Driver Information Center (DIC) Description and Operation: Info

The INFO button is used in order to navigate through the following driver information center (DIC) information modes:

• AV SPEED
• ECON
• COOLANT
• FUEL RANGE
• OIL LIFE
• TRIP A
• TRIP B

Other instrument panel cluster (IPC) information displayed in the DIC are Season odometer and Outside Air Temp.

AV 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/SELECT button on the DIC for 1 second in order to reset the average speed display.

ECON 

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 DIC receives a serial data message from the body control module (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. Press and hold the RESET/SELECT button on the DIC switch for 1 second in order to reset the ECON display.

COOLANT 

The DIC receives a serial data message from the BCM requesting the display of the coolant temperature. The coolant temperature is sent to the BCM as determined by the engine control module (ECM) via a serial data message.

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

The DIC receives a serial data message from the BCM with fuel information. The value of this mode is retained during ignition OFF and can be changed between English units and metric units. The FUEL RANGE display cannot be reset.

OIL LIFE 

The engine control module (ECM) sends the oil life remaining percentage to the BCM via serial data message. The DIC receives a serial data message from the BCM indicating the remaining oil life. The DIC displays the current percentage of the GM Oil Life System as determined by the ECM.

TRIP A and TRIP B 

The DIC displays vehicle trip odometer mileage based on the vehicle speed signal (VSS) from the BCM. The trip odometer displays accumulated km (mi) since the last reset of this value. The trip odometer is capable of displaying up to 999.9 km (999.9 mi). Trip odometer information is not retained when the battery is disconnected. Press and hold the INFO button on the DIC for 1 second in order to reset the trip odometer display.
