Audible Warnings Description and Operation: Notes

The audible warnings alert the driver of a system concern or a critical vehicle condition. The instrument panel cluster (IPC) generates the audible warnings through a speaker. The IPC receives audible warning requests via the GMLAN serial data line. If the IPC receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:

• Fast rate chime (200 pulses per minute)
• Medium rate chime (150 pulses per minute)
• Slow rate chime (50 pulses per minute)
• Single chime
