Driver Information Center (DIC) Description and Operation: Notes

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

The driver information center (DIC) displays important vehicle information. The DIC is also used to display the vehicle odometer and outside air temperature when other important vehicle information is not being displayed. The DIC switches are hardwired to and read by the instrument panel cluster (IPC). Battery power is provided to the DIC switch via the instrument panel cluster (IPC) with the DIC switch signal circuit pulled up to battery voltage in the IPC. The battery positive voltage circuit is fused in the body control module (BCM). The BCM is responsible for driving and processing the DIC display through the serial data circuit. 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 the serial data circuit 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
SET/RESET

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