Warning Chime Characteristics

Each warning chime has unique characteristics that help to identify and differentiate each warning chime. The warning chimes use volume, chime frequency, length of time the chime sounds and the number of chime tones to identify which chime is sounding. The IC prioritizes the chimes according to a preset hierarchy programmed into the IC software. When more than one chime request is received by the IC, 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.

There are 3 different chimes as listed below:

Repetitive
Single tone
Tick-tock

The following table provides a summary of the chime characteristics including the chime priority.

Turn signal left on	Repetitive, 0.37-second duration tones.	On for as long as the RH or LH turn signal is on, the vehicle has travelled 3.2 km (2.0 miles) and the IC receives the chime on command.
