be serviced separately.
