Parking Aid Chime
WARNING: This page is about a different car, the 2018 Ford EcoSport. 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 FDIM 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.
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.
If not equipped with the base AM/FM audio system and a chime request is received, the IPC sends the IPC chime request message to the ACM or the DSP (Harmon audio system only) to sound the chime through the rear speakers.
