Chime Warning System: Description

WARNING: This page is about a different car, the 2020 Jeep Renegade. However, it is still accessible from the selected car via links, so may be relevant.

A chime warning system is standard factory-installed equipment. The chime warning system uses an electromechanical transducer that is soldered on to the electronic 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 can produce signals that vary in intensity and frequency, depending on the function being signaled. The microcontroller-based 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.

The IPC chime warning system circuits and components cannot be adjusted or repaired. If the circuitry or the on-board transducer are damaged or ineffective, the IPC unit must be replaced.
