Instrument Cluster - Description






DESCRIPTION





The instrument cluster (IC)(1) for this vehicle is located directly in front of the driver, above the steering column opening. The mounts and the electrical connections, are concealed within the instrument panel behind various trim panels and the cluster itself. The IC contains various indicators, analog gauges, and a Liquid Crystal Display (LCD), and an integrated circuit board. The LCD displays odometer information, and several indicators, some of which are model dependant.

There are several versions of the IC offered for this vehicle. These versions accommodate all of the variations of optional equipment for the various markets in which the vehicle is offered. The IC may also contain an Electronic Vehicle Information Center (EVIC) option. The EVIC option provides the outside ambient temperature, compass headings, average fuel economy, elapsed time, numerous textual warning messages, reminder indicators, and certain diagnostic information.





The IC can be serviced as several components. The gauges, indicators and electronic circuitry along with the housing itself are only serviced as an assembly, and cannot be adjusted or repaired. If a gauge, LED unit, LCD unit, electronic circuit board, circuit board hardware, cluster overlay, or cluster housing is damaged or ineffective, the entire unit must be replaced. The cluster lenses and hood and mask are available for separate service replacement.

VEHICLE SYSTEMS SUPPORT

AUDIBLE WARNINGS
The IC electronic circuit board is equipped with a piezoelectric speaker and programming that allows it to provide various audible alerts to the vehicle operator. These alerts include single chime tones, and continuous slow or fast tones. An IC can also produce audible clicks that are used to emulate the sound of a conventional turn signal or hazard warning flasher.

FUEL LEVEL DATA
The IC receives a message from the Body Control Module (BCM) over the Control Area Network (CAN) data bus. The IC uses this information to calculate the proper fuel gauge needle position and to control low fuel indicator operation. This information is also transferred over the CAN data bus for use by other electronic modules in the vehicle.

INTERIOR LIGHTING CONTROL
The IC monitors inputs from the interior lighting switch to provide interior lighting control for the instrument cluster, shifter (PRNDL) back lighting, console cup holders, power window and lock switch back lighting, as well as the HVAC rear control lighting. The lighting for Integrated Center Stack (ICS) Screen, as well as the switch-bank and other courtesy lighting throughout the vehicle are all controlled by the BCM. This includes support for timed illuminated entry with theater-style fade-to-off and courtesy illumination defeat features.

VEHICLE WARNING MESSAGES
When the appropriate conditions exist, messages such as "HOOD" (hood ajar), "DOOR" (door ajar), "GATE" (liftgate ajar), "LoCOOL" (low engine coolant), "LoWASH" (low washer fluid), "ESC OFF" (Electronic Stability Control in partial off mode), "NoBUS" (data bus communication fault), or "CHANGE OIL" displays in the LCD display.

CHANGE OIL MESSAGE

Your vehicle is equipped with an engine oil change indicator system. The "CHANGE OIL" message flashes in the instrument cluster odometer for approximately 12 seconds after a single chime has sounded to indicate the next scheduled oil change interval. The engine oil change indicator system is duty cycle based, which means the engine oil change interval may fluctuate dependent upon your personal driving style.

Unless reset, this message continues to display each time you turn the ignition switch to the ON position. To turn off the message temporarily, press and release the TRIP ODOMETER button on the instrument cluster. To reset the oil change indicator system, (after performing the scheduled maintenance) perform the following procedure:

1. Turn the ignition switch to the ON position. (Do not start the engine).
2. Fully press the accelerator pedal slowly three times within 10 seconds.
3. Turn the ignition switch to the LOCK position.
NOTE: If the indicator message illuminates when you start the vehicle, the oil change indicator system did not reset. If necessary, repeat this procedure

ELECTRONIC VEHICLE INFORMATION CENTER (EVIC) DISPLAY

The EVIC system conveniently allows the driver to select a variety of useful information by pressing the MENU and STEP buttons, which are located on the front of the steering wheels left spoke. The EVIC displays information related to the following:

- Compass display
- Outside temperature display
- System Status
- Trip computer functions
- Vehicle information warning message displays
- Economy mode (ECO)

The instrument cluster includes the following LCD unit:





- EVIC LCD Display (14)

The LCD (14) unit is soldered to the electronic circuit board, and comes standard and is located between tachometer on the left and speedometer on the right.

The odometer is located within the LCD and is visible through a window with a smoked lens. The dark lens prevents it from being clearly visible when it is not illuminated. The odometer information is stored in the IC memory. This information can be increased when the proper inputs are provided, 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 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 shown in the LCD in the same white color and at the same lighting level as the odometer values. The unit of measure for the odometer can be selected using the customer programmable features function of the Electronic Vehicle Information Center (EVIC). The odometer has a RENTAL CAR mode, which will illuminate the odometer information in the EVIC whenever either front door is opened with the ignition switch in the OFF or ACCESSORY positions.

During daylight hours (exterior lamps are OFF) the LCD is illuminated at full brightness for clear visibility. At night (exterior lamps are ON), the LCD lighting level is adjusted with the other cluster general illumination lamps using the panel lamps dimmer function of the interior lighting control. However, a PARADE mode position of the control allows the LCD to be illuminated at full brightness if the exterior lamps are turned ON during daylight hours.

Dual trip odometer (Trip A and Trip B) capability is standard equipment on this vehicle. Both trip odometers appear within the LCD display unit. The trip odometer information is stored in the instrument cluster memory. Each trip odometer can display values up to 16099.9 kilometers (9999.9 miles). Each trip odometer will roll over to zero independently when it accumulates these values. The trip odometer minimum value is 0.0 (miles or kilometers) and does have a decimal point to show tenths of a full unit values (miles or kilometers).

The unit of measure (km or miles) for the trip odometer display is shown next to the Trip A or Trip B text in the LCD in the same white color and at the same lighting level as the trip odometer values. The unit of measure for the trip odometer can be selected using the customer programmable features function of the Integrated Center Stack (ICS) screen module.
