Information And Message Center
The message center is an integral part of the IPC that receives and acts upon much of the same information that is input and used to operate the IPC gauges, indicators, warning indicators and message center indicators.
Whenever conditions are present that require a warning message, the message center replaces the last selected display with the new warning display. Once the message is reset or cleared, the message center returns to the last selected display. If multiple warnings are present, the message center displays each warning for approximately 4 seconds. Warning messages are also generally associated with other observable IPC indications. For example, when the LH front door is opened, the message center displays the message DRIVER DOOR AJAR along with the door ajar message center warning indicator. This allows the message center to be a more informative supplement to the IPC gauges and indicators.
Another function of the message center is to display message center warning indicators. The message center often displays a warning message and the message center warning indictor at the same time. For example, if the PCM detects low engine oil pressure, the PCM sends a request to the IPC to illuminate the low oil pressure message center indicator and to display LOW OIL PRESSURE in the message center. If multiple warnings are present requiring multiple message center warning indicator displays, the message center cycles or rotates through the displays in the same manner the message center cycles the text messages.
