Active Park Assist Chimes
The active park assist audio system chimes are controlled by the IPC . Based the on the parking aid chime request message from the Parking Aid Module (PAM), the IPC will command the audio system to lower the current radio volume and sound a chime through the audio system speakers. In the event of an audio system fault, the IPC will sound the chimes through an integral speaker.
