General Description

The audible warnings alert the driver of a system concern or a critical vehicle condition. The Body Control Module (BCM) generates the audible warnings based on a request via the class 2 serial data line or determined by the BCM itself in some instances such as the Key-In-Ignition warning or the Headlamps On Reminder. If the BCM receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:
1. Fast rate chime (200 pulses per minute)
2. Medium rate chime (150 pulses per minute)
3. Slow rate chime (50 pulses per minute)
4. Single chime
