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 hardwired to and read by the instrument panel cluster (IPC). The body control module (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 OAT to Fahrenheit.
There are 2 DIC buttons on the IPC:
- INFO
- RESET/SELECT
The 2 DIC buttons however provide 3 switch functions. Pressing the INFO and RESET/SELECT button at the same time and holding for 2 seconds will enter the personalization menu.
