Driver Information Center (DIC)

The driver information center (DIC) in this vehicle is comprised of the following 2 major parts:

    • A driver message center, which is within the IPC
    • A set of buttons which control the display information on the driver message center

Driver Message Center

The bottom portion of the IPC contains a 20 character dot matrix VF display. The VF display is referred to as the driver message center. Use the driver message center in order to display the following 3 types of information:

    • The status messages of driver selectable information
    • Any warning messages
    • The vehicle diagnostic system information

Warning messages are displayed by priority, with the higher priority display messages first. Warning messages may coincide with a DTC being set.

An export ID# accompanies status/warning messages if certain IPC override options set.

Some messages may disable by using the IPC override option settings in the vehicle diagnostic system.

The IPC blanks the parameter values of the messages until the IPC receives valid data from an interacting module.

The IPC displays the parameter values of the messages as dashes if the serial data line or an interacting module are not communicating. A description follows of the button functions for the digital and analog IPCs.
