Parking Aid Chime
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 parking aid system uses a visual display in the FCDIM and a chime to alert the driver objects are close to the vehicle. The parking aid chime sounds a repetitive chime tone that decreases the time off between chime tones as objects get closer to the sensor until a continuous tone is heard through the rear speakers.
The IPC receives the parking aid chime request from the GWM over the HS-CAN3.
The GWM receives the parking aid chime request from the PAM over the HS-CAN1.
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.
