Driver/Vehicle Information Display: Description and Operation
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.
