CTS V6-2.8L (2006)
Driver/Vehicle Information Display: Description and Operation
DRIVER INFORMATION CENTER (DIC) DESCRIPTION AND OPERATION
The radio displays the current driver ID when it first powers up. The radio then returns to the last display status before no power condition.
There are 4 buttons on the radio:
-
ENG/MET
-
DIC Info
-
Reset
-
Trip
ENG/MET
The ENG/MET button is used in order to change the instrument panel cluster (IPC) displays between English and metric units. The km/h indicator or
the MPH indicator illuminate in the IPC accordingly.
DIC INFO
The DIC INFO button is used in order to navigate through the following driver information center (DIC) modes:
-
Average fuel economy (AFE)
-
Average vehicle speed
-
Battery voltage
-
Engine oil life
-
Fuel range
-
Fuel used
-
Instantaneous fuel economy (IFE)
-
Timer
-
Trip odometer A
-
Trip odometer B
-
Transmission fluid life
Average Fuel Economy (AFE)
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 instrument panel cluster (IPC) receives a class 2 message from the engine control module (ECM) 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 ENG/MET button on the DIC
switch. Press and hold the Reset button on the radio switch for one second in order to reset the AFE display.
Average Vehicle Speed
Average speed is calculated using the equation: Average Speed = Distance/Ignition On
-
Distance = The accumulated distance travelled since the last reset of this value
-
Ignition On = The accumulated ignition on time since the last reset of this value
Ignition on time is measured from the time that the ignition is turned ON to the time when the ignition is turned OFF. The value of this mode is
retained during ignition OFF. Press and hold the Reset button on the radio switch for one second in order to reset the average speed display.
Battery Voltage
The IPC receives a class 2 message from the ECM for battery voltage data. When the battery voltage is below the normal operating range, the DIC
displays BATTERY VOLTAGE LOW and the actual battery voltage. When the battery voltage is greater than the normal operating range, the DIC
displays BATTERY VOLTAGE HIGH and the actual battery voltage. The charging system indicator also illuminates when the battery voltage is
outside the normal operating range.
Engine Oil Life
The ECM sends the oil life remaining percentage to the radio via class 2 serial data messages. The radio displays the current percentage of the GM Oil
Life System as determined by the ECM. When the oil life remaining percentage drops below 10 percent, the radio displays CHANGE ENGINE OIL.
When the engine oil is changed, reset the engine oil life in order to clear the oil life remaining percentage display. Press and hold the Reset button on
the DIC switch for 5 seconds until the radio displays NORMAL 100 percent.
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 reset of
the value. 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
