Warning Chimes: Overview

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

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 deviation from this strategy is the air bag warning chime, which alerts the driver that the primary alerting system (air bag warning indicator) does not operate. 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 input and used to operate the IPC gauges, 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.
