Driver/Vehicle Information Display: Description and Operation
Driver Information Center (DIC) Description and Operation
The driver information center (DIC) displays the driver identifier greeting for 5 seconds when it first powers up. If enabled through Options, the DIC
then returns to the last display status before no power condition.
There are 4 buttons on the DIC.

Fuel
Press this button to display fuel information such as:
*
Fuel Range
*
Average Fuel Economy
*
Instantaneous Fuel Economy
Fuel Range
This message indicates the estimated distance that the vehicle can travel under the current fuel economy and fuel level conditions since the last battery
connection to the IPC. Fuel Range is calculated using the equation: Fuel Range = Distance Sum/Fuel Sum.
*
Distance Sum = The accumulated distance travelled since the last reset of this value.
*
Fuel Sum = The accumulated fuel delivered since the last reset of this value
The ECM sends the fuel range value to the BCM. The instrument panel cluster (IPC) receives a serial data message from the BCM with the fuel
information. The fuel range value is retained during ignition OFF and can be changed between English and Metric units by pressing the English/Metric
button on the driver information center (DIC) switch. The Fuel Range display cannot be reset. Whenever the calculated fuel range is less than 64 Km/h
(39.8 miles) RANGE-LOW is displayed.
Average Fuel Economy
Average fuel economy is calculated using the equation: AFE = Distance/Fuel
*
Distance = The accumulated distance travelled since the last reset of this value
*
Fuel = The accumulated fuel consumption since the last reset of this value
The ECM sends the average fuel economy serial data message to the BCM. The instrument panel cluster (IPC) receives a serial data message from the
BCM regarding fuel usage information. The value of this mode is retained during ignition OFF and can be changed between English units and metric
units by pressing the English/Metric button on the DIC switch. Press and hold the reset button on the driver information center (DIC) switch for 1 second
in order to reset the AFE display.
Instantaneous Fuel Economy (IFE)
Instantaneous fuel economy (IFE) is calculated using the equation: IFE = Distance/Fuel.
*
Distance = The accumulated distance travelled for the last 2 seconds
*
Fuel = The accumulated fuel delivered for the last 2 seconds
The instrument panel cluster (IPC) receives a serial message from the BCM with fuel level information. The distance information is calculated by the
IPC using the vehicle speed information from the ECM. These values are retained during ignition OFF and can be changed between English and Metric
units by pressing the English/Metric button on the driver information center (DIC) switch. The IFE display cannot be reset.
Gages
The gages button is used in order to scroll the following DIC menus:
