Gauge Pack - Description

DESCRIPTION

The instrument cluster assembly houses 4 analog gauges standard on all models and, has provisions for up to 19 International Control and Display Symbol icon indicators that are all controlled by the Cab Compartment Node (CCN). For more information on the icon indicators, Instrument Cluster Indicators - Description. The gauge graphics are white and gray against a black field except for the two red graduations at the high end of the gauge scale on the engine temperature gauge, and the low end on the gauge scale on the fuel level gauge. The tachometer has several red graduations at the high end of the gauge scale that designate the red line area, making them clearly visible within the instrument cluster in daylight.

The instrument cluster includes the following analog gauges:

- Engine Temperature Gauge (25)
- Fuel Gauge (19)
- Speedometer (15)
- Tachometer (1)

ENGINE TEMPERATURE

The standard equipment engine temperature gauge is located in the lower quadrant of the tachometer. The gauge consists of a movable gauge needle or pointer controlled by the CCN circuitry and a fixed 90 degree gauge scale on the cluster overlay that reads left-to-right from C (or Cold) to H (or Hot). for all vehicles. An International Control and Display Symbol icon for Engine Coolant Temperature is located on the cluster overlay, directly above the hub of the gauge needle.International Control And Display Symbols for more information.

FUEL LEVEL

A fuel gauge is standard equipment on all instrument clusters. This gauge is located in the lower quadrant of the speedometer. Similar to the engine temperature gauge, the fuel level gauge consists of a movable gauge needle or pointer controlled by the CCN circuitry and a fixed 90 degree gauge scale on the cluster overlay that reads left-to-right from E (or Empty) to F (or Full). The International Control and Display Symbol icon for Fuel is located on the cluster overlay, directly above the hub of the gauge needle. An arrowhead pointed to the left side of the vehicle is imprinted on the cluster overlay next to the Fuel icon on the gauge to provide the driver with a reminder as to the location of the fuel filler access.

SPEEDOMETER

Standard equipment on all instrument clusters, the speedometer is located to the right of center in the instrument cluster. The speedometer consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 210 degree primary scale on the gauge dial face. For all vehicles the speedometer reads left-to-right either from 0 to 140 mph, or from 0 to 240 km/h, depending upon the market for which the vehicle is manufactured. Each version also has a secondary inner scale on the gauge dial face that provides the equivalent opposite units from the primary scale. On all vehicles, text appearing on the cluster overlay above the hub of the speedometer needle abbreviates the unit of measure for the primary scale (either MPH or km/h), and text inside the low end of the secondary scale indicates the unit of measure for that scale.

TACHOMETER

The standard equipment tachometer is located to the left of center in the instrument cluster. The tachometer consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 210 degree scale. On all gasoline vehicles, the tachometer reads left-to-right from 0 to 7 and from 0 to 5 on diesel equipped models. On all vehicles, the text RPM X 1000 imprinted on the cluster overlay directly above the hub of the tachometer needle. This text identifies that each number on the tachometer scale is to be multiplied by 1000 rpm.

When illuminated by the cluster illumination lighting, the white and gray text and graphics as well as the red graphics still appear the same, the red gauge needles have internal optical illumination. Gauge illumination is provided by dimmer controlled Light Emitting Diode (LED) units soldered onto the CCN circuit board. The Gauge set and indicators shown above are an integrated part of the CCN, therefore are only serviced as a unit with the instrument cluster. The cluster lens and the cluster hood and mask unit are the only components of the instrument cluster assembly that can be serviced separately.
