Warning Chimes

The warning chimes provide the driver with audible warnings that act as reminders and supplemental alerts to visual IPC indications (gauges, indicators and message center warnings). The IPC controls all warning chimes based on messages received from external modules.

The warning chimes are an integral part of the IPC that receives and acts upon much of the same information that is used to operate the IPC gauges, informational indicators, warning indicators and message center warnings. The IPC prioritizes the chimes according to a preset hierarchy programmed into the IPC software. When more than one chime request is received by the IPC, the most important chime sounds. If a lower priority chime is currently sounding, the higher priority request takes over and replaces the lower priority chime.

The IPC acts as the arbitrator for all chimes. When a multimedia system is present in the vehicle, all chimes, except for the turn signal tick-tock, sound through the audio speakers. If a multimedia system is not present, all chimes sound through the IPC.

NOTE: There are instances where some chimes may sound through the IPC and should not be interpreted as a fault in the audio system. An example might be when the ignition is off, with the key in the ignition and the driver door ajar. In this instance, the audio system is offline and the key-in-ignition chime defaults to the IPC.

The IPC also acts as a backup. In the event of an audio system chime failure, the IPC sounds all chimes that are required.
