Info Up/Info Down Switch

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

Scroll through any selected driver information center (DIC) switch function by pressing Info Up/Info Down.

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 engine control module (ECM) sends the average fuel economy GMLAN message to the instrument panel cluster (IPC). The value of this mode is retained during ignition OFF and can be changed between English units and metric units by selecting from the DIC trip/fuel information switch.

Average Vehicle Speed

Average vehicle speed is calculated using the equation: Average Speed = AVS Distance/AVS Time

Distance = The accumulated distance travelled since the last reset of this value
Time = The accumulated time since the last reset of this value

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 = Range Distance/Range Fuel Used.

Range Distance = The accumulated distance travelled since the last reset of this value.
Range Fuel Used = The accumulated fuel delivered since the last reset of this value

The ECM sends the fuel range value to the IPC. IPC receives a GMLAN message with fuel information. The fuel range value is retained during ignition OFF and can be changed between English and Metric units by accessing the DIC trip/fuel information switch. The Fuel Range display cannot be reset. LOW is displayed when fuel range is below a predetermined value.

Fuel Used

This message indicates the amount of fuel used since last reset. Fuel Used is calculated using the equation: Fuel Used = Fuel Sum.

Fuel Used = The accumulated fuel used since the last reset of this value.
Fuel Sum = The accumulated fuel sum since the last reset of this value

The ECM sends the fuel used value to the IPC. The IPC receives a GMLAN message with the fuel information. The fuel used value is retained as long as battery power is available to the DIC. The fuel used value can be changed between English and Metric units by accessing the DIC trip/fuel information switch.

Instantaneous Fuel Economy (IFE)

IFE is calculated using the equation: IFE = Distance/Fuel Used.

Distance = The accumulated distance travelled for the last 2 seconds
Fuel = The accumulated fuel delivered for the last 2 seconds

The IPC receives a GMLAN message from the ECM. 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 accessing the DIC trip/fuel information switch. The IFE display cannot be reset.

Trip Timer

The timer records elapsed time starting from activation. When the DIC displays the timer, pressing the SET/RESET switch for 1 second on the DIC resets the timer. Pressing the SET/RESET button on the DIC switch for approximately 1 second starts and stops the timer. The DIC displays the timer in one of the following formats:

The DIC displays the timer in the following format: XX: XX:XX:

The first XX represents hours elapsed, the second XX represents minutes elapsed, and the third XX represents seconds elapsed. The maximum range of the timer is 99 hours, 59 minutes, and 59 seconds. After the maximum range is reached, the timer displays all zeros (00:00:00).

Battery Voltage

Battery voltage data is not determined by the DIC and is not a resettable parameter. The DIC displays (- - -) when an invalid battery data is received or when the IPC experiences a loss GMLAN communications.
