Function
•
Measures the driving noise level inside the vehicle with a specialized microphone, and the main amplifier
modifies the volume accordingly. Due to this, passengers can enjoy music with constant sufficient volume.
Construction/Operation
•
A microphone is installed on the lower panel.
•
The main amplifier separates the sound inside the vehicle, measured with a microphone, into music and noise,
and compares the noise and music levels at each frequency. Then, volume compensation is performed for
frequency bands where the noise is determined to interfere with the music.

Malfunction detection function
•
The malfunction detection section detects malfunctions occurring in the system.
Memory function
•
The memory function detects a malfunction, changes it to a DTC, and stores it in the memory. The memory can
store a maximum of three DTCs. If another malfunction is detected when three DTCs are already stored, the
memory function clears the oldest DTC and stores the new one.
•
Once a DTC is stored, it can only be cleared by the designated procedure; not by turning the ignition switch to
the LOCK position or disconnecting the negative battery cable. The procedure is mentioned in the Service
Section.
