Vacuum-Fluorescent Displays
The CCN includes the following Vacuum-Fluorescent Displays (VFDs):
- Odometer and Gear Selector Indicator Displays (21) - includes Cruise indicator.
- Compass Mini-Trip Computer (23) - optional except Chrysler and Dodge base clusters
- Electronic Vehicle Information Center Display (18) - optional
The odometer and trip odometer information are not displayed simultaneously. The trip odometer reset switch on the instrument cluster circuit board toggles the display between odometer and trip odometer modes by depressing the odometer/trip odometer switch button that extends through the lower edge of the cluster lens, just to the right of the odometer VFD. When the trip odometer information is displayed, the text TRIP A or TRIP B is also illuminated in the lower right corner of the odometer/trip odometer VFD in a blue-green color and at the same lighting level as the trip odometer information.
The odometer and trip odometer information are stored in the instrument cluster memory. This information can be increased when the proper inputs are provided to the instrument cluster, but the information cannot be decreased. The odometer can display values up to 999, 999 kilometers (999, 999 miles). The odometer latches at these values, and will not roll over to zero. The trip odometer can display values up to 999.9 kilometers (999.9 miles) before it rolls over to zero.
The odometer display does not show leading zeroes, does not have a decimal point and will not show values less than a full unit (kilometer or mile). The unit of measure (km or miles ) for the odometer display is not shown in the VFD. The unit of measure for the instrument cluster odometer/trip odometer is selected at the time that it is manufactured, and cannot be changed. The odometer has a RENTAL CAR mode, which will illuminate the odometer information in the VFD whenever the driver side front door is opened with the ignition switch in the OFF or ACCESSORY positions.
The CCN provides support for the optional CMTC by calculating average fuel economy, distance to empty and outside temperature values and storing trip odometer and elapsed ignition-ON time data. The CCN receives data and reset requests from the CMTC switches and displays the appropriate information in the CMTC VFD unit.
The CCN provides support for each of the functions and features of the Electronic Vehicle Information Center (EVIC) display. This includes support for the compass, thermometer and audio system mode, customer programmable features, textual warnings, premium Tire Pressure Monitor (TPM), trip computer.
During daylight hours (exterior lamps are OFF) the VFDs are illuminated at full brightness for clear visibility. At night (exterior lamps are ON), the VFD lighting level is adjusted with the other cluster general illumination lamps using the panel lamps dimmer thumbwheel of the headlamp switch on the instrument panel. However, a PARADE mode position of the thumbwheel allows the VFD to be illuminated at full brightness if the exterior lamps are turned ON during daylight hours.
