When the driver information center (DIC) powers up it will display all segments on for 2 seconds. Then the DIC will return to display status it had before no power condition. In the absence of vehicle communications, a double dash (--) displays in the digits section. An error of the speed sensor or fuel sender will cause -E- to be displayed.
There are 2 buttons on the DIC.
| • | RESET button |
| • | MODE button |
RESET Button
You can reset the AVG ECON, FUEL USED or AVG SPEED trip computer modes by pressing and holding the RESET button for three seconds while you are in the mode you wish to reset. A chime will sound to confirm that your requested change has been made and all the segments of the display will briefly light up. To change the display to a metric or English reading, press the RESET and MODE buttons at the same time. Hold them down for three seconds, and the display will change. A chime will be heard to confirm the new selection. The DIC will send a class 2 message to the IPC to change the units displayed in the odometer.
MODE Button
The display format for each mode is indicated in the following table:
Parameter | Update Range | Range | Reset Value | Units |
|---|---|---|---|---|
Average Fuel Economy | 2 seconds | 0.0-99.9 | 0.0 | MPG or LTR/100 KM |
Instant Fuel Economy | 1 second | 0-99 | N/A | MPGAL or LTR/100 KM |
Trip Range | 8 seconds | 40-000 (LO,40) | N/A | MI or KM |
Fuel Used | 0.1 Gal/L | 0.0-999 | 0.0 | GAL or LTR |
Average Speed | 2 seconds | 0.0-99.9 | 0.0 | MPH or KMPH |
Pressing the MODE button changes the modes of operation for the DIC. There are seven display modes available.
| • | Off -- No driver information is displayed in this mode of operation. |
| • | Compass/Temperature |
| • | Average Fuel Economy (AFE) |
| • | Instantaneous Fuel Economy (IFE) |
| • | Trip Range |
| • | Fuel Used |
| • | Average Speed |
Compass/Temperature Mode
This mode displays an 8 point compass heading on the left hand side of the DIC. The compass will display the current vehicle direction relative to one of 8 compass headings using N, NE, E, SE, S, SW, W, and NW for the readout. The ambient temperature displays on the right hand side of the DIC. If the ambient temperature is below 3°C (37°F), the temperature reading will toggle between displaying the outside temperature and the word ICE for two minutes. If the temperature is less than minus 40°F for more than 2 seconds, OC will display. If the temperature is above 140°F for more than 2 seconds, SC will be displayed. If OC or SC is displayed DTC's will be set. For compass calibration and compass magnetic variation adjustment refer to Electronic Compass Calibration .
Average Fuel Economy (AVG)
AFE is calculated as the ratio between the following values:
| • | AFE=Distance/Fuel |
| • | Distance=The accumulated distance since the last AFE reset |
| • | Fuel=The accumulated fuel consumption since the last AFE reset |
You can reset the AFE mode by pressing the RESET button for more than 3 seconds while in this mode. The value of this mode is retained during ignition OFF.
Instantaneous Fuel Economy (INST)
Instantaneous fuel economy is calculated as the ratio between the following values:
| • | IFE=Distance/Fuel |
| • | Distance=The accumulated distance since last update |
| • | Fuel=The accumulated fuel delivered since last update |
You cannot reset the IFE mode. The value of this mode is retained during ignition OFF.
Trip Range (RANGE)
Trip Range is calculated between the following values:
| • | Trip Range=AFE x Fuel Remaining |
| • | Fuel Remaining=Fuel sender value of available fuel |
You cannot reset the Trip Range mode. The value of this mode is retained during ignition OFF.
Fuel Used
The DIC calculates and displays the total amount of fuel used since the last reset operation.
You can reset the Fuel Used mode by pressing the RESET button for more than 3 seconds while in this mode. The value of this mode is retained during ignition OFF.
Average Speed (AVG SPEED)
Average speed is calculated as the ratio between the following values:
| • | Average Speed=Distance/Ignition On |
| • | Distance=Accumulated distance since last reset |
| • | Ignition On=Accumulated ignition on time since last reset |
Ignition on time is measured from the time that the ignition is turned ON, to the time when the ignition is turned OFF.
You can reset the Average Speed mode by pressing the RESET button for more than 3 seconds while in this mode. The value of this mode is retained during ignition OFF.
Dimming Control
Display dimming for the DIC follows the radio dimming characteristics. Upon activation of the parklamps, the display steps from maximum brightness to dim. While in the dim mode, further dimming is controlled by the PWM Dimming Signal of the IP dimming control. The display goes blank upon lowest dimming request of the dimming control.
