Message Center - Overview. Description and Operation

Overview

The message center is an integral part of the IPC that receives and processes much of the same information that is input to and used by the IPC (gauges, information indicators and warning indicators). The message center uses both hardwired and network inputs to receive information. Message center functionality is controlled through the message center switch (part of the left steering wheel switch pod).

At any time when conditions requiring a warning message are present, the message center replaces the last selected display with the new warning display. After a reset or removal of the message, the message center returns to the last selected display. When multiple warnings are present, the message center cycles between messages, displaying each warning for approximately 4 seconds. Warning messages are also typically linked to other IPC outputs (gauges, information indicators, and RTT (Message Center) indicators). For example, when the BCM detects a low brake fluid condition, the BCM sends a request to the IPC through the GWM to turn on the brake warning indicator and to display the LOW BRAKE FLUID message in the message center. This allows the message center to be a more informative complement to the IPC gauges and indicators.

System warning messages alert the operator to possible vehicle system problems or malfunctions. System warning messages may stand alone, but are often associated with another form of indication, such as a gauge or indicator. The Message Center displays the last selected function if there are no additional warning messages. After a warning message is displayed, it must be acknowledged to restore full Message Center functionality by pressing the OK button to confirm and clear the warning message. For a complete list of displayed warning messages, refer to the Message Center section of the Owner's Manual.
