Instrument Cluster - Description

DESCRIPTION

The instrument cluster for this vehicle, located in the instrument panel directly in front of the driver, above the steering column opening. The instrument cluster includes the hardware and software necessary to serve as the electronic body control module and is also known as the Cab Compartment Node (CCN). The CCN, including the mounts and the electrical connections, are concealed within the instrument panel behind the cluster bezel. Besides analog gauges and indicators, the cluster incorporates two digital Vacuum Fluorescent Display (VFD) units for displaying odometer/trip odometer information, engine hours, automatic transmission gear selector position (PRNDL), several warning or reminder indications and certain diagnostic information, and the display for the Electronic Vehicle Information Center (EVIC).

Several versions of the CCN are offered. These versions accommodate all of the variations of optional equipment and regulatory requirements for the various markets in which the vehicle will be offered. The microprocessor-based CCN utilizes integrated circuitry and information carried on the Controller Area Network (CAN) data bus along with several hard wired analog and multiplexed inputs to monitor sensors and switches throughout the vehicle. In response to those inputs, the internal circuitry and programming of the CCN allow it to control and integrate many electronic functions and features of the vehicle through both hard wired outputs and the transmission of electronic message outputs to other electronic modules in the vehicle over the CAN/LIN data bus Communication - Description.

The CCN houses four analog gauges and has provisions for up to twenty-three indicators. All of the CCN indicators are automatically configured when the CCN is connected to the vehicle electrical system for compatibility with certain optional equipment or equipment required for regulatory purposes in certain markets. While each CCN may have provisions for indicators to support every available option, the configurable indicators will not be functional in a vehicle that does not have the equipment that an indicator supports.

Each indicator in the CCN, except those located within the VFD units, is illuminated by a dedicated LED that is soldered onto the CCN electronic circuit board. Cluster illumination is accomplished by dimmable LED back lighting, which illuminates each of the gauges for visibility when the exterior lighting is turned on. The LED units are not available for service replacement and, if damaged or faulty, the entire CCN must be replaced.

The CCN is serviced only as a complete unit. The CCN cannot be adjusted or repaired. If a gauge, an LED indicator, a VFD unit, the electronic circuit board, the circuit board hardware, the cluster overlay, or the CCN housing are damaged or faulty, the entire CCN must be replaced. The cluster lens, hood and mask unit are available for separate service replacement.
