Ford Fiesta: Instrumentation, Message Center and Warning Chimes / Warning Chimes - Overview. Description and Operation

Overview

The warning chimes provide the driver with audible warnings that act as reminders and supplemental alerts to visual IPC indications (gauges and 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 and warning indicators and the message center warning displays. 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.
