Message Center Warning Chime

The message center warning chime feature draws the driver's attention to the message center display to view new warning messages. There are 3 different message center warning chime types that are defined by the length of the chime tone, which are designed to create a greater sense of urgency based on the nature of the condition and message displayed in the message center.

• Informational (1-second chime)
• Soft warning (0.5-second chime)
• Hard warning (0.25-second chime)

When a new message request is received, the IPC  sends the IPC  chime request message to the ACM  and the audio DSP  to sound the chime.
