Driver Information Center (DIC) Description and Operation: Notes

The driver information center (DIC) displays important vehicle information when it first powers up. The DIC is also used to display Odometer and Outside Air Temperature when other important vehicle information is not being displayed. The DIC switches are hard wired to and read by the IPC. The BCM is responsible for driving and processing the DIC display through GMLAN serial data. The BCM is responsible for reading the outside air temperature (OAT) and season odometer. The outside air temperature and season odometer is transmitted to the IPC over GMLAN for display in the DIC. The OAT data is transmitted in degrees Celsius and the cluster is responsible for converting the outside air temperature (OAT) to Fahrenheit.

There are 2 DIC buttons on the instrument panel cluster (IPC):

• INFO
• RESET/SELECT

The 2 DIC buttons however provide 3 switch functions. Pressing the INFO and RESET/SELECT button at the same time provides the MENU switch function.
