Parking Aid Audible Alert

The speaker increases its warning tone rate as the vehicle gets closer to an obstacle. When an object is detected within 304.8 mm (12 in) of the sensors, the warning tone becomes continuous.

When the PAM  sounds the parking aid tone, it sends an audio volume cutback message to the IPC  which sends a message over the to the ACM  . When the ACM  receives the message, it reduces the speaker output so the parking aid tone can be heard. If the vehicle is equipped with Sony® sound the audio DSP  module reduces the speaker output.
