Active Park Assist Chime
WARNING: This page is about a different car, the 2019 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The active park assist system uses informational and instructional messages displayed in the FCDIM to direct the driver's interaction with the system. The active park assist system chimes alert or to draw the driver's attention to the requested actions as displayed in the FCDIM messages. The active park assist chime sounds through the front speakers.
The IPC receives the parking aid chime request from the GWM over the High Speed Controller Area Network 3 (HS3-CAN).
The GWM receives the parking aid chime request from the Parking Aid Module (PAM) over the High Speed Controller Area Network 1 (HS1-CAN).
The IPC then sends the IPC chime request message to the ACM and the audio DSP to sound the chime.
