Information And Message Center: Overview: Notes

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, informational indicators, and warning indicators. The message center uses hardwired and network-based inputs to receive information. The message center functionality is controlled through the message center switch (part of the LH steering wheel switch).

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 outputs of the IPC (gauges, informational indicators, and message center indicators). For example, when the BCM detects a low brake fluid condition, the BCM sends the IPC a request to illuminate the brake warning indicator and a request to display the LOW BRAKE FLUID message in the message center. This allows the message center to be a more informative supplement to the IPC gauges and indicators.
