Information and Entertainment System - System Operation and Component Description: Chimes
WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
Various vehicle systems send chime requests over the CAN to the IPC. The following are determined as the IPC processes these requests:
- Chime characteristics such as tone, tone length, number of repetitions, and time between tones
- Chime output volume
- Priority of the chime request
- Which speakers (all, front, or rear) will play the specific chime
The IPC sends the processed requests over the CAN to the DSP. The audio DSP module outputs the chime tones to the appropriate audio system speakers as fluctuating AC voltage.
