Driver Information Center (DIC) Description and Operation: Personalization

WARNING: This page is about a different car, the 2019 GMC Savana 3500, 2019 GMC Savana 2500, 2019 Chevrolet Express 3500, and 2019 Chevrolet Express 2500. However, it is still accessible from the selected car via links, so may be relevant.

The personalization switch is used to set personalization features for both the vehicle and the driver. Many of the parameters in the Trip/Fuel menu and the Vehicle Information menu can be programmed through the personalization switch. In addition to the parameters in the Trip/Fuel and Vehicle Information menus, the following features can also be programmed.

Average Fuel Economy 

Average fuel economy is calculated using the equation: AFE = Distance/Fuel

The engine control module (ECM) sends the average fuel economy serial data 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 driver information center (DIC) options menu.

Average Vehicle Speed 

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

Elapsed Time 

The timer records elapsed time starting from activation. When the DIC displays the timer, pressing the Set/Reset switch for 3 seconds 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).

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 X Fuel Total Capacity/Range Fuel Used.

The ECM sends the fuel range value to the IPC. The IPC receives a serial data 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 English/Metric menu. The Fuel Range display cannot be reset. LOW is displayed when fuel range is below a predetermined value.

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 depressing and holding the Set/Reset button for more than 3 seconds. The value of this mode is retained during ignition OFF.

Instantaneous Fuel Economy (IFE) 

Instantaneous fuel economy (IFE) is calculated using the equation: IFE = Distance/Fuel Used.

The IPC receives a serial data 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 accessing the DIC English/Metric menu. The IFE display cannot be reset.

Oil Life Remaining 

The ECM sends the oil life remaining percentage to the IPC via a serial data message. The instrument panel cluster receives a serial data message indicating the engine oil life remaining. The DIC displays the current percentage of the GM Oil Life System as determined by the ECM. When the oil life remaining percentage drops below 5 percent, the DIC displays CHANGE ENGINE OIL SOON. When the engine oil is changed, reset the GM Oil Life System. Refer to GM Oil Life System Resetting (Without Scan Tool) , or GM Oil Life System Resetting (With Scan Tool) .

Tire Pressure Monitor 

The IPC receives a serial data message from the tire pressure monitoring (TPM) system for front and rear tire pressure data. The DIC will display the pressure for each of the front and rear tires. When a tire with low air pressure is present, the DIC displays XXXX XXXX TIRE PRESSURE LOW.
