Active Park Assist Chimes
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The active park assist audio system chimes are controlled by the IPC. Based on the parking aid chime request message received from the PAM, the IPC prioritizes the incoming chime request and then commands the ACM (for vehicle without Sony® audio system) or the DSP (for vehicle with Sony® audio system) to sound the chime through the audio system speakers. In the event of an audio system fault, the IPC sounds the chimes through an integral speaker. Refer to Warning Chimes - System Operation And Component Description
