Vehicle Data

The vehicle data parameters are available to the driver when the ignition is ON. The driver navigates through the various parameters displayed on the Driver Information Center (DIC) using the MODE button. Some parameters can be reset using the RESET button.

Some parameters require information from other modules via class 2 serial data messages. If the Instrument Cluster (IPC) has not received data for a parameter when the time has come to display the parameter, the IPC will blank the data on the DIC. If the IPC has determined that a class 2 communication failure with one of the modules exists when the time has come to display the parameter, the IPC will display dashes on the DIC.

The vehicle data parameters are displayed in the following order:
1. Average fuel economy
2. Instantaneous fuel economy
3. Fuel range
4. Fuel used
5. GM oil life system
6. Battery voltage - with Boost Gage
7. Tire pressure monitor
