Chime Warning System
A chime warning system is standard factory-installed equipment. The chime warning system uses an electromechanical transducer and an electromechanical relay that are soldered onto the circuit board inside of the Instrument Panel Cluster (IPC) to provide audible indications of various vehicle conditions that may require the attention of the vehicle operator or occupants.
The electromechanical transducer uses one frequency for all chime features. The IPC utilizes electronic chime request messages received from other modules in the vehicle over the Controller Area Network (CAN) data bus along with hardwired inputs to monitor many sensors and switches throughout the vehicle. In response to those inputs, the circuitry and programming of the IPC allow it to control the audible outputs that are produced through its on-board transducer and relay.
The IPC is capable of producing the following audible outputs:
- Single Short Chime Tone - A single short chime tone.
- Single Long Chime Tone - A single long (about 1 second in duration) chime tone.
- Repetitive Chime - Repeated chime tones that are issued at a slow rate of about 90 chimes per minute.
The IPC chime warning system circuits and components cannot be adjusted or repaired. If the circuitry, the on-board transducer or the relay are damaged or ineffective, the IPC unit must be replaced.
This vehicle is also equipped with a backup alarm module (1). Backup alarms are designed to provide a warning sound to signal that the vehicle is reversing.
