Forward Collision Warning 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 forward collision warning chime warns that a forward collision potential has been detected or the Cruise Control Module (C-CM) detects a forward collision warning system concern. Once the forward collision system detects a possible forward collision, the Cruise Control Module (C-CM) sends the HUD module the heads up flash rate message to flash the forward collision warning, and the forward collision warning message request to the IPC through the GWM to sound a 0.25-second chime tone 12 times.

The forward collision warning system and chime can be disabled or turned off using the message center. When MyKey® is in use, the driver cannot configure the forward collision warning system or chime off. When the driver disables the forward collision warning chime, the Cruise Control Module (C-CM) sends the IPC the forward collision chime request through the GWM to sound a 0.25-second chime tone 12 times at 50% volume. The forward collision warning chime and confirmation chime are both sounded through the front speakers.

The IPC receives the forward collision warning message request and the forward collision chime request from the GWM over the High Speed Controller Area Network 3 (HS3-CAN).

The GWM receives the forward collision warning message request and the forward collision chime request from the Cruise Control Module (C-CM) over the High Speed Controller Area Network 2 (HS2-CAN).

When a chime request is received, the IPC sends the IPC chime request message to the ACM and the audio DSP to sound the chime.
