Lane Keeping Aid Warning System 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 lane keeping aid warning chime alerts the driver they have removed their hands from the steering wheel. The lane keeping aid warning system chime sounds three 0.25-second chime tones through the front speakers.
The IPC receives the lane departure warning chime request from the GWM over the High Speed Controller Area Network 3 (HS3-CAN).
The GWM receives the land keeping aid warning chime request from the Image Processing Module A (IPM-A) 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.
