Audible Warnings Description and Operation: Notes

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The audible warnings alert the driver of a system concern or a critical vehicle condition. The body control module (BCM) generates the audible warnings. The BCM receives audible warning requests via the class 2 serial data line or the controller area network (CAN) data line. 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
